Abstract: A chest press machine having a pair of converging exercise arms rotating around an arm pivot axle. Subsequent circular motion causes user's elbow extension to decelerate through the stroke. The direction of resulting force at start position is normal to direction of the resulting force at end position. A sweep arm attached to the exercise arm is attached via cords to some form of resistance. Changing leverage is exerted on the exercise arms as they rotate, thus counteracting the increasing difficulty of the stroke due to decreasing involvement of the tricep muscles. Attached to each exercise arm a hand-grip where gripped area rises from the horizontal to allow lateral movement of wrist through the stroke. The radius of the circular motion is adjusted by the telescoping hand-grip. As the exercise arms are pressed and squeezed together, the upper arms horizontally adduct, the elbows joints extend, and wrist joints move laterally.
