Weightlifting & Exercise/Exercise and health


I am 65 year old male, married, one child. No smoke, no drink. I got really sick a year ago. 7 months in bed. No exercise. Then I joined a gym. First time; once for 15 minutes. Exhausted. Second week; two times. 15 minutes each. Had to hold onto the machines just to walk from a, to b. Now I am going twice a week, 1 hour each time. Increased my lifts from 10 lbs, to now; 30 lbs. Slow reps. But a few more reps each time. Some pain when I went home. But no pain afterwards; especially the next day. Which is a good thing. But I do not understand HOW exercising makes the body healthier. I hold less onto the machines when I walk. I feel better. Look better. Confused as to how exercising changes the body. Any thoughts?

Hi Dave,

The body is a marvelous creation that actually responds to small bouts of exercise which actualy cause microtears and slight damage to the muscles. The body is programmed that whe it is hurt it will try to heal itself. When it heals itself from bouts of exercise it actaully increases its strength so that the next time the same amount of exercise will not cause as much damage. You will find that even 80 and 90 year old nursing home patients respond to resistance exercise and become stronger.

Basically the exercise causes a small amount of muscle damage that the body heals. When the body heals the "damage" done by exercise it increases the strength of the muscle, when the muscle is made stronger the body is more healthy and stronger. While muscle is actually built during rest, the exercise is needed to cause the damage so the body can heal it stronger.

I hope that all makes sense.

Hope this helps

Have agreat day
