As I was approaching my 60th birthday (next year), I realized I only had about ten years until I reach middle age. I decided I wanted to get in shape for this milestone, so I joined X-Team. I had been walking my dog a couple of miles in the park every day, so I thought this would an easy transition. Not so. At my first workout, I couldn't do but a few pushups and sit-ups, and had to take quite a few breathers during the running, jumping jacks, and other exercises.
