A waist fitness apparatus includes main body and a resilient cover. The main body has a base pivotally connected with a supporting board through an eccentric unit, and the base is used to distribute the weight of the user, so the main body can be stably disposed on the ground. The present invention is advantageous because the height of the supporting board is higher than the height of the knee height of an average adult, the user does not have to bend the knees when sitting on it to increase the comfortableness. Also, the supporting board can be dragged back to its original position by the cover when it is not in use, so the user does not have to adjust the supporting board.

The present application relates to a physical therapy device to strengthen and prevent atrophy in muscles for use while seated in a chair or a wheelchair or while lying in a bed. The physical therapy device includes a back rest; right and left upper arm rests coupled to the back rest by a first connector; and right and left lower arm rests coupled to the right and left upper arm rests, respectively, by a second connector. Each lower arm rest comprises a handle. Each upper arm rest is configured to move towards the back rest at the first connector to fold flush against the back rest. The physical therapy device further comprises an extender coupled to the back rest; right and left upper leg units coupled to the extender by a third connector; and right and left lower leg units coupled to the right and left upper leg units, respectively, by a fourth connector. Each lower leg unit comprises a stirrup.

The invention provides an apparatus, system and method for reducing the size of portable rotary motion exercise devices. Flexible materials in contact with the user or a piece of furniture is part of the connection between the user and the exercise device. Multiple wraps of a band around a shaft provide adjustable rotational resistance.

A weight training machine for allowing at least two of a user's muscle groups to push or pull simultaneously in a synchronized and unified fashion, having at least one common counter or weight resistance mechanism; a first actuating means operatively connected to the at least one common counter or weight resistance mechanism for allowing actuation of the at least one common counter or weight resistance mechanism by a first of the user's muscle groups, and a second actuating means operatively connected to the at least one common counter or weight resistance mechanism for allowing actuation of the at least one common counter or weight resistance mechanism by a second of the user's muscle groups, wherein actuation of both the first actuating means and the second actuation means simultaneously acts upon and or resists against the at least one common counter or weight resistance mechanism. One embodiment is an exercise machine and a drive or actuating mechanism with a lever and fulcrum configuration. The fulcrum has an attached handle, arm, lever or platform means, bearings for operatively cooperating with an axle and/or the lever, and attachment means for additional actuating member or members being operatively connected to the axle. The lever has a means for contact with the user and a weight means for providing a counterweight to the weight of the user, as well as attachment means for operatively connecting with the fulcrum and/or axle. The actuating member or members are attached to the fulcrum, preferably pivotally, and comprise linkages to the axle and/or lever so as to be able to transfer force from the user to the lever. Other embodiments include weight training machines having a moment arm weight, weight stack, or weight plate weight resistance mechanism for creating a weight resistance or weight load.

An exercise chair includes a frame and a seat rotatably coupled to the frame. First and second front support members are coupled to the frame in laterally spaced part relation and first and second rear support members are coupled to the frame in laterally spaced part relation, the first and second front support members and the first and second rear support members cooperating to support the frame above a surface.

A treadmill arrangement, having a treadmill stand and an endless belt which runs over rollers mounted in the treadmill stand and is driven by a drive, with one surface of the endless belt serving as a walking or running surface. A motion state detection device is allocated to the treadmill to detect a motion state or a positional change of the legs and/or feet of the user relative to the treadmill stand and to obtain a control signal for the drive.

The present disclosure provides a movable ball chair, including an elastic ball and a support frame, wherein the support frame includes a plurality of connecting tubes bent downward and a plurality of supporting tubes bent upward, the supporting tubes and adjacent connecting tubes are connected end to end to form a three-dimensional closed loop in a manner that the included angles between planes of the supporting tubes and the planes of the adjacent connecting tubes are the same, the bottom of each supporting tube is provided with a connecting hole, the central axis L of the connecting hole is inclined from top to bottom toward the direction where the central axis L0 of the elastic ball in the vertical direction is located, the included angle between the central axis L of the connecting hole and the straight line Y is a, the value range of a is 0.25-5, a sleeve assembly is welded to the interior of the connecting hole, the outside diameter of the sleeve assembly is matched with the inside diameter of the connecting hole, the sleeve assembly is provided with a through hole, the sleeve assembly is connected to a moving piece through the through hole, and the through hole, the sleeve assembly and the connecting hole are arranged coaxially. Free movement of the ball chair is achieved by the movable ball chair described in the present disclosure, and the movable ball chair has the advantages of simple and stable structure.

Exercise devices can provide multidirectional and dynamic resistance to movement of a user, such that complex movements can be evaluated and assessed. An exercise apparatus includes a shaft, a user engagement structure coupled to the shaft, a position sensor coupled to the shaft configured to detect a position of the shaft, and a processor operatively coupled to the position sensor. The processor is configured to receive position data from the position sensor, calculate position coordinates based on the position data that are representative of a position of the user engagement structure, determine whether the position coordinates are within a previously-defined region, and count a repetition when the position coordinates are within the previously-defined region.
