These exercises are usually done to rhythmic music. Weights can also be included in the workout. Each workout session runs for about 45-60 minutes. It begins with a warm-up session, which incorporates slow cardio and stretching exercises to get the muscles ready for the increased activity to follow, and ends with a cool-down, where the limbs and other parts of the body are stretched and relaxed. According to estimations, about 500-700 calories are burned in a whole session.

Besides, if they have not been exercising, conventional aerobics done on land can be pretty tough on their aging bodies, increasing their chances of either injuring themselves or worsening a health condition like heart disease.
