For profuse sweaters and those suffering from joint pain, the underwater 'Aquabilt Treadmill' is for you. The motor-less design has been built to operate electricity-free underwater, providing a cool and comfortable calisthenic experience.
The Aquabilt Treadmill is light at compact as far as moving belt gym equipment goes, enabling easy maneuvering in and out of the pool. An unusual-looking apparatus at first, this underwater treadmill actually provides quite an effective workout. It involves a decent amount of water resistance that makes your legs work harder, despite it being a low-impact activity.
