Abstract: A weight training tool includes a pair of adjustable platforms or blocks. Each block comprises a support platform and a plurality of legs, the legs configured to allow conversion of the platform to at least two heights, and collapse of the platform to a compact structure having wheels for ease of transport. The legs fit into mating tubes on the underside of the platform. To provide a second height, the legs may be equipped with a perpendicular portion to fit into mating tubes on the underside of the support platform to support the platform at a shorter height. One of each of the pair of platforms is equipped with a projection on its underside which can be detachably associated with a projection on the underside of the other platform with a space formed therebetween for storing legs. Attachable wheels and a handle complete the transportable platform pair.
