Muscle strength exercisers designed to provide resistance to muscular contraction in the lower limbs using a mechanism based on a system of pulleys and cables or levers. These exercisers usually consist of a stand-alone machine with weights stacked on top of each other or a hydraulic mechanism, a system to transmit the force (i.e., to convey the resistance), and lever bars or pulley cables on which the user exerts force to counteract the exerciser resistance. These exercisers are used to exercise the lower-limb (e.g., squat, lunge, leg press, leg extension, heel raise) muscles. Lower-limb strength exercisers are intended to improve muscle strength in the lower limbs (e.g., buttock, thigh, calf, ankle); increase muscle size, endurance, and power; and improve bone density. Dedicated lower-limb strength exercisers are available for leg extension, leg press, and leg curl.
