ABSTRACT:
The present invention relates to an aquatic exerciser or rehabilitation equipment and, particularly, to an exerciser mounted for positioning a user engaging component in a cantilevered configuration over the edge of a swimming pool or other water body. The exerciser suspends user engaging members over the water and allows the user to carry out various exercises within the pool. Typically, the exercises include body lifting exercises and in contrast to conventional body lifting exercises carried out outside the water, the force required by the user increases in proportion to the amount of his body that is above the water level. In other circumstances the difficulty may be increased by carrying out certain movements within the water at higher speeds with the water providing a drag force as an increasing function of the speed. Thus, the user can either increase or decrease the difficulty of the exercise easily.
