A volleyball strength trainer mounted on a volleyball frame comprises tension ropes, a suspension arm, a handle, a tension rope fixing part and a suspension arm fixing frame. One end of each tension rope is fixed to the lower portion of a vertical column of the volleyball frame through the tension rope fixing part, and the other end of each tension rope is fixed onto a pulley at the top of the suspension arm. The suspension arm is fixed by the suspension arm fixing frame which is capable of adjusting height of the suspension arm, a pulley is arranged on the lower portion of the suspension arm fixing frame, and the suspension arm fixing frame is fixed onto the upper portion of the vertical column of the volleyball frame through a bolt and a safety pin. The direction of the suspension arm is opposite to that of a volleyball net, and the suspension arm has two functions including adjusting the height of the pulley, at the handle, of the tension rope and bypassing a weight box of the volleyball frame for facilitating training. By the aid of the volleyball strength trainer, training on strength and skilled movement of in-situ serving, jump serving and jump smashing of volleyball can be realized. Since the two tension ropes different in strength are mounted on the trainer, different strengths can be selected according to training requirements.
