leg-extension-unitThe Leg Extension Unit facilitates functional full, body movement sequences that strengthen upper/lower body coordination, and hand/foot coordination. Contra-lateral movement sequences in various planes increase functional strength and stability at all joints. A unique, patented, cam mechanism allows the leg to elongate, as it extends. So, the hip and knee joints are able to move in a fluid, natural range, without compression, increasing stability and strength around those joints. Hand/foot straps, and lightweight aluminum Wing Master accessory are used.
