What if I am physically unable to exercise due to a medical condition?

There is virtually no medical condition that will keep you from doing any type of exercise. Even people with heart failure who were long told not to exercise at all -- can benefit from moderate amounts of activity.

And people with limited mobility can often do water exercises, or do yoga or other exercises while seated in a chair .Of course, if you have any medical condition, check with your doctor before starting any exercise program.
