ABSTRACT:
An exercise apparatus for providing improved muscle conditioning via push-ups or similar exercises. The apparatus comprises an elongated body with end supports and two rotatably affixed hand grips. The elongated body has a plurality of pairs of bushing lined holes. Each hole of each pair is equally spaced from the elongated body's vertical centerline. The hand grips are rectangularly shaped having a pin extension that slidably and rotatably fits in the body's bushing lined holes. The top horizontal portion of the rectangle is an ergonomically shaped handle. The pin and, consequently, the hand grip are locked into place in the body via a spring clip which engages the pin at its free end. The spring clip engages the underside of the body such that the hand grips cannot be withdrawn from the body until the clip is removed. While being used, the user grabs the ergonomically contoured handles and performs a push-up or similar exercise. The invention allows the user to properly space the hand grips for maximum comfort and variation of exercises. While pushing up and returning down, the user can rotate his hands and wrists through a mechanically limited range of motion as demanded by the body's natural tendency to do so during such an exercise.
