An exercise system includes an exercise platform comprising an internal motor coupled to a cable exiting the exercise platform via a portal in an exit direction to transmit force to a remote handle. It further includes an auxiliary pulley external to the exercise platform that redirects the cable from the exit direction to facilitate a direction of an exercise motion.

An adjustable reformer for exercising is provided. The reformer includes a frame, a carriage slidably mounted to the horizontal frame, and at least one resistance element connected to the carriage. A cord connects the carriage to at least one lower guide and at least one upper guide. Pulling the cord causes movement of the carriage along the frame against resistance provided by the resistance element. The guides can be height adjustable. The reformer can include a cord retraction system. Related methods of exercise are also provided.

Embodiments of a strength training apparatus and related methods are provided. In one embodiment, a strength training apparatus may include a tower, a first arm and a second arm each pivotally coupled with the tower and each being configured to be selectively positionable independent of each other at multiple angles relative to each other, a first pulley coupled to an end of the first arm, a first cable extending through the first arm and the first pulley, a second pulley coupled to an end of the second arm, a second cable extending through the second arm and the second pulley, a magnetic mechanism coupled to the first cable and the second cable and configured to provide multiple levels of resistance to a user pulling on the first cable and/or the second cable, and a control panel located on the tower.

An endless rope trainer that includes an upright frame, a drive roller supported a distance above ground on the frame, an endless rope entrained around the drive roller, and a means of applying resistance to rotation of the drive roller. A pair of guide rollers are provided proximate the drive roller. The guide rollers pivot together as a unit about the axis of the drive roller independently of the drive roller for maintaining a constant wrap angle of contact of the endless rope on the drive roller regardless of pull angle on the endless rope.

An exercise assist apparatus may include a frame and a cam assembly pivotally connected to the frame. A cable having one end fixedly secured to the frame may extend over a traveling pulley operably connected to the cam assembly and about a fixed pulley connected to the frame. One or more flexible progressive resistance bands may provide substantially linear assistance/resistance throughout an exercise.

A strength training machine includes a first motor oriented at a first angle relative to a chassis. It further includes a second motor oriented at a second angle relative to the chassis. The first and second angles skew the motors with respect to each other.

A fly wheel resistance workout system is provided. One embodiment includes a plurality of braces secured into at least one of a floor surface and a wall surface, wherein each one of the plurality of braces on the floor surface or the wall surface is located at a predefined location on the floor surface or the wall surface; a removeable anchor that can be releasably secured to one of the plurality of braces such that the removeable anchor is secured to the floor surface or the wall surface at a location of interest; a grab bar that is grasped by a user during an exercise motion; a fly wheel resistance device that opposes the exercise motion made by the user; and a strap with an end that is coupled to the fly wheel resistance device and with an end that is coupled to the grab bar.

A muscle toning device, attached to a chair, underneath the sitting surface of the chair, comprising: an exercise resistance device storing an elastically extendable, elongate resistance element; a user handgrip means, the elongate resistance element being attached at its second distal end to the user handgrip means; at least one guide comprising a first bearing and guidance channel, for locating and guiding the elongate resistance element; characterised in that the muscle toning device further comprises at least one second bearing, about which the elongate resistance element turns, wherein the second bearing is laterally translatable, the laterally translatable bearing being anchored to the exercise resistance device by an elastically expandable attachment means, such that when a pulling force is applied to the elongate resistance element, the laterally translatable bearing is caused to move in the direction of said pulling force.

An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.

A weightlifting machine that includes a pulley system and a cable system that attaches to a weight rack frame to allow a user to perform a weightlifting exercise. The pulley system may include a first pulley and a second pulley where the cable system engages each pulley. The cable system may have a first end connected to a grip attachment and a second end attached to a resistance element. The resistance element may include a resistance band, a weight support that holds a weight plate, a set of weight plates, or other type of resistance element. The cable system may extend from the pulley through an opening located one of the frame members that form the frame.
