A waist twisting apparatus may include a base, a supporting portion, and a seat. A platform is formed at a top portion of the base, and a central portion of the platform has a first axle hole. The supporting portion vertically formed on the base comprises a main body, and a first edge and a second edge thereof are respectively formed at an inner edge and an outer edge of the main body. The main body is further connected to a first axle rod and a second axle rod respectively, and the first axle rod comprises a first connecting portion while the second axle rod has a second connecting portion. The wheel is pivotally installed at a bottom portion of the main body. The seat has a bottom shell, and a second axle hole is formed at a center bottom portion of the bottom shell.

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.

An apparatus adapted to function as an exercise belt having two (2) adjustable ends formed as hooks and operable to be secured about sides of a chair or a seat in a motor vehicle. The adjustable ends further include a threaded means to allow both adjustable ends or either adjustable end to be threaded in or out to achieve a desired length. The desired length is selectively adjustable so that a user may isometrically push against the exercise belt while seated and have the exercise belt provide resistance to exertion provided by the user.

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.

An auxiliary device for muscle strength training is provided, which includes: a base; a sliding member slidingly coupled to the base; and a connecting-rod mechanism connected to the base and the sliding member in such a way that a positional shift of the sliding member allows the connecting-rod mechanism to rotate relative to the base and change its state. As such, the auxiliary device has first and second configurations to assist patients who are incapable of controlling their muscles by themselves to effectively train specific muscle groups. Further, elastic members are connected to the base and the connecting-rod mechanism and provide elastic potential energies so as to keep the auxiliary device in static equilibrium. The auxiliary device has a simple structure and is easily manufactured at a low cost and applicable for patients with muscle strength lower than grade 3.

The invention comprises an exercise device for back and abdominal muscles to be fastened onto a wheelchair.

Handles for use in exercise apparatus and in lifting apparatus are provided.

An exercise system includes a base module having a seat portion having a seat depth in a lengthwise direction from a front portion of the base module toward a rear portion of the base module, and an adjustable back module configured to fixedly engage with the base module at a first seat depth and a second seat depth different from the first seat depth in the lengthwise direction.

A seat-based exercise station providing a body with a planar operative surface for supporting a plurality of leg engagers and a plurality of band connectors disposed there along, wherein the leg engagers are located to engage the legs of a chair that is supported by the body. The band connectors allow a user seated on the seat to utilize elastic bands, by way of the band connectors, for performing a multitude of cardiovascular exercises while so seated.
