An extremity supporting exercise system is described. The system includes two knee sliders and two hand sliders. Each knee slider includes a knee pad and a knee base. The knee pad includes a recessed portion that is adapted to receive a user's knee. A patella support is disposed within the knee portion to support the user's patella when using the knee slider. Alternatively, each hand slider includes a hand pad and a hand base. The hand pad includes a series of finger indentations that are flanked by thumb receptacles. Importantly, the knee base and hand base are formed of a rigid and slippery material to allow the sliders to easily slide across a ground surface. Thus, through use of the exercise system, a user can support their hands and knees while sliding the hands and knees across a ground surface to perform a variety of exercises.
