Abstract

Embodiments of a strength training apparatus and related methods are provided. In one embodiment, the strength training apparatus includes a base member and a tower structure coupled with the base member. At least one arm is pivotally coupled with the tower structure. A flywheel and a cable and pulley system are associated with the at least one arm, wherein displacement of at least one cable of the cable and pulley system effects rotation of the flywheel. The strength training apparatus may include a selectively adjustable magnetic braking mechanism associated with a flywheel that is configured to apply a selected resistance to the rotation of the flywheel. A torque sensor may be associated with the flywheel and the measured torque during operation of the apparatus may be used to calculate the work expended in rotating the flywheel. In one embodiment, the calculated work may be expressed in units of watts.
