Weight training structures

Abstract

A weight training structure includes two exterior structures, a strut connected between the two exterior structures, two interior structures, and a lifting structure movably connected to the two interior structures and configured to support weight. Each exterior structure has a plurality of walls defining an internal portion. Each interior structure is positioned in the internal portion of and movably connected to one of the exterior structures. The lifting structure is movable between a raised position in which the lifting structure is not in contact with the two interior structures and a lowered position in which the lifting structure is in contact with the two interior structures forcing the two interior structures to move between an extended position and a retracted position in the internal portion of the two exterior structures. Other example embodiments of weight training structures, exterior structures, interior structures, lifting structures, etc. are also disclosed.
