Claim:
An exercise device comprising: a gripping member configured to be suitable for gripping with both hands by a user, the gripping member being further configured with at least two end portions, the end portions joined with an adjustment member that enables a length of the gripping member to be adjusted within a predetermined range; an adjustment member cover covering the adjustment member that provides safety to the user; and two wheels disposed about and rotatably joined to the end portions of the gripping member, each of the wheels comprising a width greater than a diameter of the wheels and a plurality of circumferential grooves for rolling on a vertical surface where horizontal stability is improved at least by the horizontal constraining tendency of normal and frictional forces generated as the wheels engage the vertical surface, the wheels further being configured to engage a vertical motion guide wherein each of the wheels is joined to a one of the end portions in a manner such that sides of each of the wheels are substantially unobstructed for engagement to the vertical motion guide, thereby assisting the user to balance against the vertical motion guide while performing a squat exercise within a space provided by the vertical motion guide.
