ABSTRACT:
A lightweight and portable exercise device has a base frame that folds quickly and easily between a highly compact stored configuration and a deployed configuration ready for use. The exercise device include a compact support platform connected by pivot links to the base frame, and a pivoting lift bar is coupled to the base frame and will bear against the support platform to permit lifting of the support platform as the pivot links pivot with a variably selected mechanical moment arm. In use, a person stands on the support platform and lifts his or her own weight by pulling upwardly on an outer end of the lift bar. The lift force required for a given weight on the support platform is controlled by the selected lift bar moment arm. Lift straps connected to the lift bar include easily grasped handles that are adjustable in length to accommodate persons of different size and further to permit the device to be used for different exercise routines.
