The Hydrorider AquaTreadmill is a unique Aquatic Treadmill made out of marine stainless steel AISI 316L (rust proof) The Hdrorider AquaTreadmill platform is made of 308 rolls that are rotating over flexible shock absorbing supports. There is no mechanic resistance nor motor moving the rolls. The user has to move actively the legs impressing a force/movement toward the back contrasting the water resistance while the foot is sliding over the rolls, and again back to the front recalling the leg and starting a new step with the other leg. Walking and running has few side effects besides those provoked by the body weight, witch, sometimes, can become an excessive load for the joints and spine. Lets enter in the water now! We will dramatically reduce the weight effect on our body improving balance, muscular perception and blood circulation.
