Aqua jogging, or water running, has long been use as a therapy for injured runners or as a substitute for running or jogging on land. The buoyancy of water when running can reduce stress on the joints of the lower extremities by 90 percent. By adjusting the intensity of the workout, athletes can maintain cardiovascular fitness with minimum stress on their bones and joints. Deep-water running is usually done with some type of flotation belt. However, there are advantages to aqua jogging without a belt.
