Abstract: A multi-axes exercise machine for strengthening muscles surrounding shoulder joint of a user allows the user a range of motions about lines of motion perpendicular to an arc of circumduction of the shoulder joints. A pair of handholds is suspended from an arcuate guide plate, which extends above a user station. By moving the point of securing the handholds along the length of the arcuate guide plate, the user can re-position the upper ends of the handholds from a location above the user station to a position behind the user station. At all times, the axes of rotation of the handholds are parallel to each other and extend along a plane that contains the axis of circumduction of the user's shoulders. A centerline of each handhold passes through the center of the corresponding glenohumeral joint of the user during the exercise.

Abstract: This is a multiple function exercise device that enables simultaneous exercise of several muscle groups. The device includes a chest pad that is stationary to the support frame and a seat that moves in a path of motion that enables the user's chest to remain on the chest pad as the user's legs are extended, thereby causing movement of the seat. This combination provides activation of the leg and hip extensor muscles and the trunk flexor muscles at the same time. In another embodiment, a resistance arm is added that is pivotally attached to the frame and mechanically linked to the seat, thereby causing movement of the arm as the seat moves. This allows the additional activation of the triceps muscles, or elbow extensors of the upper arm, while also working the leg and hip extensor muscles and the trunk flexor muscles all in a single movement. The advantage to such a movement is the time saving effect of working a large group of muscles at one time as opposed to several exercises one after the other.

Attached to the shaft is at least one weight arm and at least one work arm. The work arm can be releasably connected and take multiple forms, each adapted for particular exercises.

Abstract: A weight lifting machine is useful for developing muscles used in arm wrestling. The weight lifting machines comprises a carrier that rotates about an axis of rotation. Pivotable levers are connected to the carrier symmetrical about the axis of rotation. A cord hangs from each lever. The cords join into a single cord that holds a weight so as to produce equal and opposite torques on the carrier. A person exerts a force on the carrier sufficient to overcome one of the torques and thereby rotate the carrier. By pivoting the levers the cords hang at different distances from the carrier axis of rotation, thereby changing the amount of torque produced on the carrier by the weight and the amount of force the person must exert to rotate the carrier. A block on the carrier contacts the cord during carrier rotation in a manner that results in a smooth and continuous resistance by the weight on the person's arm.
