ABSTRACT:
A portable exercise device includes a base having a flat central section on which the user may either stand, sit or lie and a strap housing on each side of the central section. The base comprises two sections joined by mating extrusions such that the base may be disassembled to provide greater portability of the exercise device. One of the strap housings contains a supply/takeup reel onto which left and right straps are wound and from which they are unwound during a workout by the user. The right strap is routed underneath the base and around an idler pulley contained within the other housing. Each of the straps exits its respective housing and is connected to one end of an exercise bar. A rewind spring, a one-way clutch, and a band brake are coupled to the supply/takeup reel to adjust the force required of the user to pull the straps during a workout and to rewind the straps when the user releases the bar.
