An exercise machine monitoring and instruction system for the movement of an element of an exercise machine by an exerciser and providing automated feedback to the exerciser to help improve the exercise in real-time. The exercise machine monitoring and instruction system generally includes an exercise machine having a movable element that moves between a first position and a second position in a reciprocating manner, a sensor that detects a real-time position of the movable element, a processor in communication with the sensor to receive the real-time position data from the sensor related to a position of the movable element and a feedback device in communication with the processor that provides real-time instructions to the exerciser on how to adjust their workout to achieve a desired result.

A device for use with an exerciser device, such as a reformer, which permits the adjustment of a resistance system, even when connected to a resistance source, by selectively relieving the resistance force imparted on the resistance adjustment system when changing the resistance and automatically reengaging the resistance force when exercising. A strain relief is coupled to a linkage between the resistance source and the resistance adjuster. When engaged, the strain relief selectively reduces the resistance force transmitted through the linkage to the resistance adjuster to permit movement of the resistance adjuster relative to the purchase. When disengaged the strain relief permits transmission of the resistance force through the linkage to the resistance adjuster.

An extendable fitness bar including an internal elastic member. The device includes two, hollow external bars with ends facing one another. On the interior of the two external bars is an internal bar and an elastic member that extends through the two external bars and the internal bar. The elastic member is attached to the far end of the first external bar and the second external bar. The user can grasp each external bar and separate them, exposing the interior bar and creating a longer continuous bar. This separation also causes the elastic member to stretch creating tension. The user may also twist the two bars in opposing directions (clockwise and counterclockwise) for additional stretches.

A dynamic exercise device having a hand grip mounted in an inner ring, the inner ring mounted in an outer ring, and the outer ring mounted in a base. Each of the above elements is movable in at least one degree of freedom relative to each of the other elements. Optionally, the base has feet. The feet may be fixed elements that provide immobility, or dynamic elements, such as roller bearings, that may provide adjustable movement.

An exercise including a horizontal rail having a proximal end and a distal end. The rail is supported at a height by two or more vertical supports at the proximal end and distal end. A fixed member is positioned at the proximal end of the rail and have a pair of handles and a pair of arm support, wherein the positions of the pair of handles correspond to the positions of the two arm supports. The exercise apparatus includes a slide member slidably mounted to the rail and slide between the distal end and the fixed member. A user can kneel on the slide member while gripping the two handles and having the arms supported by the two arm supports. Once in position, the user can pull the slider member towards the fixed member against the resistance of a resistance mechanism.

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.

A reformer exercise apparatus is disclosed that has a generally rectangular frame, a carriage movably supported on the frame, and a foot support member supported by the side rail portions of the frame. The foot support member has an inverted U shape carbon fiber tube having ends each fixed to a foot bar support member having a cylindrical base, a cylindrical post welded to the base, and a foot bar support arm welded to one end of the cylindrical base, for connection to a foot support assembly operable to selectively position the foot support member at various positions along the side rail portions of the frame.

An exercise device accommodating leg thrust exercises is shown and described. The device provides a flat, nominally planar base or frame on which are mounted two slide members riding in parallel, linear tracks. Each slide is coupled to the frame by an elastic tether. A hand grip bar spans right and left sides of the frame at one end thereof. In use, a person grasps the hand grip bar, and places each foot on one of the slide members. The user then pushes with either one leg or alternatively, with both legs, against the resistance of the elastic tether.

An exercise system that may be rail-less, frameless, and/or portable is described. The exercise system includes a carriage having a plurality of wheels and a stationary platform. The stationary platform is independent of and separate from the carriage, and the stationary platform is freestanding. At least one tension member having a first end is attached to the carriage and a second end is detachably attached to the platform such that the carriage is movable on a horizontal plane parallel to a ground surface while the stationary platform remains in a fixed position.

A running device and method of using the device are disclosed. The device may include a moveable material within an inner chamber of the running device's housing. In operation, a running device may be held in each hand and the runner may thrust both hands downward prior to landing and quickly bring the devices to a vertical stop after landing. Bringing the devices to a vertical stop may cause the moveable material to collide with the housing and increase the force exerted by the runner on the ground. A delay component may delay the peak force exerted by the material against the housing so that the translation of that force to the ground coincides with the peak force that the runner would have exerted against the ground in the absence of the devices.
