A portable exercise system that can be attached to the uprights on any commonly available training rig, squat stand, or power rack, and for resistance can use any attachable weight. The system includes an upper pulley assembly, a lower pulley assembly and an anchor assembly. The anchor assembly utilizes a wedge and block to set the cable length and is adapted to attach the weights. The upper pulley assembly includes pulleys to keep the cable aligned and the resistance coming from above. The lower pulley assembly could be hinged for an additional degree of freedom. The cable runs through the lower pulleys, to the upper pulleys, and down to the anchor and weights. The other end of the cable has a fixed loop for attaching a handle for the user.

A treadmill has a front or rear set of pulleys and a looped running belt. The pulleys rotate with the movement of the belt, e.g., when a user walks, jogs, or runs on the treadmill. The pulleys are mounted on a rotating roller tube so that the roller tube rotates with the pulleys. The roller tube is mounted on a stationary shaft using bearings on each side and a one-way device that allows the pulleys to rotate in one direction. The rotation direction corresponds to the movement of the top of the belt from the front to the rear of the treadmill. The one-way device prevents the pulleys from rotating in the opposite direction, preventing the top of the belt from moving from the rear of the treadmill to the front. The one-way device may be a sprag clutch. The treadmill may be a motor-less, curved treadmill.

This invention is embodied by a controlled, variable tension line, payout reel machine. A system of sensors detect line tension and line distance paid out, location, and transmit through wired and unwired communication to a microprocessor. The microprocessor is co-located with the reel structure, which in turn applies, via a brake feature, resistance to the reel which is paying out the line being pulled by the user. This invention pertains to all applications where it is desirable to control the tension in a line paid out from a reel or reel. As stated, the payout motive force is supplied by the person, animal or apparatus attached to the end of the line, opposite the reel. The invention applies to the field of precise and measured control of line tension for sport, sport training, performance testing.

An exercise machine system that allows for completion of a plurality of exercises on one machine is disclosed. The exercise machine system includes a frame having a front bar and a base with a first cross bar extending therebetween; a weight attachment bar pivotally attached to the first cross bar via a pivot joint secured to the first cross bar, the weight attachment bar extending to a weight end; a triangular frame extending from the front bar; a second cross bar extending from the base and coupled to the triangular frame; a body support positioned above the triangular frame, the body support having one or more pads to allow for supporting a person thereon, the body support having one or more bars configured to removably couple to the body support; a leg support secured directly to the body support, the leg support having one or more pads; a cable having a first end and an opposing end; a first pulley secured directly to the leg support via first anchor; and a second pulley secured directly to the weight attachment bar via a second anchor.

An exercise system includes a frame, an upper body carriage, a lower body carriage, a positioning carriage, a resistance assembly attached to the frame, and a connecting mechanism. The frame includes a right guide rail, a left guide rail, and a central guide rail disposed between the right guide rail and the left guide rail. The upper body carriage includes an upper right and an upper left carriage slidingly attached to the right and left guide rail, respectively. The lower body carriage includes a lower right and lower left carriage slidingly attached to the right and left guide rail, respectively. 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 rowing exercise device comprises a support structure; a movable user support movably associated with the support structure for movement relative to the support structure; a movable foot support movably associated with the support structure for movement relative to the support structure; a handle; and a rowing assembly operatively associated with the handle and at least the movable foot support to cause at least the movable foot support to move relative to the support structure with movement of the handle so that both a user s body and one or both feet move relative to the support structure with movement of the handle.

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 workout system is provided that includes a piece of furniture having at least a backrest and a seat. A chair workout machine is provided coupled to the piece of furniture. The chair workout machine includes a support frame coupled to at least one structure of the piece of furniture. At least one rotatable arm is rotatably attached to the support frame. One or more resistance elements are coupled to the at least one rotatable arm, where the resistance elements arranged to provide resistance to movement by at least one body part of a user.

An exercise device of the type including a frame with a first crank assembly rotatably coupled to the frame about a first axis and a second crank assembly rotatably coupled to the frame about a second axis. A control system may be used in communication with the first crank assembly and the second crank assembly, which may provide a synchronous movement of the first crank assembly relative to the second crank assembly. A pedal arm may be provided with a first end pivotally coupled to the first crank assembly and a pedal positioned on a second end. A crank link may be used with one end coupled to the second crank assembly and a second end coupled to the pedal arm. The crank link may be movable on the pedal arm which may provide varying paths of motion of the pedals.

A safety signal is sent to a relay coupled to a plurality of power leads of a motor wherein a default state of the relay is to short the plurality of power leads together and wherein the safety signal maintains the relay in an open state. The safety signal to the relay is deasserted in response to a determination that an unsafe condition has occurred.
