If we’re honest, sometimes it would be great to turn off all of our electronic devices, not show up for work, tell our families and friends we don’t want to talk and just take a moment for ourselves. A moment free from distractions, stressors and responsibilities! However in our fast paced digital world seldom do we make time for ourselves or our health.
The heart is the key to life as we know it. If it fails we die. Cardiovascular exercise is a life affirming activity because it is focused on the heart. The idea of cardiovascular training is to stress the heart and cardiovascular system so that we bring oxygen and nutrients to all the tissues of the body and strengthen the heart muscle itself. The process whereby the arteries that transport the oxygenated blood from the heart to the muscles also give us the ability to accomplish the normal activities of daily life.
A cardio training session is characterized by continuous movement over time at a specified rate of speed. Walking for an extended period of time would qualify as a form of cardio exercise. Playing tennis does not qualify as a cardio activity because it does not consist in continuous movement, just as a round of golf doesn’t. Other types of cardio exercise are cycling, swimming laps, hiking, running, cross country skiing and other such activities that require one to work overtime and involve a constant effort to maintain muscular involvement of all the major muscle groups on the body.
1. RESTING HEART RATE: This is measured in the morning before you get out of bed. It is done by placing two fingers on the wrist (radial artery) or neck (carotid artery) for 60 seconds and counting the number of beats. This number can also be found by counting for 15 seconds and multiplying by four. Your resting heart rate is used in calculating training heart rates and will be an indicator of improvement resulting from cardio training. My resting heart rate has been as low as 40 beats per minute (the average is 72 bpm).
2. TARGET HEART RATE: The idea of establishing a target heart rate is to “find your starting place” and determining the intensity during your training session. Each bout of cardio can be anywhere from 20 minutes to an hour or more – depending upon your fitness goals and preparedness. The more conditioned one is, the more “work” one can do in a shorter period of time – burning more calories as a result – and strengthening the heart as well. To determine your target hear rate, take 220 minus your age and that will give you a rough “maximum heart rate”. Multiply that result by 50-85% to establish the range for your heart rate. In my case, I’ll be 70 in August, so:
220 – 70 = 150 (maximum hear rate)
150 x .5 = 75 beats per minute (low end)
150 x .85 = 127 beats per minute (upper limit)
Knowing these two parameters is important – for both success – and safety. The less conditioned you are, the lower the intensity you should start from. The more conditioned you are, the more intensity you can bring to your chosen activity. Intensity is determined during and after the activity by counting the number of beats in a 6 second count and multiplied by ten.
If you have questions do seek the assistance of a fitness professional in guiding you to your own individualized program. Do consult a medical professional before beginning ANY exercise program requiring an understating of your current fitness levels while discovering any personal limitations that may have such as joint issues, heart issues, blood pressure issues, medications and other potential “red flags”.
Being aware of the many benefits of cardio training and reminding yourself about them is crucial to ensuring that you remain committed to your fitness and health goals.
The amount of blood pumped by the heart in one contraction is called stroke volume (SV). Stroke volume improves as a consequence of cardio training resulting in decreased blood sugar levels, improved lipid profile (circulating fat called triglycerides), improved stress responses, a calming of the mind, and increased energy levels to mention just a few. Here’s a more detailed list of the benefits of cardio training:
Improved respiratory function:
Improved heart function:
Increased fitness level:
Improved metabolism:
Increased overall wellness:
The many gifts of cardio training are known but the key to this process is the body’s increased ability to burn calories. Weight management, maintenance – and indeed weight loss – is a known benefit of cardio exercise. If we train our bodies to anticipate a period of heightened calorie burning each day we will establish the greatest result of all: a higher resting metabolic rate that supports all levels of health for us.
These benefits are valid reasons for embracing cardio training on higher and more challenging levels and should motivate you to incorporate some form of this training into your daily life.
I started running to relieve the stress of homesickness during my freshman year at Syracuse University and fortunately for me it developed into a lifestyle that I carried into the next decades of my life. When I think of the years I have been a runner, I am so grateful I found something so healthy for my body, mind, spirit – and heart. I am convinced that running saved my life.
Due to injury to my feet these past few months (inflammation and pain), I reduced the running and started riding a stationary bike to allow my injuries to heal. It took time, but it has worked and I am running pain free now (with the help of new shoes and inserts). I am now incorporating cycling sessions into my training routine to minimize the risk of additional plantar fascia injury. This is what I mean by being flexible and listening to your body.
I love running fast and will for as long as I can. It is the way I love to run as I enter my 70’s. Jogging was never for me so I “play” with each program I do and challenge myself daily to improve – or reach for higher goals. It energizes me – and it will do the same for you as well.

Often called the “silent disease,” osteoporosis is approaching epidemic proportions. Twelve million Americans have osteoporosis, and an estimated 37 million (80% of women) have low bone density, a strong risk factor for the disease. Men and women from all races and backgrounds can develop osteoporosis. Osteoporosis drains bones of mineral content, and although the disease often has no symptoms, it causes more than 1.5 million fractures each year.
So, what causes osteoporosis? The cause can be linked to several things such as age, gender, heredity, nutrition, lack of exercise and menopause. The primary cause of osteoporosis is related to the dramatic decrease of estrogen in post-menopausal women. Estrogen is responsible for inhibiting excessive bone breakdown and balancing the levels of calcium available to the bones. Your bones are living tissue which absorb calcium through the blood and store it in the bones which causes an increase in bone density. When the blood level calcium decreases or is disturbed through lack of estrogen, the result is the loss of bone tissue.
What happens when your bone density decreases? Because the bones are unable to absorb calcium, your bones may become weak and brittle to the point when your bones fracture or crack. Unfortunately, many times osteoporosis is not detected until a fracture has occurred. Fractures usually occur in the wrists, spine or hips. This is because these areas are made up of the most porous and metabolically active bone tissue in the body known as trabecular bone. A fracture means loss of independence and functional capacity, severe pain and even death. Hip fracture complications can be fatal.
To increase bone density, you must exercise your bones which means you must impart mechanical forces to the bones. This is done in one of two ways: gravitational support of the body weight by the skeleton is the natural way and its effectiveness is based on your body weight. People who are overweight actually have denser bones because of the increased amount of body weight their skeleton has to support. This is probably the only advantage to being overweight, however, eventually the decrease in estrogen will cause the bones to break down faster than it can rebuild itself and osteoporosis will occur!
The only other way to impart mechanical forces on the bones and exercise the bones would be through muscular force resulting from the contraction of muscles attached to the skeleton. This type of stress can only occur through resistance training which primarily consists of exercising with resistance machines or doing weight training exercises with free weights. Like muscles, bones respond to this type of stress and become bigger and stronger. In addition, resistance training will increase the blood flow to the bones and results in hormonal changes which enhance bone nutrition and growth.
If you show signs such as stooped posture, fractures, or stress fractures, you should contact your physician for a bone mineral density test. Risk factors that may increase your risk for developing osteoporosis are:
There is no cure for osteoporosis, but exercise and diet are keys to prevention and may even reverse some bone mass loss. Calcium supplements are a good idea, however, osteoporosis may begin as early as your mid-thirties and, therefore, early intervention is a must. Besides sufficient calcium intake, vitamin D plays a major role in calcium absorption. The recommended daily intake for vitamin D is 400 international units (iu). Additionally, supplements have been proven mostly ineffective if not taken in conjunction with an exercise routine. Exercise enhances the bones’ ability to utilize dietary and supplemental calcium, thus the best way to reduce your risk of developing osteoporosis is to start at an early age making sure you take in 800-1,500 milligrams of calcium per day, 400 iu’s of Vitamin D per day and exercise regularly. Additionally, refraining from smoking and excessive alcohol use is vital.

In our youth we all have power – power of thought, anticipation, joy, action, mystery, imagination and so much more. As we get older, we lose our wonder of the power of our own life. This term also refers to our physical power. I know that when I am doing my weight training I am addressing my power and physically: it is made very clear to me while I am bench pressing 250 pounds 20 times.
As we age, it is even more important to exercise consistently and include balance and flexibility challenges into our exercise routines more frequently. Various forms of exercise are vital to the body’s ability to function efficiently and repair itself. The benefits of consistent exercise to one’s health are almost countless.
In 2016, there are expected to be 246,660 new cases of invasive breast cancer and 61,000 new cases of ductal breast carcinoma in situ (DCIS). More than 2.8 million individuals have survived breast cancer. Breast Cancer is the most common cancer in women other than skin cancer.
Aquatic rehabilitation consists of planned, progressive physical exercises to reduce the chance of further injury, enhance function, and optimize overall fitness and health. Commonly seen diagnoses include musculoskeletal injuries to include simple to complex fractures, spinal cord injuries, and amputations.
Too many athletes spend too much time complaining about their bodies: I feel too fat. I’m too thin. I want a six-pack ab. I hate my spare tire.
I have been a personal trainer and strength and conditioning specialist for 24 years, but first and foremost, I am a parent to a high school and collegiate athlete. My son and daughter have been playing basketball since they were very young and have endured a multitude of overuse injuries (because who listens to their mom right?).
