Aerobic exercise

The word aerobic literally means “with oxygen” or “in the presence of oxygen.” Aerobic exercise is any activity that uses large muscle groups, can be maintained continuously for a long period of time and is rhythmic in nature. Aerobic exercises utilize oxygen as the major fuel for sustaining activity for relatively long periods.
Aerobic exercises fall in two categories:

Low to Moderate Impact aerobics – These include walking, swimming, stair climbing, step classes, light water aerobics, rowing and cross-country skiing. Nearly anyone in reasonable health can engage in some low- to moderate-impact exercise. Brisk walking burns more calories than jogging for the same distance because it takes more time to walk than jog that distance and poses less risk for injury to muscle and bone.

High-Impact aerobics – Activities that belong to this group include running, dance exercise, tennis, racquetball and squash. High-impact aerobics should be performed on alternate days. People who are overweight, elderly, out of condition or have an injury or other medical problem should do them even less frequently and only with clearance from their doctor.

Aerobic exercise is good for weight loss because it uses more calories than other activities and helps raise your metabolic rate.

This helps your body burn calories at a faster rate. It is an effective way to lose fat only if you are motivated enough to do it frequently. Aerobics only burns fat during the workout itself. So if you want encouraging results you need to be able to exercise daily and for longer periods.
