The Cybex seated Leg Curl has a specific innovative design positioning the tibia pad an intuitive, virtually effortless, one button adjustment resulting in easily accessible and easily adjustable machines. Offset input arm allows for the lower leg pad to adjust with minimal effect on the starting angle of the knee. In combination with proper pivot location, this allows the use of a contoured pad for improved comfort.The angled back pad (100 degree angle between seat and back) is wider than most leg curl machines and is designed to relieve hamstring tension. The four-bar linkage combined with gas spring assist means the seat back position can be adjusted without requiring the user to get off the machine. Position indicators enable users to perfectly duplicate their position on the machine each time they use it. The thigh stabilization method used on Cybex provides significantly reduced strain on the knee compared to other methods.
