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.

The present invention discloses a swing exercise machine including a support frame, a pair of footrests disposed at both sides of support frame and at least one suspension arm disposed between footrests and support frame, each footrest is rotatably connected to at least one suspension arm, and a pivot assembly is provided between the support frame and each suspension arm. The present invention is equipped with a support frame, a pair of footrests, and at least one suspension arm disposed between each footrest and support frame, each footrest is rotatably connected to at least one suspension arm, the connected X and Y pivot assemblies are disposed between suspension arms and support frame to allow footrests to swing back-and-forth, left-and-right. The present invention has simple structure and small volume, can realize effect of large-scale forward, backward, left and right movement of footrests through suspension arms, thus can effectively realize fitness effects.

A step exercise apparatus with a self-centering pedal system. The system comprising a frame and a seat supported from the frame. A first pedal assembly and a second pedal assembly are pivotally supported from the frame positioned so as to be manipulable by a user seated in the seat. A linkage is positioned in communication with the first pedal assembly and the second pedal assembly such that movement of either pedal assembly in a first direction causes movement of the other pedal assembly in a second direction opposite of the first direction. A brake is preferably employed for resisting motion of the first pedal assembly and the second pedal assembly in at least the first direction. A centering system positions the first and second pedal assemblies in a substantially central position when not being manipulated by the user.

Apparatus and associated methods may relate a to natural gait upper body ergometer and gait therapy (UBEGT) device having a support frame within which is suspended rotationally coordinated left and right natural gait modules (NGMs). A position of each NGM may be defined by corresponding left and right pivot arms which are rotatably coupled to a left and right side of the support frame, respectively, and wherein each gait training module is provided with a corresponding foot support and knee support. The UBEGT may be provided with an upper body ergometer (UBE) rotatably coupled to a front of the support frame and configured to rotate a shaft rotatably connected to the left and right pivot arms when a hand crank is rotated.

Exercise machines having a user support and at least one user engagement actuator assembly wherein motion of the at least one user engagement actuator assemblies is resisted in both the push and pull directions by the resisted rotation of a one-direction flywheel that is operatively engaged with a braking mechanism. The resistance of the push direction can be less, greater, or equal to the resistance of the pull direction. Each user engagement actuator assembly can be configured to create various unique push and pull exercise stations. Multiple exercise stations can be mounted on each machine that can be operated independently or concurrently.

A sports training device includes a stand, pivot axis, elements for a person training to apply force, and load device for creating an adjustable load. The load device includes weights and a U-shaped guide acting to protect against unauthorized removal of the weights, one end of which guide is connected via a bracket to the pivot axis, which is secured to the stand. The pivot plane of the load device is directed perpendicular or parallel or at an angle to a support surface. The center of mass of the load device is shifted, in the presence of even a minimal load, left or right from the pivot axis or coincides with the pivot axis. The elements for a person training to apply force are installed, relative to the load device, at a given height from the support surface in accordance with the direction of force from the person training and in accordance with the group of muscles receiving the load.

A weight bar foot plate device for safely performing leg presses includes a plate and a set of couplers. The couplers, which are coupled to a top of the plate, are configured to couple the plate to a weight bar of a leg press machine so that a bottom of the plate is positioned below the weight bar. The bottom of the plate is configured to position feet of a user who is supinely positioned below the plate, positioning the user to perform a leg press exercise.
