The upper portion includes a flat jumping surface to facilitate jumping or step-up type exercises, and the lower portion includes a sled rail portion to facilitate sliding across a surface, and a weight platform for the addition of plate weights. A number of attachment hooks facilitate the use of cords or handles to perform resistance exercises using the sled as an exercise platform.
