ABSTRACT:
An exercise device has two side bars each comprising a longitudinal segment extending between front and rear legs. The angle and length of the front and rear legs produces an incline of the longitudinal segment. The angle of incline is variable because the front and rear legs are separately adjustable in length. Slip locks selectively lock each leg at a desired length. Cross bars connected between the side bars by quick release locks. A central longitudinal bar parallel to the side bars extends between a selected two of the cross bars and is connected thereto by quick release locks.
