The Aqua fitness kit is a great way to enjoy a pool and experience a novel way of exercising. The buoyancy of water means there is less impact and strain on joints, while the natural resistance of water is higher than that of air, which means muscles have to work harder for even the simplest of movements. This can help to improve muscle tone and endurance. The fitness kit includes: 2 dumbbells, waist belt and 2 gloves, Chlorine-resistant EVA foam aqua belt for buoyancy and support, Comfortable neoprene gloves.
