Wear proper shoes and clothing and drink water before, during, and after exercise. At the end of your physical activity, cool down by decreasing the intensity of your activity so your heartbeat returns to normal and be sure to stretch muscles. If your chest feels tight or painful, or you feel faint or have trouble breathing at any time, stop the activity right away and talk to your health care provider.

If your feet or joints hurt when you stand, non-weight-bearing activities may be best for you. Such activities include swimming or water workouts, and they put less stress on joints because you don't have to lift or push your own weight. Pat yourself on the back for trying, even if you can't complete the workout the first time. It may be easier the next time --- so try again! Remember, moving any part of your body --- even for a short time --- can make you healthier.

Choose a variety of fun activities, so that you don't get bored. Even housework, gardening, doing yard work, or walking the dog gets you moving. If you can't set aside one block of time, do short activities during the day, such as three, 10-minute walks. Create opportunities for activity, such as parking your car farther away, taking the stairs instead of the elevator, or walking down the hall to talk to a co-worker instead of using e-mail.

Don't let cold weather keep you on the couch, but do exercise to a workout video, join a sports league, or get a head start on your spring cleaning by channeling your workout energy into cleaning out closets or washing windows. Vary your walking route to stave off boredom and exercise with a friend or family member for company. If you have children, make time to play with them outside. Set a positive example!
