Most Important Age to Exercise

Is it more important to exercise when you are young or when you are old?

Studies have shown that Harvard and University of Michigan varsity letter-winners do not live longer than their less-athletic classmates, but people who exercise regularly as they age live three to seven years longer than non-exercisers. Other studies show that athletes are no lower risk of heart attacks later in life than their less athletic peers UNLESS they continue to exercise as they age. Former athletes who continue to exercise have lower blood levels of the bad LDL cholesterol, total cholesterol, triglycerides and higher levels of the good HDL cholesterol that prevents heart attacks.

It's called reversibility. Every benefit gained by exercising is lost soon after you stop. Muscles enlarged by lifting heavy weights return to their previous size within a few weeks after you stop lifting. People who do aerobic exercise lose their slow heart rates and greater endurance soon after they stop regular workouts.

Regular exercise is the most effective way to prevent the gradual weight gain that often comes with aging. If you're tired of being out of shape, check with your doctor. Then pick a continuous sport that you will enjoy doing, such as walking, swimming, cycling or dancing. Start out by exercising slowly and comfortably until your muscles start to feel heavy or hurt, and then stop for the day. Do this every other day and gradually increase the time you spend exercising, always stopping when your muscles feel heavy or hurt. When you can exercise continuously for 30 minutes, three times a week regularly, you are fit and don't need to do more unless you want to.
