The exercise equipment includes a chair frame having a first side frame, a second side frame and a "C" shaped rear frame. The "C" shaped rear frame fits inside and is secured to the top of the first and second side frames for holding the entire chair frame in place. A seat with a back support includes four support straps with four suspension rings attached to the ends of the straps. The four suspension rings are attached to one end of four coil springs. An opposite end of the coil springs is attached to the chair frame. Two of the coil springs are secured to the rear frame and the other two coil springs are secured to the front of the first and second side frame. The four support straps are adjustable for people of different heights and weights. Also the back support may include a safety belt to prevent the user of the chair from slipping off or bouncing off the seat. The seat also includes four seat rings attached to the underside of the seat at its corners. Each of the seat rings is used for receiving the hook ends of bungee cords or other securing types of material. The bungee cords are wrapped around a portion of the front and back of the first and second side frames. The bungee cords steady the seat from moving when a user, for example a wheelchair person, is transferred from the wheelchair onto the seat and prior to the exercise program.
