Abstract: A new and useful portable adjustable multi-purpose exercise device which is collapsible when not in use, relatively inexpensive, allows for a multitude of exercises to be performed for every major part of the body and focuses on exercises which implement the user's body weight as resistance. The device essentially comprises two triangular support frames and an attached stabilizer bar, which when assembled yields a pyramidal prismatic structure upon which the user performs a variety of exercises. The configuration of the device changes as the user optionally places an exercise grip bar in various receiving grooves. This device is believed to be useful in the home setting, whereby the individual user may obtain a full work-out without the need for larger home gym systems. A device according to the invention is also believed to be favorable for use in large gym environments, hospital therapy rooms, classes and other fitness-related facilities.
