Apparatus for use during the performance of squat-jump type exercises
摘要:
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.
