The OnTrackYou Sky Climber is a great variation of the Horizontal Ladder which provides for a wide variety of griping positions. It develops the type of strength required by rock climbers who use their upper body for dexterous holds and pulls on the mountainside.
In addition to strengthening grip and forearm strength, the equipment engages a variety of upper body muscles, such as the trapezius, latissimus dorsi, and biceps.
