One of the activities my wife and I used to really enjoy doing together was going to the gym. We had a personal trainer named Eric. Eric was funny, knowledgeable and understood how to maximize the workout for both me and my wife. Having a personal trainer that understood both our individual needs kept us motivated to workout. Eventually we moved and got a gym membership. However, we did not sign up with a personal trainer and the gym experience was no longer that unified activity we enjoyed together like we did when we worked out with Eric.
