An apparatus for use during the performance of squat-jump type exercises utilizes a weight-laden frame which is grasped by the hands of a user during the performance of the exercise routine and leg members associated with the frame which are spring-biased from a retracted position toward an extended position. During an exercise routine performed with the apparatus, the apparatus is lifted from the floor during a jump phase of the routine and is returned to the floor during a rebound phase of the routine. The spring-biased leg members of the apparatus cushion the effects of the weight-laden frame as the apparatus is returned into contact with the floor and facilitate the lifting of the apparatus during a subsequent jump phase of the routine.

An apparatus for use during the performance of a squat-jump type of exercise routine wherein the exercise routine includes a jump phase during which the user lifts the apparatus from the floor and a rebound phase during which the user returns the apparatus to the floor, the apparatus comprising: a frame within which a user stands for the performance of a squat-jump type of exercise routine and including hand grips with which the apparatus is lifted from the floor by the user during the jump phase of the exercise routine and is returned to the floor during the rebound phase of the exercise routine wherein the hand grips are connected to the frame and disposed on opposite sides of the user as the user stands within the frame wherein the frame includes a front, a rear, and a beam which extends between the front and the rear of the frame on each side of the user; leg members for engaging the floor and through which the weight of the frame is transferred to the floor when the apparatus is rested thereon, the leg members being connected to the frame so that each leg member is movable relative to the frame between an extended condition and a retracted condition; and means associated with the frame for biasing the leg members from the retracted condition toward the extended condition so that when the apparatus is in a spaced relationship above the floor, the leg members are maintained in the extended condition by the biasing means and so that when the apparatus is lowered to the floor during the rebound phase of the exercise routine, the leg members engage the floor and are permitted to move relative to the frame toward the retracted position under the weight of the frame and in opposition to the force of the biasing means to thereby cushion the impact of the apparatus against the floor.
