A successful exercise program involves frequent physical activity
that is rhythmic, repetitive, challenges the circulatory system, and
uses large muscles. The exercise program must significantly increase the
blood flow to the muscles for an extended period of time, promoting
cardiovascular fitness. Such exercises are called isotonic, dynamic, or
aerobic. If you want to have a healthy heart, you need to perform
aerobic exercise.
Aerobic activities really "get the blood pumping." As the heart beats faster, the blood circulates more quickly, delivering extra oxygen to the muscles. This builds strength, or cardiovascular fitness. Some recommended aerobic activities are walking, hiking, jogging, bicycling, swimming, jumping rope, and roller skating. Some forms of exercise, like weightlifting, can build muscle strength without building cardiovascular fitness.
