It can also improve sleeping habits, appetites, and moods, she says. Before beginning an exercise program, consult your physician. There are several types of aerobic exercise, not just the bouncing and prancing around you often see on television. Walking, running, bicycling, and swimming are also considered aerobic exercise.

Older adults often drop out of classes with both young and old members because of perceived competition. A typical aerobics class runs about 45 minutes and includes warm-ups, aerobics, stretching, and a cooldown, in that order. In addition to aerobic exercise, aim for two sessions per week of strength training. For an aerobics class, a properly fitted aerobics shoe is recommended. These shoes may also be worn for walking, but a shoe primarily designed for walking or running may hold the foot too rigidly for aerobic movements.
