Readers Digest "Live Longer Cookbook" states that psychological tests have shown that regular exercise results in greater self confidence & morale. Aerobic exercise (not just what is commonly called aerobics) is seen as improving one�s sense of overall well being, in part by reducing anxiety & depression. 

    Exercise in part turns back the effects of time & increases our life span. There is some question as to whether some aging symptoms such as fatigue & hypertension are related in part to inactivity.

    Studies have shown that aerobic exercise (giving your heart, circulatory system & lungs a workout via sustained movement of the large muscle groups) combined with strength training (weight lifting & isometrics) is especially effective. It is especially important to consult your doctor before beginning if you are over 35, have been inactive for some time, or have risk of heart disease.

    Many activities can be turned into an aerobic workout by continuing briskly for at least 20 minutes. 5 minute warm-ups & cool downs are important.

    Find an exercise specialist to teach you how to use weight lifting equipment properly. Begin slowly. Begin your routine with the large muscles of the lower body before working the smaller muscles of the upper body. Take at least 2 seconds to lift a weight & 4 seconds to lower it. Space workouts at least 2 days apart.

    Stretching exercises & isometrics (pushing or pulling against resistance) can be helpful for arthritis & osteoporosis as it helps stabilize painful joints. Swimming is recommended for endurance. Some weight bearing exercises & aerobics strengthens bones & stimulates the production of hormones that help protect them. There are indications that especially aerobic exercise helps modify the loss of bone mass.

    Improved fitness will lower your heart rate. The fewer beats per minute, the less wear & tear on the heart. This happens because your heart has become stronger & therefore can pump more blood per beat.

    It is never too late to start an exercise program.
