Abstract: The subject invention provides a triceps exercise machine which minimizes the torque on a user's shoulders throughout the range of motion. The exercise machine applies a pulling force to the user's arms, the magnitude and direct of which remains substantially constant, such that as the users' hands rotate about the user's elbow the effective toque on the user's elbows and shoulders remains substantially constant.

Abstract: A rowing exercise machine provides a declining, substantially linear path of motion while offering a consistent force angle at the grip. This allows for a fairly consistent torque application at the shoulder joint, throughout the range of motion of the exercise. The exercise machine includes an input assembly which enables a user to maintain biomechanical alignment of the user's wrist and forearm during performance of the exercise, while maintaining a consistent torque applied to the shoulder joint, in the stability of an exercise machine. The input assembly defines a declining, substantially linear path, where the user's forearms remain substantially parallel to the ground as the input assembly is drawn back.

Abstract: The subject invention provides an upper body exercise machine with increased joint range of motion along with more consistently applied torque to the joint throughout the entire range of exercise. The exercise machine includes dual axis, dual hinge mechanisms enabling a user emulate the natural biomechanical motion associated with free weights, while maintaining the stability of an exercise machine and providing more consistent loading than free weights. The dual axis, dual hinge mechanisms permit the handles to be independently or in combination moved longitudinally and laterally in a relationship selected by the user.

Abstract: A leg press exercise machine that provides translational and rotational motion of the user support structure by translating the user support structure along two intersecting non-orthogonal linear paths. A front portion of the user support structure travels along an inclining linear path and a rear portion of the user support structure travels along a declining linear path. The translation of the user support structure along the inclining and declining linear paths results in the user support structure exhibiting a rational motion, defining an arcuate path.

Abstract: An exercise device includes one or more foot supports movable along an arcuate path defined around a point of rotation. The arcuate path is divisible into machine defined user selectable arc segments and the movement of the foot support(s) is limited to the machine defined user selected arc segment. The exercise device can include a frame, a linkage movably engaged with the frame, a foot support movably engaged with the linkage, a crank arm movably engaged with the frame, a motor operative to move the crank arm location with respect to the frame, and a drive linkage movably engaging the linkage.

Abstract: The subject invention provides an upper body exercise machine with increased longitudinal and lateral range of motions. As described herein, the exercise machine contains dual axis, dual hinge mechanisms enabling a user emulate the natural biomechanical motion associated with free weights, while maintaining the stability of an exercise machine. The dual axis, dual hinge mechanisms permit the handles to be independently or in combination moved forward (i.e., longitudinally) and inward (i.e., laterally) in a relationship selected by the user. Consequently, the user can grasp the handles and push forward and inward in the natural actuate path. Alternatively, the user can select another path to give the muscles a different workout.

Abstract: The subject invention provides an exercise machine for exercising the lower torso. As described herein, the exercise machine includes a stabilizer pad, which effectively immobilizes the user's lower body to maintain proper pelvic positioning during execution of the exercise. The stabilizer pad can be part of a user support structure having a seat surface, a pelvic stabilizer pad and a footrest. The footrest is positioned so the user can apply a force using the leg muscles to push the pelvis into the pelvic stabilization pad. The spatial arrangement of the stabilization assembly which comprises: pelvic stabilizer pad, seat, and footrest combination effectively immobilize the user's pelvic area, preventing it from rotating in either the anterior or posterior direction.

Abstract: An exercise apparatus that includes a frame, a rest member on the frame for receiving a user's feet, and a first and a second arm that are pivotably interconnected to each other such that the arms are pivotably movable between a start or rest position and an extended position. The first arm is coupled to the frame. A seat is provided for supporting the user and carried by the second arm. An inclined base support member is disposed under the second arm and is for supporting the second arm during the movement between start and extended positions. A carriage may be associated with the inclined base support member.

Abstract: A shoulder press exercise apparatus is provided. The shoulder press apparatus includes a selectable weight mechanism and a support member which pivotably supports a pair of four-bar linkage mechanisms. The four-bar linkage mechanisms are pivotably mounted at their rearward ends about axes which are disposed at an angle relative to a horizontal plane, i.e. are tilted relative to vertical, such that a pair of elongated bars of the four-bar linkage mechanisms travel in planes which are tilted relative to vertical. The tilted planes through which the four-bar linkage mechanisms travel enable the handles to travel along a slightly curvilinear downwardly diverging path which simulates as natural a human musculoskeletal upward pushing motion as possible.
