In accordance with this invention, a device is provided which is able to develop upper body strength, including doing exercising such as pull-ups, push-ups, tricep presses, tricep presses, dips, arm curls, flys, etc. Also with the device of the invention abdominal and leg muscles could be developed by such exercises as sit-ups, leg-lifts, leg extentions and back rests. The exercise device preferably comprises a horizontal bar adapted for being selectively gripped by the hands of a user or supporting the user's legs. A means is included for adjusting the length of the bar. At least two sets of vertical support structures support the bar at at least two based locations. Each of the vertical supports structures includes means for adjusting the length of its structure whereby the elevation of said bar may be varied in accordance with a particular exercise program. The device may be used for performing an exercise program by adjusting the horizontal bar to the desired length and adjusting the vertical support structures to the desired height. The horizontal bar is gripped by the user's hands. The user the moves his body towards the horizontal bar under the force from the user's and holds the body in place for a predetermined time. The body is then moved toward original position and the various steps are repeated until the exercise program is complete. A similar exercise program may be performed by using additional parts with the device such as elastic bands or a slant board.
An exercise device comprising two sets of spaced vertical support structures defining an open space therebetween, a horizontal bar adapted for being selectively gripped by the hands of a user or for supporting the user's legs, said horizontal bar being mounted to and spanning said support structures to maintain said support structures spaced from each other, said horizontal bar comprising a plurality of bars slidably mounted against each other to comprise a sliding horizontal bar unit which is adjustable in length for controlling the extent of said space between said support structures, each of said support structures comprising two sets of tubes slidably mounted against each other to adjust the overall height of each of said sets of tubes, each said sets of tubes comprising an upper tube and a lower tube, wherein the space between said supports is unconstrained, a movable lockable stabilizing structure connected to a respective tube of each of said sets of tubes to selectively maintain said sets of tubes in a fixed relation to each other, said stabilizing structure being connected to said upper tubes whereby said stabilizing structure may remain locked when said height of said sets of tubes is adjusted, each of said sets of tubes having an upper end and a lower end, said lower end being adapted to rest on the ground, and said upper end of each of said sets of tubes being pivotally mounted to said horizontal bar to permit said sets of tubes in each of said support structures to be pivoted toward each other in a side by side relationship with all of said tubes being aligned after said stabilizing structure has been unlocked and moved to from a compact unit for storage and transportation when said sets of tubes have been adjusted to their fully contracted shortest height and said sliding horizontal bar unit has been fully contracted to its shortest length and said device has an attachment means which would be allow other exercising attachments to be attached to said device for engaging of exercises.
