Aqua Fitness and Aqua Gym is considered a complex sport that absolutely works all muscle groups, combining movements of arms and legs (borrowed from aerobic programs) which runs in medium depth water, background music and sometimes auxiliary equipment.
In addition to the benefits of any physical activity, performing water aerobics exercises ensure complete protection of joints and tendons due to the phenomenon of buoyancy (water supports 90% of body weight, or in other words, gravity is much lower in the water than on dry). So, exercise can be performed safely by anyone, including the elderly.
