Dancing is perhaps the second most enjoyable form of exercise.While all forms of dance -classical Indian, ballet, disco etc, undoubtedly involve aerobic exercise, the term "aerobic dance" refers to rhythmic activity designed to exercise systematically all the major muscle groups. Although aerobic dance to a stirring beat can be just as much fun as disco or the tango, the primary goal here is safe and effective exercise, not artistic self-expression. You can move to the beat of a TV exercise program or to an old Jane Fonda workout video in the privacy of your home, but taking part in group classes under the watchful eyes of a trained instructor will not disappear in a flash when the power goes out. Exercise that emotionally engages you in more likely to make you cross your body's limits without your realising it, so first warm-up and stretch to expand those limits. You will need very little equipment for aerobics: good shoes, an even, preferably carpeted surface, "breathable" apparel, a step platform, and music of around 120 beats per minute. Low-impact dancing is best for beginners, the obese, pregnant women and the elderly for whom jumbing in the air is a big no-no. Low impact exercise involves a trade-off that sacrifices intensity for safety.One way to maximise the exercise value is to increase the range of movement and to exercise for longer: lift the leg higher, swing the arms in a wider arc, hold the body part against gravity for longer, etc. Dancing that incorporates hopping and jumping is best for those looking for a great cardiovascular workout .if you suffer from back trouble, arthritis or cardiovascular conditions, resist the temptation to join in. Ask the instructor to demonstrate a low impact version you can perform to the same beat.
