Aquajogging is a water sport and activity. Unlike a swimmer, an aquajogger moves in the water in an upright position. A purpose-made buoyancy belt is usually used to help maintain the position. Aquajogging is often done in a swimming pool.
Aquajogging started in America as an exercise method for pre- and post-surgery patients. It has proven a suitable form of exercise for elderly people and overweight people because of its low impact to the joints and its effectiveness due to the water resistance. This combination avoids muscle soreness, stress fractures and aching joints. From the start of the 21th century, aquajogging has been increasingly popular as physical exercise and even competitive sport, outside its therapeutic use.
