An exercise device that exercises both flexor and extensor muscles. The exercise device includes a base. First and second sidewalls upwardly extend from opposing sides of the base. Each of the first and second sidewall has a plurality of teeth formed on an upper rim extending from the front end to the rear end of the base. At least a first gear is secured to a first end of an elongated rod and at least a second gear is secured to a second end of the elongated rod. A plurality of teeth of the first gear interlock with the plurality of teeth of the first sidewall and a plurality of teeth of the second gear interlock with the plurality of teeth of the second sidewall. A board rests on the elongated rod in between the first end and the second end.

An elliptical stepper includes a base, a damping device mounted on the base, two crank devices respectively laterally mounted to two opposite sides of the damping device. Each crank device has a stepping device mounted thereon and each stepping device has a roller set mounted to a bottom thereof, wherein the roller set is universally rolled relative to a corresponding one of the two stepping device. The base includes two opposite sides each having a guiding structure disposed thereon. Each guiding structure includes at least one rail having a front end outwardly extending relative to a center line of the base. Each roller set is moved along a corresponding one of the two guiding structures such that each stepping device provides a wiggling effect when moved along an elliptical route.

A treadmill is provided according to various embodiments herein. The treadmill includes a frame; a front shaft coupled to the frame; a rear shaft coupled to the frame; and a running belt disposed about the front and rear shafts, wherein the running belt assumes at least a portion of a curved running surface, the curved running surface having a radius of curvature of approximately 88 to 138 inches.

There is proposed an apparatus for joint exercise and rehabilitation. The apparatus including a housing which supports a plurality of spaced apart motion devices that enable a user to position a limb thereon or onto a platform supported thereon, such that the limb is movable along a generally arcuate path to undertake a joint exercise and/or rehabilitation activity of the limb or joint.

A treadmill is provided according to various embodiments. The treadmill includes a first rotatable element coupled to the frame; a second rotatable element coupled to the frame; an intermediate member coupled to the frame that is disposed intermediate the first rotatable element and the second rotatable element and coupled to at least one of the first rotatable element and the second rotatable element; a running belt disposed about the first and second rotatable elements, the running belt defining a non-planar surface; and a safety device coupled to the intermediate member. The safety device is operable to substantially prevent rotation of at least one of the first rotatable element and the second rotatable element in a first rotational direction and permit rotation of the at least one of the first rotatable element and the second rotatable element in a second rotational direction opposite the first rotational direction.

A treadmill is provided according to various embodiments herein. The treadmill includes a first rotatable element coupled to the frame; a second rotatable element coupled to the frame; an intermediate member coupled to the frame that is disposed intermediate the first rotatable element and the second rotatable element and coupled to at least one of the first rotatable element or the second rotatable element; a running belt disposed about the first and second rotatable elements, the running belt defining a non-planar surface; and a safety device coupled to the intermediate member. The safety device is operable to substantially prevent rotation of at least one of the first rotatable element or the second rotatable element in a first rotational direction and permit rotation of the at least one of the first rotatable element or the second rotatable element in a second rotational direction opposite the first rotational direction.

A treadmill includes a frame having a front end and a rear end, substantially opposite the front end; a front shaft assembly coupled to the frame proximate the front end of the frame; a rear shaft assembly coupled to the frame proximate the rear end of the frame; a running belt disposed about the front and rear shaft assemblies; and a bumper coupled to the frame proximate the running belt such that the bumper is disposed between the running belt and the frame. In use, the bumper is configured to selectively restrict movement of the running belt towards at least a portion of the frame.

A modular floor exercise assembly for performing floor exercises includes a plurality of floor supports that is each removably attachable together to form a bridge-like structure that can be positioned on a support surface. A pair of cross members is each removably attachable between a respective pair of the floor supports. A handle unit is removably attachable to the cross members when the cross members are attached to the floor supports. Thus, the handle unit can be gripped by a user thereby facilitating the user to perform floor exercises such as a pushup. The handle unit is slidable along each of the cross members to facilitate the user to perform the floor exercises at a variety of different angles with respect to the support surface.

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 machine for exercising arms and shoulders and reducing abdominal fat. The machine includes a frame of curve shape. Straps extend from the ends of the frame for tightening the machine over the abdomen. The frame includes an upper rail, a middle rail, and a lower rail, the upper rail and middle rail form an upper track and the middle rail and lower rail form a lower track. An upper set of rollers are mounted in the upper track and an upper handle is coupled to the upper set of rollers. A lower set of rollers are mounted to the lower track and a lower handle is coupled to the lower set of rollers. The upper handle and the lower handle are grasped to pull and push the upper set of rollers and the lower set of rollers to roll back-and-forth in the upper track and the lower track respectively.
