Because water is denser than air, it provides excellent resistance to the moving muscles without the full weight of your body during an exercise. The resistance of water can be further complimented by adding Special Aquatic Resistance training equipment like Push Plates, buoyant dumbells, hand held helmets, foam rollers etc. In addition to this, a motorized wave generator also helps in increasing the turbulence and resistance of the water increasing the complexity of the workout.
