I believe the key to exercise is exercising reasonably, in moderation.
Antioxidants may be helpful for free radicals caused by exercise.
I cringe when I hear of exercise instructors (aerobics, jazzercise, others) teaching 15- 20 intensive classes per week without an awareness of the potential negative impacts upon their health. OA, free radicals, etc.
I was brought up and trained in an athletic climate where extreme, hard-core athleticism was considered the key to good health. It's often abusive to the body.
I am thankful there is more awareness now.
