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.

An exercise machine component comprises a cable connection base adapted to attach to an end of a cable, a chamber adapted to receive a key through an opening of the chamber, a biasing mechanism within the chamber, and a receiving groove within the chamber wherein the biasing mechanism biases the key against the receiving groove so that the key is securely fixed within the chamber.

An exercise apparatus having a stationary frame, a handlebar assembly, a frontal-torso assembly, a resistance assembly, a rotatable crankset having a pair of crankarms with pedals mounted thereon where the crankset is positioned rearward of the handlebar assembly and the frontal-torso assembly.

A linear powered input device that utilizes linear input from a user and converts the linear input rotational energy to perform work. The linear input is generated by lever arms having a slotted attachment at a pivot point that allows a free end of the lever arms to move linearly rather than in an arcuate path. The lever arms are connected to a power transmission mechanism that wraps around one or more drive wheels having one-way bearings mounted on one or more output shafts. The output shafts can be connected to any type of auxiliary device to perform the desired work. Output wheels may be mounted on the output shafts and operatively connected by a transmission link that allows linear motion of any lever arm in any allowable direction to cause the output shaft to rotate in the same rotational direction so as to receive continuous input.

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.

An exercise machine may include a frame, a resistance mechanism supported by the frame, first and second pull cables supported by the frame and linked to the resistance mechanism, a power rack attached to the frame, first and second handles selectively attachable to the first and second pull cable, and first and second pulleys. The power rack includes upright posts configured to have barbell holders adjustably attached thereto such that the barbell holders are configured to be adjusted in various positions between highest positions and lowest positions on the upright posts. The pulleys are configured to selectively receive the pull cables to enable the pull cables to be selectively attached to a barbell to assist or hinder a user in lifting the barbell in a combined cableand free weight workout, the pull cables decoupled from the pulleys for cable workouts.

A controllable tension force is provided on a first cable. The first cable has a terminal end wherein the terminal end is adapted to attach to an accessory. The first cable is coupled to a motor. The first cable and motor are part of a resistance unit. The resistance unit is coupled to a user support unit having a sliding seat.

An adapter assembly for releasably connecting an accessory connector to an exercise rope is provided. The assembly comprises a connection part being formed by a first portion and a second portion, each having a bottom end and top end, wherein the first and the second portion of the connection part forms, at its bottom end, a cavity configured to receive an end portion of said rope, and wherein the top end of the connection part is configured to releasably connect the accessory connector.

An exercise device and a method for its use to aid in the correction of Anterior pelvic tilt. A base has an upper support and a lower support. The base device is strapped around a user's stomach and connected to a rope. The rope passes through the user's legs and is attached to a weight holder behind the user. As the user walks forward, the weight holder is dragged along the floor and the force of the weights on the weight holder pressed the base against the user's stomach and aids in proper alignment of the pelvic region.
