I recommend exercise highly for all of my patients. There's almost no one, regardless of age, who can't benefit from starting an exercise program. Studies have even shown functional benefits in people over ninety who strengthen their leg muscles in a six week exercise program. However, if you intend to pursue vigorous exercise and you're over forty or have health problems, have an examination with your doctor . But vigorous exercise is not required to improve your health and well-being.
Daily walks are a great form of exercise and often the easiest form of exercise for many people.
Even the busiest among you can probably do some stationary bicycling, even if you need to be on the telephone or reading while you're on the bike. The key thing is to start exercising and to find the right types of activity for you.
