A device for an exercise apparatus includes a linear adjustment system and a sensor coupled to the linear adjustment system. The exercise apparatus includes a loading interface and a frame coupled to the loading interface for performing an exercise. The linear adjustment system fixes the loading interface of the exercise apparatus at any one of a plurality of functional positions in a functional range of the loading interface. The sensor measures the force exerted on the linear adjustment system. A correlating mechanism is used to correlate the force exerted on the linear adjustment system with the force exerted on the loading interface. The device allows exercisers to exert high or maximum loads in any one of a plurality of positions throughout their entire range of motion without first passing through a weak range of motion.

An exercise machine for performing a leg press exercise includes a resistance device and a plate configured to receive a user's feet during the leg press exercise. An adjustable resistance attachment device is mechanically coupled to the plate and is be selectively coupled to an adjustable resistance attachment device. One or more cables mechanically couple the adjustable resistance device to the resistance device to define a resistance ratio. Attachment of the adjustable resistance device to the adjustable resistance attachment device results in an increase of the resistance ratio for the machine.

An exercise apparatus for targeting the hip muscles is disclosed. The apparatus consists of a plurality of supports, a footboard, and a belt wherein elastic bands may be attached to the belt and to the base supports to provide resistance. The apparatus is fully adjustable for targeting muscles of interest, and collapsible for ready transport. Adjustable handles are optionally provided to maintain user stability and thus maximize the effectiveness of the exercise. A method of using the exercise equipment is also provided.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

A rehabilitation and exercise system can include a base. A static device can be coupled to the base and configured to provide isometric exercise for a user by receiving static force from the user to facilitate at least one of osteogenesis or muscle hypertrophy for the user. In addition, a dynamic device can be coupled to the base and configured to provide a dynamic exercise for the user by being moved by the user to facilitate at least one of osteogenesis and muscle hypertrophy for the user.

A leg press exercise machine, including: a main frame with first and second rotating bars connected thereto; a support assembly connected to each of the first and second rotating bars, wherein rotation of the first and second rotating bars causes the support assembly to move with respect to the main frame; a seat support bar; and a seat mounted onto the seat support bar, wherein the support assembly holds the seat support bar at a downward angle and wherein the rotating bars are disposed at an angle from 0 to 30 or about 20 degrees to the vertical when the machine is in its rest position.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

A permanently affixed and travelling selector pin, car and weight plate selection mechanism for use with physical fitness equipment is disclosed including a segmented track and/or cut out cavern within the plate body for the car to travel within in either vertically or horizontally in order to select a different weight plate or cumulatively, more or less weight for an exercise. The selector pin and car mechanism features a selector pin which is not removable from the car and is inserted through the car which is contained by the track and or plate body shape and into a throughbore in the weight plate in order to engage with the selector stem.

A locking device for an exercise system may include a locking member having a contact portion and configured to move between a first position and a second position. When in the first position, the contact portion of the locking member is not in mechanical communication with the resistance mechanism of the exercise system, thereby allowing movement of the at least one moveable assembly. When in the second position, the contact portion of the locking member is in mechanical communication with the resistance mechanism of the exercise system, thereby preventing movement of the at least one moveable assembly.

A physical exercise device providing a stepper like motion for a user may include a pair of foot pedals and a pair of arms for engagement by the user while seated on the seat of the physical exercise device. The pair of foot pedals and the pair of arms may be connected to a drive train which provides contralateral motion between the pair of arms and the pair of foot pedals. A pedal and arm lock mechanism may also be provided which prevents the pedals and arms to be moved in a lock state, while allowing movement of the pedals and the arms when in the unlock state. The physical exercise device may also include computational and data acquisition units for receiving a position signal and pedal force signals and recording the signals.
