Growing up, I was constantly into sports (Volleyball, basketball, baseball, softball, flag football) and did not think it was necessary to workout. The sports participation would keep me in shape. I was wrong. Unfortunately, it took triple bypass surgery (changing my diet), two hip replacements (walking not running) into my 60s to finally realize working out IS necessary. I was active (treadmill, pingpong, weight machines,Tai Chi and ballroom dancing) until I was 77 years old.
