An exercise device having one or two wood plaques with relatively flat, inverted U-shaped members extending vertically upright thereon. The U-shaped members are tubular and include horizontal portions with ends thereon extending downwardly into the plaques which serve as bases. Internal members in the ends include projections extending through the bases and engaged by locking members countersunk into the bases. The locking members are covered by non-skid mats. Collars encircle the aforementioned ends to aid in holding the U-shaped members upright.
