Abstract

An exercise fitness machine is configured for vertical lift exercises. Resistance is provided by a fan-flywheel arrangement, with flexible inextensible cables connected to the ends of a horizontal barbell member such that a vertical lift motion rotates the fan-flywheel to create a greater force on the concentric exercise phase, but a reduced force on the return or eccentric phase. This may be configured for shoulder presses, squats, curls, or bench press exercises.

Description

[0001] The present invention relates to a lift-resistance machine in which the exercise training action involves the act of lifting, pulling or pushing a weight bar or handle, and then lowering the bar or handle in a reverse direction, and repeating the motion. The arrangement employed in this invention permits a greater weight resistance to be experienced on the upward or lifting motion than on the lowering or return motion.

[0002] In embodiments of the invention, the weight bar or handle has cables or lines attached to its ends, and the upward motion of the bar pulls the cables and these in turn drive a fan-flywheel, via a system of pulleys and elastic or resilient return mechanisms, so that rotary acceleration plus air resistance provides at least some of the counterforce to motion, rather than gravity alone.

[0003] This arrangement can be used in place of a barbell for presses, squats, curls and similar exercises that typically require a gravity resistance weight like a barbell. This...
