The connecting mechanism mechanically couples one of the upper body carriage, the lower body carriage, or the positioning carriage to the resistance assembly such that the resistance assembly applies a predetermined level of resistive force to the upper body carriage, the lower body carriage, and/or the positioning carriage.

A leg stretching apparatus can be safely used without a risk of damage, with a simple coupling and can be conveniently installed at a site at which leg stretching is desired to enable efficient leg stretching. The leg stretching apparatus includes a fixing plate in which a first fixing plate, which includes a plurality of coupling grooves, and a second fixing plate, which includes a plurality of coupling protrusions corresponding to the coupling grooves, are detachably configured. A fixing part has one end coupled to the first fixing plate and another end equipped with an adjusting part. An elastic string has one end fixed to the fixing part and another end extending in a longitudinal direction of the fixing part, and opposingly branched with two free end portions behind the first fixing plate. A moving part is installed at the second fixing plate to guide the branching of the elastic string.

An exercise apparatus includes a frame and a load mechanism disposed on the frame. The load mechanism has a plurality of selectable weights with each of the selectable weights having an associated indicator device. A press is mechanically coupled to the load mechanism to displace a load based on a selected weight and a sensor is disposed to measure an extent and speed of displacement of the load. A processor is in communication with the sensor, and the processor is configured to determine an indicator signal to send to the indicator device of one of the plurality of selectable weights of the load mechanism based on received performance data, the indicator signal used to indicate which one of the plural of weights to select.

A cradle for supporting an adjustable free weight assembly that includes first and second weight plate sets. End walls and side walls of the cradle define a cavity sized to receive the free weight assembly. The end walls engage plate portions and locking element portions of outermost weight plates of the free weight assembly when received in the cradle. Inboard surfaces of the side walls engage portions of weight plates in at least the first weight plate set to substantially inhibit the first weight plate set from moving vertically or laterally between the side walls. The configuration of the inboard surfaces of the side walls aligns the weight plates in the first weight plate set both vertically and horizontally so that central openings in the weight plates for receiving a selector shaft are substantially concentric.

An isokinetic oscillation exercise device of an elongated flexible blade having a first and second end and a grip portion coupled to a middle portion of the elongated flexible blade. End caps coupled to said first and second ends adapted to storage. Further, a method is disclosed of manufacturing an isokinetic oscillation exercise device that provides a flexible elongated flexible blade, a grip portion injection molding, a pliable ring injection moldings, and end caps injection molding; slides the pliable rings on the elongated flexible blade separated by a length of the grip portion, overmolds a first-shot of the grip portion over the pliable rings, overmolds a second-shot of the grip portion to the first-shot of the grip portion to the elongated flexible blade, seals the first-shot to the second-shot of the grip portion against the pliable rings; and attaches the end caps to the elongated flexible blade.

An end platform for an exercise machine for increased support of an exerciser's spine, neck and head which allows for an expanded scope of exercises that cannot otherwise be performed on the machine without the improved platform. The end platform for an exercise machine generally includes a novel, ergonomically improved stationary platform affixed to at least one opposed end of a substantially longitudinal exercise machine that includes at least a resistance biased reciprocating platform. The improved end platform provides for increased support of exercisers' spine, neck and head, thereby allowing for an expanded scope of exercises that cannot otherwise be performed on the machine without the improved platform, and further provides for the attachment of new and novel exercise equipment accessories to the exercise machine.

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine generally includes a carriage movably positioned with respect to the at least one rail, a plurality of springs selectively connectable to the carriage to provide a resistance level to the carriage, a plurality of electrically actuated mechanical devices adapted to latch a corresponding one of the plurality of springs to the carriage when in the latch state and unlatch a corresponding one of the plurality of springs to the carriage when in the unlatch state and a control unit in communication with the plurality of electrically actuated mechanical devices to selectively control the state of each of the plurality of electrically actuated mechanical devices to be within the latch state or the unlatch state.

An exercise apparatus includes a frame with a pair of vertical guides. A carriage is slidably carried on each of the guides. Each of the carriages has a locking mechanism to lock the carriage at a selected vertical position and a release to disengage the locking mechanism. A horizontal exercise bar is slidably carried on guide rods. First and second cables are coupled to a selectable exercise resistance, each of the cables having an end selectively coupled to either the respective carriage or to a respective bracket at the end of the exercise bar. Secondary brackets on the exercise bar are configured to engage respective ones of the carriage releases and grab the carriage so as to selectively engage and disengage the locking mechanisms upon axial rotation of the exercise bar and raise and lower the carriages with the exercise bar.

A grip exerciser has a first handle, a second handle, a connecting member and a spring. The first handle and the second handle both have a pivoting portion and a holding portion, a pivot is disposed through the pivoting portions of the first handle and the second handle to assemble the first handle and the second handle together; the first handle further has an escaping space at an inner edge for accepting the connecting member, and the second handle further has a closed surface at an inner edge; the closed surface further has a plurality of positioning protrusions located along a continuous line and capable of engaging with one end of the spring;

An exercise device is described which includes a platform having a first end and a second end opposite the first end; first and second wheels, wherein the first wheel is positioned proximate the first end and the second wheel is positioned proximate the second end and the first and second wheels are configured to roll across a surface as the exercise device is displaced along the surface; a first motor configured to apply a first torque to the first wheel where the magnitude of the first torque is related to the distance of the exercise device from a zero position and the direction of the first torque urges movement of the exercise device toward the zero position. Versions are also described with more wheels and more motors.
