ABSTRACT:
An improved exercise machine is revealed, consisting of an air spring added to standard weight training incline benches. The air spring provides positive resistance to the muscles used to push the weight up the incline. The positive resistance to movement supplied by this device has been shown to increase the strength of fast-twitch muscles when exercising.
