Vision Keystone Leg Extension / Leg Curl

The Vision Fitness Keystone Leg Extension / Leg Curl combines two essential lower-body exercises into one space-efficient selectorized station. Designed to train both the quadriceps and hamstrings, this dual-function machine is an excellent solution for commercial facilities that want to maximize exercise variety while making efficient use of floor space.

A refined cam profile follows the body's natural strength curve to provide smooth, consistent resistance throughout each movement. Multiple adjustment points, including a five-position range of motion, six-position thigh pad and seven-position back pad, help accommodate users of different sizes. A pivoting ankle pad automatically adjusts for added support, while integrated thigh-pad handles help users maintain stability during both exercises.
