Muscle strength exercisers designed to provide resistance to muscular contraction using a pneumatic mechanism in which resistance changes in proportion to the force exerted on it. These exercisers usually consist of a stand-alone machine with a pneumatic piston, a system to transmit the force (i.e., to convey the resistance), and lever bars on which the user exerts force to counteract the exerciser resistance. Dedicated pneumatic exercisers intended to improve the strength in full body or specific body muscle groups such as the upper and lower limbs, trunk, and neck are available; the exercisers may also increase muscle size, endurance, and power, and improve bone density.
