Our heart is at work literally 24/7 for us and without it doing this constant job for us, well, we know the consequences. An irregular heartbeat (arrhythmia) can pose complications that increase the risk of having a stroke or even heart failure. It can be frightening for someone and can also impact their daily living.
Weight management is a, if not the, Holy Grail of lifestyle change for many, especially for women. Not that men don’t seem as concerned about their weight; it’s just that many men don’t see themselves as overweight when they look in the mirror – they see the same kid who played ball in high school.
Normally, I do not like to focus on weight loss. In taking a health professional’s perspective on weight, it’s just a number…until it’s not.
That is, focusing on weight is an excess we in the West – the wealthy, industrialized, relatively-safe from famine and disaster societies – tend to overindulge ourselves with. But, for those same reasons, we also are prone to illnesses and diseases that correlate with our lack of food scarcity. Thus, watching one’s weight is synonymous with watching one’s health unless one goes to extremes such as with eating disorders/disordered eating.
With this in mind, the advent and profusion of interest and usage of anti-obesity medications (AOMs) such as Wegovy, Ozempic, etc. are worth addressing.
As this blog post from the American College of Sports Medicine by Renee Rogers, Ph.D. FACSM (Dec. 18, 2023) discusses, the health and fitness professional (HFP) might feel threatened by a flurry of OAMs that might detract from his/her potential market. People who are trying or need to lose weight can now do so without having to engage the services of the HFP. In her essay, she notes that OAMs do work very well but that permanent weight loss and subsequent health and functionality still depend on maintaining a fit and strong body.
Also, now that we have meds that prove, essentially, that weight loss is not simply a function of willpower – that, because they work by effecting hormone changes that signal the brain and the GI system that they are not hungry, overeating is not necessary (excuse the simplification), people can now attend to engaging in healthful exercise and activity for other purposes: health (obviously), fitness, energy, fun, etc.
Finally, allow me to introduce Sheila Olsen, a freelance author on topics pertinent to health, fitness, and diet. Below is her excellent and well-researched review of weight loss for women. Thank you, Sheila, for reaching out to me and offering to contribute to the STEPS Fitness blog:
Being healthy and at a healthy weight is important for everyone, but women have different health concerns than men and often lose weight differently.
The Differences
The biggest reason why men and women lose weight differently is hormones. For women, hormonal changes due to menstruation, pregnancy, and menopause can cause them to gain or lose weight. In addition, the hormones that control a woman’s appetite and metabolism are different from those that control a man’s. This means that women often have a harder time losing weight than men.
Another reason why women and men lose weight differently is that they tend to eat differently. Men are more likely to eat high-calorie foods and snacks, while women are more likely to snack on healthier foods like fruits and vegetables. This difference in diet can also lead to different rates of weight loss.
Though there are many reasons why women and men lose weight differently, the most important thing is that both sexes should focus on eating healthy foods and exercising regularly. By doing this, nearly everyone can achieve their goals for healthy weight loss, or at least healthy living.
Personal Training
Personal training services are specifically designed to support women on their weight loss journey, offering tailored fitness programs that cater to individual goals and needs. With a focus on sustainable and healthy weight loss, these services include one-on-one coaching, nutritional guidance, and customized workout plans that are both effective and enjoyable. The experienced trainers at Steps Fitness understand the unique challenges women face in losing weight and are committed to providing the motivation, support, and expertise needed to achieve lasting results.
Working Out at the Gym
Another great strategy for losing weight is to join a gym. Gyms offer a wide variety of machines and classes that can help you lose weight and get in shape. When working out at the gym, include cardio exercises such as running or elliptical training. Strength training is also crucial because it will help you build muscle mass, allowing you to burn off calories throughout the day.
Eating Mindfully
To lose weight, you must be mindful of the foods you eat. This means choosing healthy foods that are low in calories and fat. Diets high in processed foods and sugar can lead to weight gain, so it’s important to avoid these types of foods when trying to lose weight. Instead, focus on eating fresh fruits and vegetables, lean proteins, and whole grains. Additionally, be sure to drink plenty of water as this will help you stay hydrated and full throughout the day.
Consuming Caffeine
Caffeine is often highlighted for its potential effects on weight loss, especially among women, due to its ability to increase metabolism and enhance fat burning in the short term. Moderation is key, as excessive caffeine consumption can lead to unwanted side effects, so understanding and managing intake is crucial for leveraging caffeine’s benefits for weight loss effectively. For women considering caffeine as a part of their weight loss strategy, it’s important to be aware of the caffeine content in their favorite beverages. Online resources can be incredibly helpful for this, offering detailed information on the caffeine levels in various drinks, from coffee and tea to energy drinks and sodas. By consulting these resources, women can make informed decisions about their caffeine intake, ensuring it aligns with their health goals and dietary needs.
Staying Hydrated
As mentioned above, staying hydrated is key to losing weight. Drinking plenty of water throughout the day will help you feel full and satisfied so that you’re less likely to snack on unhealthy foods. In addition to water, green tea is an excellent beverage for weight loss as it contains antioxidants that can boost your metabolism. Aim to drink eight glasses of water or green tea per day.
Choosing the Right Health Insurance
Health insurance is an important factor to consider when it comes to trying to lose weight. Choosing the right health insurance plan can help you by providing meaningful support and resources that can make a huge difference in achieving your weight loss goals. Insurance plans can provide access to effective nutrition counseling and consultations. If you’re currently self-employed and not covered, you still have options. You can explore health insurance plans through the Freelancers Union or Affordable Care Act, or you can join your spouse’s plan.
Establishing SMART Goals
It can be helpful to establish SMART goals for your weight loss journey. SMART stands for Specific, Measurable, Achievable, Relevant, and Time-based goals. These goals should be realistic and attainable so that you don’t get discouraged along the way.
For example, a SMART goal might be “to lose 10 pounds in three months by eating mindfully and exercising three times per week.” This goal is specific (lose 10 pounds), measurable (three times per week), achievable (exercising three times per week), relevant (lose 10 pounds in three months), and time-based (in three months).
Managing Stress
One common health concern for women is managing stress. Stress can have many negative effects on your health including causing weight gain. When trying to lose weight, it’s crucial to find ways to manage your stress. Getting regular exercise, practicing meditation or deep breathing, journaling, spending time outside, and spending time with friends or family can all help.
How Surgery Can Help
Weight loss surgery, such as gastric bypass or sleeve gastrectomy, can be a beneficial option for individuals struggling with severe obesity and related health issues. These surgeries can lead to significant and sustained weight loss, helping to reduce the risk of obesity-related conditions like diabetes, hypertension, and heart disease. Furthermore, they often lead to improved overall quality of life and increased mobility for those who have struggled with obesity for an extended period, making them a valuable tool in managing long-term health.
Whether you’re working with a personal trainer, walking more often, or finding a better health insurance plan, these tips can help women lose weight in a healthy way. Remember, every woman’s body is different, so what works for one person might not work for another. The most important thing is to find what helps you and stick with it. With consistency and perseverance, you can reach your goal weight and stay healthy!

Dr. Irv Rubenstein graduated Vanderbilt-Peabody in 1988 with a PhD in exercise science, having already co-founded STEPS Fitness, Inc. two years earlier — Tennessee’s first personal fitness training center. One of his goals was to foster the evolution of the then-fledgling field of personal training into a viable and mature profession, and has done so over the past 3 decades, teaching trainers across through country. As a writer and speaker, Dr. Irv has earned a national reputation as one who can answer the hard questions about exercise and fitness – not just the “how” but the “why”.
Musculoskeletal issues have become the number one reason for physician visits.(1) Doctors are starting to agree that many surgeries may have been unnecessary.(2) The opioid crisis is a symptom of a larger societal issue to be sure, but it appears that too many people are turning to pain medications to manage their various aches and pains. Certainly pain medication and surgery can help many diseases and symptoms. However, they can also have long-term detrimental effects on human health. Can supervised exercise contribute to helping the problems of too many surgeries and too many pain medications being prescribed?
The modern research on this subject continues to support the notion that properly dosed and executed exercise can have a long-term positive impact on pain and possibly reduce the need for surgery. Who in the health and wellness community conducts supervised exercise? The Personal Fitness Trainer and Exercise Professional.
Personal Trainers are sought out to create fun and challenging workouts, help people lose weight, or help athletes perform better for their sport. We feel that although important, this puts exercise professionals like personal trainers in too narrow of a box.
Can a Personal Trainer be more?
Can an Exercise Professional transcend these service niches and be considered part of one’s healthcare team?
We not only believe so, we think that we must.
Exercise has more power than we, and the exercise consumer, give it credit for. Exercise can stimulate powerful natural medicine to help individuals overcome chronic pain and possibly even avoid surgery.
Our goal is to trumpet this message to exercise professionals and consumers alike and work to support the development of the exercise professional to meet this demand. Our plan is to be one of the pioneers that move exercise to the forefront of healthcare as a powerful, and often overlooked, process to be integrated proactively within a healthcare team for supporting individual health where pain persists and surgery is being considered. Will you join us?

Pain is a very personal and subjective experience. Modern pain science no longer views pain as a sensation; rather, pain is viewed as an experience that results from an amalgamation of inputs that are physical, psychological, emotional and social. These inputs must be viewed interdependently, because they all directly affect one another and the overall pain experience.
Researchers and clinicians have structured the bio-psycho-social (BPS) model of modern pain to better understand and treat chronic pain.
“Bio” represents biology, biomedical and/or biomechanical. This is the historical way chronic pain was treated—seeking disease, dysfunction or damage and then designing interventions that would address it.
“Pyscho” represents the current psychological characteristics of the chronic pain sufferer. This could include the individual’s beliefs about his or her situation, historical references related to past pain experiences, anxiety, depression and expectations about the future. Many of the psychological elements are influenced by family members and/or perceived experts or authorities (e.g., doctors, nurses, physical therapists and personal trainers).
“Social” represents the social implications of the pain experience. Social stressors relate to doubts that those around us don’t believe our pain is real and whether there is a social support structure in place. Additional stressors may be related to missing important social events, traveling or the inability to maintain employment or familial responsibilities.
The International Association for the Study of Pain defines pain “as an unpleasant and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.” The word “potential” is significant in this definition because it describes pain even in the absence of tissue damage.
In a 2018 paper, the Centers for Disease Control and Prevention (CDC) noted that 50 million Americans suffer from chronic pain and 20 million suffer from high-impact chronic pain. High-impact chronic pain is chronic pain that “frequently limits life or work activities,” according to the report.
As a health and exercise professional, the likelihood of working with clients who have chronic and/or recurrent pain is high. These are clients who have been cleared for exercise by their physicians and who have either completed or are currently involved with treatment by a licensed medical provider such as a physical therapist or chiropractor. Understanding evidence-based strategies for exercise and maintaining professional scope of practice provide an important service to this population. Exercise programming to reduce mechanical stress and improve movement confidence and function are well within our professional role. But at no time should a health and exercise professional attempt to treat or diagnose any condition or provide medical advice.
The growing body of evidence around pain is reshaping treatment approaches by medical professionals. As a health and exercise professional who will very likely work with clients experiencing chronic pain, understanding the bio-psycho-social paradigm and what it means in reference to program design, communication and expectations are paramount.
One of the most effective strategies for introducing physical activity to clients with chronic pain is to establish rapport, which in turn, may help relieve anxiety and fear and set expectations. Here are three strategies to get you started:
Pain is a complex issue and it is neither helpful nor accurate to approach client communication and programming from an outdated paradigm. The current bio-psycho-social model contains elements of biology, psychology and sociology, of which all must be taken into account for lasting, pain-free movement.

More people are starting to question the accuracy of the BMI (body mass index) measurement. Essentially, this is a measure of your weight to height ratio. Maybe this formula is outdated going back to Lambert Adolphe Jacques Quetelet’s 1832 development (your weight in kilograms divided by your height in meters squared). Popularity didn’t strike until the 20th century when insurance was being evaluated for risk potential and among specific populations.
There are more health claims made about vitamin D than perhaps any other vitamin. Media stories touting vitamin D for this ill or that are common, particularly in the age of COVID-19. We’re also frequently told Americans don’t get enough vitamin D, with surveys showing as many of 40% of individuals have below optimal amounts in the blood. So how do we get vitamin D and what claims are true and backed by research? Let’s take a closer look at vitamin D to flesh out what we know for sure and where more research is needed.
Molecularly, vitamin D is a group of fat-soluble compounds with a four ringed cholesterol backbone. What’s most important to know is that it comes in two forms — as vitamin D2 in food and as vitamin D3 in our skin.
Vitamin D3
Our skin is our primary source of vitamin D, but it begins there as an unorganized and inactive form, requiring UV exposure to convert to usable vitamin D3. Conversion via UV light is exceedingly efficient, and it’s estimated brief exposure of the arms and face is equivalent to ingesting 200 international units day. Conversion varies however with skin type (darker skin converts more), latitude, season and time of day. Infants, disabled persons and older adults often have inadequate sun exposure as well, and the skin of those older than 70 also does not convert vitamin D as effectively. Interestingly, vitamin D also requires temperature to be activated, so you may not get as much of a benefit from sunlight in the winter months as you might expect.
Vitamin D2
Because it is fat-soluble, dietary vitamin D2 is best absorbed with fat in the diet and fish is a common source. Uptake can be negatively impacted by disorders associated with fat malabsorption such as celiac disease, Crohn’s disease, pancreatic insufficiency, cystic fibrosis, short gut syndrome and cholestatic liver disease.
Once activated and in the bloodstream — either by UV exposure or absorption through the diet — the liver converts vitamin D to 25-hydroxyvitamin D (25[OH]D), and then the kidneys further convert it to 1,25 hydroxyvitamin D, the most active form of vitamin D in the body. For this reason, kidney and/or liver problems can also negatively impact vitamin D levels.
Interestingly, all cells in our bodies have receptors for vitamin D, and this has in part fueled the varying claims as to how it might impact health. What we know for certain is that it helps with calcium absorption in the gut, regulating calcium levels via the kidneys, and regulating parathyroid hormone. Vitamin D’s role in calcium regulation and absorption means it has a direct impact on healthy bone growth and turnover. For this reason, you often see it in calcium supplements.
Research has also shown a clear correlation between Vitamin D and muscle health, including research showing improved lower body strength. Some research has also shown vitamin D can help prevent falls in the elderly.

Determined, consistent and tenacious are just a few words I like to use to describe my Parkinson’s Disease “fighters”. I call them “fighters” because instead of lying down and giving up, they have chosen to take charge of their future. They commit to FIGHT BACK against Parkinson’s Disease, and that is a “fight” I want to join!
It is critical that you observe how the “fighter” moves, processes information and responds to challenges. We utilize that information and create fitness programs to address the motor symptoms those living with Parkinson’s Disease (PD) struggle with each and every day.
And the best place to start is with “Foundational Movements” that will broaden a fighter’s Activities of Daily Living (ADL). People living with PD require a unique fitness program to address the impact that PD has on their ADLs.
Squats
Lunges
Hinge
Push
Pull
Carry
Rotation
I encourage Fitness Professionals to start with the most basic form of each Foundational Movement before progressing to a more challenging version. Neurologically, progressive and regressive movements make an impact on people living with PD. I have learned that repetition and exercise phases are a necessary part of any fitness program, similar to the human development process.
Consider how humans learn how to move from birth to 3 years of age. First, we learn a skill such as rolling over and we repeat it until we succeed. Then, we move on to unsupported sitting, followed by crawling until one day we are up and running!
And just in case you are wondering, the best place to start with foundational movements is in the warm-up. The repetition of the drills enables the fighters to improve their form, prepare for the work phase and create new neural patterns that will improve their functionality.
Let’s briefly discuss the movement patterns and how each movement can improve ADLs.
This movement pattern is used daily and assists in maintaining the ability to use synergistic muscular tension, stability and mobility through the torso, hips, knees and ankles. However, every fighter is different which means they will need to start at different levels.
| EXERCISE | ADL |
| Seated knee extension | Toileting |
| Wall Squat | Showering |
| Squat | Dressing |
| Squat/stand and lift heels | Cleaning |
| Squat-jump | Care-giving |
Falling or the fear of falling is a significant issue for people living with Parkinson’s Disease. The ability to stand on one leg, shift weight back and forth, maintain an asymmetrical split stance, bend down or get up off the floor is crucial for fall prevention. Lunging, in its various stages, provides Fitness Professionals a way to identify weak links.
NOTE: Some overlap will occur with the lunge and hinge movement.
| EXERCISE | ADL |
| Tap one foot behind | Vacuuming |
| Reverse Lunge | Stepping in/out of shower |
| Step one foot forward | Tying shoelaces |
| Forward lunge | Walking up/down stairs |
We ALL need to strengthen our posterior chain but it seems to be the one area many Fitness Professionals shy away from including in their program. When you consider how many times a day someone bends over, they must have the strength and basic knowledge of how to hinge so they don’t fall or hurt themselves.
This is even more important for people living with Parkinson’s Disease. If they fall, it could take months for them to recover and by that time, the disease has progressed. Make it a goal to include a hinge movement in every routine.
| EXERCISE | ADL |
| Basic Deadlift with arms crossed | Getting in/out of car |
| Supported Deadlift with one foot behind | Toileting/Showering |
| Traditional Deadlift with weights | Dressing |
| Single Leg Deadlift
Cross-over Deadlift | House and Pet Management |
The push-up is one the most popular exercises of all time! Mastering the “push” is a different challenge. The “push” (not always push-ups) requires core stability, upper back and shoulder strength. Once mastered, people living with PD will notice an increase in power and strength.
Word of caution: Parkinson’s Disease typically affects a person’s posture. Please remember that anything overhead will alter the center of gravity which means some fighters need to perform a “push” exercise that keeps the arms closer to the body.
| EXERCISE | ADL |
| Wall Push-up | Rising from the floor |
| Push-up on Smith Machine Bar | House cleaning |
| Push-up on knees | Showering |
| Push-up on hands/toes | Pushing large door open |
With so many postural issues due to weak muscles, developing a stronger “pull” will help people living with PD strengthen their back muscles which will decrease falls, improve posture and relieve back pain.
| EXERCISE | ADL |
| Shoulder retraction only | Opening refrigerator |
| Shoulder retraction and hold | Vacuuming/sweeping |
| “Row” arms (no weights) | Showering |
| “Row” with tubes | Pulling up pants |
| “Row” with one arm | Picking a child or pet up |
People living with PD want the ability to carry a grocery bag, walk and pull out keys all at the same time. But if they do not know how to use their body correctly, multitasking can be scary. Carry exercises focus on leverage and load. The good thing is we can always make adjustments depending on other variables. For example, bad shoulders mitigate against the overhead version of the carry while weak hands prevent one from carrying heavy loads. Carry exercises don’t necessarily help prevent falling other than the benefits they provide by strengthening the core. However, Fitness Professionals need to remember that carry exercises will serve your fighters in the early pre-kyphosis stage as a posture exercise. Carry exercises also provide a challenging asymmetrical exercise if performed unilaterally.
TIP: The carry movement is a great way to challenge the core without doing crunches!
However, before beginning a gait/carry movement with your fighters, make sure they have been thoroughly assessed.
| EXERCISE | ADL |
| Walking | Carrying groceries |
| Bird dog walk | Carrying laundry basket |
| Farmer’s walk with two weights | Child care |
| Farmer’s walk with one weight | Pet Care |
| Farmer’s walk with one weight overhead | House Management |
The core maintains the stability and strength of the torso and acts as a conduit for energy. The movement patterns listed above encourage core strength which means rotational exercises are not so much a movement pattern as a powerful supplement to the above foundational movements.
Rotational exercises for people living with PD help improve gait and posture, reduce falls, improve coordination and mobility, increase overall strength and, most importantly, enable them to independently perform ADLs.
Rotation Reminders for Fitness Professionals:
Caution! Be sure to include the hips and the lower portion of the spine when rotating.
| EXERCISE | ADL |
| Isometric tube hold | Enter/exit tub or shower |
| Isometric tube hold and step laterally | Enter/exit vehicle |
| Circles with tube | Emptying dishwasher |
| Circles with tube/squat | Laundry related activities |
| Torso rotation with tube | All ADL categories |
In closing, when Fitness Professionals learn the art of organizing movement patterns and creating a program that uses these foundational movements, their fighters living with Parkinson’s Disease experience physical gains such as standing without support, joint mobility, active core stabilization, integrated joint action, cognitive improvement and most importantly the ability to handle a challenging moment with confidence.
Having acquired these foundational skills with the help of you, their Fitness Professional, build trust and credibility for supporting a fighter’s long-term commitment to HOPE. As noted at the beginning of this article, our fighters are determined, consistent and tenacious. They have chosen to take charge of their future and FIGHT BACK against Parkinson’s Disease — a “fight” I hope you, as a Fitness Professional, join!

GLP-1’s are proving themselves as medical phenoms. They have been in existence for many years in the treatment of diabetes. They have demonstrated themselves as capable of reducing cardiac events, lowering blood pressure, cholesterol, heart failure symptoms, and even strokes. They have shown themselves effective in reducing the kidney problems that diabetes can cause in the long run. And there’s even proof that they might be useful for treating childhood obesity. Ultimately, they may prove valuable for medical conditions we haven’t yet explored. In light of the budding awareness of the strong correlations between our obesogenic diets that are high in fats, sugars, and calories and a variety of diseases ranging from some cancers to musculoskeletal ones, GLP-1’s may be the super-duper drugs that have exploded the weight loss market.
However, if weight loss is a goal and semaglutides and other similar hormone-affecting drugs is your method then, young or old, male or female, preserving muscle mass is critical. As a female, especially, whether pre- or post-menopausal, preserving muscle mass is even more critical as rapid and large amounts of weight loss includes bone density loss, too. Muscle mass training enhances bone mass accrual IF…, and this is a big IF, the weights you lift are heavy enough to be deemed ‘intense’.
The American College of Sports Medicine recommends that, for health, people should do some kind of RT should be done at least twice a week but could be done 3 or more if the program allows for sufficient recovery between sessions. A 2/wk program should consist of at least one exercise for each body part – legs, core, upper body/arms; ideally, you do 2-3 exercises per body part but they do not have to be the same exact exercises. For example, a heel raise gets the calf muscle, a squat and lunge also get the calf muscle, but they also get the upper leg and core.
If you choose to do 3 sessions/wk, be sure to space them out with at least 36-48 hours between sessions. For a more athletic program, it’s not unusual to do 4 or more sessions/wk but intelligent design must be applied to avoid overuse and overtraining, and injury.
What Constitutes a Viable Resistance Training Program
In the realm of RT, there are many models to consider, each with 4 variables: frequency, intensity, duration, and exercise type. Frequency we’ve already addressed. Duration is a function of how long you want to spend doing the exercises; some quick and dirty routines can last as short as 15 minutes or you can drag it out to an hour or more. But intensity and type are where special attention should be made when the training is being done to minimize loss of muscle and bone.
When discussing intensity, we’re talking about a percentage of your maximal ability. Most of us will never test our max so let’s use a common way of determining intensity: to volitional fatigue. That means that when you feel you can no longer do any more repetitions with good form and no compensations, you have reached volitional fatigue. It is very subjective and varies according to how you are feeling at the moment, including stressors outside the gym. Recognizing that many people with overweight and obesity have not been in the gym in a while or are not comfortable going to a gym, it may take a few sessions with modest weights to figure out what it really feels like to be fatigued at the end of a set of an exercise.
There’s no hard and fast rule but, if bone loss is one of your issues, either due to age, menstrual status, sedentary lifestyle, or poor diet, it is recommended that you try to fatigue in 10-12 repetitions; that corresponds to a heavy enough weight to provide a good stimulus for bone to accrue. With the understanding that most people who do not have RT experience won’t feel comfortable trying to achieve that kind of load/intensity, especially if they’d had any injuries or are prone to some, such as to the rotator cuffs in older adults, the process of ramping up to weights that can mitigate bone loss should be long, slow, and properly designed to reduce risks. See your local trainer….or call us at STEPS.
Exercise type, however, is where the message of RT in combination with drug-enhanced weight loss is most critical. While many people aspire to 6-pack abs (abdominals), that is an unreasonable goal, especially for those who have carried excess fat around their midsections or those who are older. Having a strong core – those muscles from the mid-thigh to the mid-thorax, front, sides, and back – is valuable but not essential for the average person. Having a functional core, on the other hand, is. A functional core is one where all the muscles know how to work together and have sufficient endurance and strength to allow you to perform activities of daily living, work, and recreation.
Exercise Selections and Options
Allow me to provide some specific exercise types that will strengthen muscles and bones that we all need in order to accomplish what a rapid weight loss system detracts from, especially for post-menopausal women.
Bone loss from the hips/upper femur, which contributes to falls and fractures in older people, can be countered with such exercises as a leg press machine, weighted squats, lunges, and step-ups.
Bone loss in the lumbar spine can be slowed with such exercises as weighted squats, lunges, step ups as well as deadlifts, bird dogs, and stability ball bridges or hip lifts. You can make the latter more demanding to achieve volitional fatigue by adding small arm and leg movements during the birddog and doing bridges with one leg rather than both.
Bone loss of the upper spine, which affects posture, especially potential dowagers humps in older adults – which is exacerbated in our texting and computer-based lifestyles –
Finally, wrist bones, which tend not to get much training beyond middle school for most females once PE coaches don’t make you do push-ups, are prone to breaking when falling. They are often the first markers of middle age women’s bone loss at the early stage of osteopenia should they experience a broken wrist from a fall. In fact, though, push-ups or some version of a chest press or bench press are some of the exercises that load the wrist and could help build bone IF loaded sufficiently. However, since the rotator cuff deteriorates with age, and is susceptible to injury from doing those very exercises that could help the wrist bones, it’s wise to train them with caution and avoid the volitional fatigue in 10-12 rep prescription. But it’s also wise to train the cuff muscles to minimize the risk of injury from any kind of RT even if you’re not intending to do these bone-enhancing exercises.
Note that each exercise for each segment of the body is done in a weight-bearing posture, even the chest/bench press. Even something as mundane as a plank in a push-up position constitutes a weight-bearing load capable of producing osteogenic forces that may build wrist bones’ strength.
While it is necessary to proceed with caution as you pursue a bone- and muscle-preserving workout regimen, to pre-condition the core and the rotator cuff muscles to avert injuries that might result from a RT program, within 4-6 weeks one will start to experience muscle mass changes. It could easily take a year or more to note any bone-building changes; first by some imaging technique or by falling and not breaking something, which we would recommend against trying. Ultimately, though, the effort to enhance lean tissue – bone and muscle – facilitates weight loss, fat loss, and quality of life. And, with the health upsides of GLP-1 meds, there’s a good chance that RT will even extend the health-years of your life.
Which is the main reason we all should be doing some RT in our lives.

Dr. Irv Rubenstein graduated Vanderbilt-Peabody in 1988 with a PhD in exercise science, having already co-founded STEPS Fitness, Inc. two years earlier — Tennessee’s first personal fitness training center. One of his goals was to foster the evolution of the then-fledgling field of personal training into a viable and mature profession, and has done so over the past 3 decades, teaching trainers across through country. As a writer and speaker, Dr. Irv has earned a national reputation as one who can answer the hard questions about exercise and fitness – not just the “how” but the “why”.
Super-duper weight loss drugs (originally they were designed to help those with Type 2 diabetes, or T2D) like Ozempic, Wegovy, Mounjaro, et al. have swamped the marketplace because of their unique pharmacologic actions compared to their predecessors. Earlier weight loss drugs and over-the-counter concoctions (like coffee and other caffeine-derivatives, as well as smoking cigarettes, for example) simply sped up metabolism and boost energy. These, then, provided (ab-)users an artificial mechanism by which to burn calories and even avoid consuming calories since energy levels didn’t require them.
What makes these modern drugs so unique is their effects on hunger and appetite hormones. Essentially, they alter or disrupt hormone signaling that tell the gut to stop demanding food and/or the brain to feel satisfied with the food you’ve consumed, presumably before you overeat. That is, those appetite and hunger messages lead people to eat less without – we hope – causing permanent and as-yet-unknown effects on the endocrine system as a whole.
Caveat: while some of these drugs have a relatively long history due to their use in managing diabetes, 5-10 years on the market may not be sufficient to declare with absolute certainty that long-term impacts are not going to crop up.
The past couple of decades have given scientists and pharmaceutical companies greater understanding about the gut-brain connection. Hormones, which are signaling proteins that course throughout the body, often have multiple outlets and receptors that allow one metabolic process to influence or be influenced by another part of the body. One of the most common hormones that most of us have some awareness and understanding of is insulin.
Pumped out by the pancreas, insulin helps manage blood sugar, an essential substrate that feeds all of our organs, especially the brain. The digestive process breaks down carbohydrates into sugars that the blood stream then carries to organs for energy. Ever feel groggy or slower between meals? Well, that’s your brain saying ‘feed me…ideally, with sugars, or carbs’. Ever feel like your energy is waning on a long bike ride or hike? That’s your muscles demanding calories, especially sugar-based calories. The insulin signals drive both the sugar calories from those foods to their respective locales and even help pull stored glucose (a form of sugar) from glycogen stores (sugar formulations the body keeps around in case they’re needed like the liver) between feedings. When insulin is in short supply (as in Type 1 diabetes), sugar can’t enter cells.
However, without receptors on the surface and within the cells to allow insulin to do its job, it is neutered. These dysfunctional receptors are part of the process that leads to T2D: when insulin is unable to unlock the cells that have disabled receptors, the brain, heart, and other organs including muscles are deprived of energy.
A few digestive and appetite hormones have similar roles. Leptin, ghrelin, PYY, and the big kid on the block, glucagon-like peptide 1 (GLP-1) transmit signals of fullness, satiety, and hunger to and from the gut and brain. Without operative receptors, however, some of these signals get disrupted. Obesity itself, regardless of original causality, be it genetics, diet, or lifestyle, is one of those disruptors. With obesity, some of these hormones fail to signal when you are sated or over-signal that you continue to be hungry. GLP-1 works by messaging the digestive system that you are sated. Therefore, for those who cannot get that feeling, GLP-1 receptor agonists – these super-duper drugs – help reduce food intake by reducing appetite…and increasing weight loss.
One of the oldest drugs which originally came from willow tree bark is aspirin. Well-known and long used to reduce fevers, manage headaches, and more recently thin blood for those folks at risk for potentially-fatal blood clots such as after lower-extremity surgery or certain cardiac conditions, can also lead to excessive bleeding in the event a closed-head injury or gastric ulcers due to its effect on the stomach lining.
Semaglutide and liraglutide, two of the main GLP-1 drugs out there, have been found to reduce food obsessions leading to calorie restriction but, oddly, have been correlated with reducing other addictive obsessions from gambling to sex to alcohol and other drugs. (1) Interestingly, in combination with bimagrumab, semaglutides “led to superior fat mass loss while simultaneously preserving lean mass despite reduced food intake”. (2)
However, a disconcerting unintended consequence of these weight loss meds is that “the potential health benefits of diet-induced weight loss are thought to be compromised by the weight-loss-associated loss of lean body mass, which could increase the risk of sarcopenia (low muscle mass and impaired muscle function)”. (3) Any time you diet, some of the weight you lose, after initial water weight, is lean tissue – muscle mass and, if rapid and extensive weight is lost, bone mass. A meta-analysis of 18 well-controlled studies that included over 1300 subjects confirmed that these kinds of drugs, which were originally designed to help those with T2D, contribute to loss of muscle mass; metformin, another T2D drug, on the other hand, does not. (4)
Some studies show that, “compared with persons with normal weight”, those with obesity have substantial muscle mass to support and transport their bodies, but poor muscle quality, that is more fatty infiltration generally from lack of a training stimuli. Somehow, though, the “diet-induced weight loss” reduction of muscle mass happens “without adversely affecting muscle strength”. This maintenance of muscle mass that accompanies weight loss improves overall physical function, likely due to the loss of fat mass which otherwise is a drag on performance. While it is recommended, and is very vogue, to encourage a high protein intake – of 1.2 – 2.0 grams/kg of body weight vs the RDA recommendation of 0.8 g/kg – to preserve lean body and muscle mass during weight loss, apparently this does not improve muscle strength; and it could have “adverse effects on metabolic function” if kidney problems are an issue or become one.
Finally, while both endurance exercise, if performed at pretty high intensities such as stair climbing or cycling with high resistances, and resistance training (RT) at moderate to heavy loads “help preserve” lean tissue during a weight loss regimen, only intensive and consistent RT improves muscle strength. This is why researchers are so heavily promoting RT as a way to prevent the inevitable loss of muscle and to restore the low-quality muscle that people with obesity have to a more functional variety. (3)
The mechanisms for these drugs’ effects on lean tissue are under investigation. One group of researchers has determined that the combination of these drugs actually protects against muscle atrophy. The biochemistry is irrelevant here. What might be more relevant is the customary fact that rarely are these drugs prescribed together. So, while they might prevent this adverse effect, it will require more study before they are co-prescribed. (5) There is evidence that shows that oral semaglutide, when prescribed for T2D patients, does help with weight loss and, even alone, does not lead to substantial loss of muscle mass. (6)
As we discussed above, any significant amount of weight loss is accompanied by muscle and even bone loss, especially if done quickly over a short period of time. This could be diet-related, disease- or medical treatment-related (think: during chemo or radiation for cancer), or even, shockingly, exercise-related. Yes, if someone engages in intensive and long-duration cardio training such as running or biking, and weight loss occurs, so, too, does muscle loss. (Real News, Nov 2024)
Why? It’s pretty simple: unless sufficient calories are consumed to compensate for the excess energy output, the body becomes very efficient by discarding muscles that are not used in the training (REAL News – Dec. 2024) or simply allowing unused muscle fibers, like the bigger, stronger, more powerful fast-twitch fibers, to atrophy since neural stimulation is withheld. Even young athletes on a hypo-caloric diet designed for weight loss lose muscle mass unless they’re on a significantly-elevated protein intake diet. (7) Sadly, too, weight loss of 5% or more is accompanied by bone density loss! (REAL News – December 2018)
With studies showing that GLP-1’s can lead to 15 – 24% weight loss, they can be accompanied by 10%, or ~6 kg, of muscle mass loss. (8) Sergeant et al (2019) found in over half of the studies included in their meta-analysis of the same year, the proportion of muscle loss was somewhere between 20% and an astounding 50% of the total weight lost! (9) A more recent study by Bikou et al. confirmed that, while extremely effective for fat loss, these meds can cause up to 40% of the weight lost being lean mass. (10)
All of these researchers concluded that, with intensive RT, not only can patients reduce the muscle loss, they can maintain muscle mass to reduce weight re-gain should they stop taking the medications.
Takahashi et al (11) demonstrated that vitamin D supplementation, and possibly vitamin B12, but not vitamins A, B6, C, and E, might correlate with with the loss of lean tissue in older adults with T2D. Thus, in addition to a vigorous RT program, getting in extra D could reduce the atrophy that accompanies weight loss.
Nunn et al., in a study of diet-induced mouse obesity, found that blocking a particular muscle cell receptor that is known to interfere with muscle growth – ActRII – while being treated with a semaglutide medication preserves muscle mass. It actually induced an almost 10% increase in lean mass!However, this is what you might call a proof of concept study and has not yet been approved for humans taking a GLP-1 drug. (12)
Some studies have found that muscle mass loss does not deteriorate as much in patients with T2D as one might expect. (6) The Japanese subjects experienced substantial health benefits over the 24 months they used a combination of liraglutide and semaglutide, affirming Klausen et al.’s (1) finding. Too, Gurjar et al. found that “drug repositioning” with liraglutide might be the answer to weight-loss-induced muscle loss, at least in mice. (13)
There is a new kid on the block in Phase 3 studies – a combination drug of Amylin + two GLP-1 drugs – semaglutide and cagrilintide – that offers comparable weight loss while helping to “preserve the reduction in energy expenditure” which could help maintain weight loss in the long run. (14) This could be the game-changer what with all these super-duper drugs that are helping people lose weight, especially for those who are older, more likely to have blood sugar control issues such as T2D, and may already have suffered age-related sarcopenia. However, for all patients who are taking these GLP-1’s, the basic prescription still holds, whether or not it totally reverses years of sedentary living or age-related muscle loss, and that’s RT using loads greater than body weight.
