Strength training system with folding frame

Abstract

In one example, a strength training system includes a folding frame having a central sub-frame and first and second lateral sub-frames, and pivoting cross members pivotally coupling the central sub-frame to at least one of the first and second lateral sub-frames, the folding frame being configured to move between an unfolded position and a folded position in which the first and second lateral sub-frames are generally parallel in the unfolded position. The strength training system also includes a strength training assembly coupled to the folding frame. The strength training system may include a pulley machine that includes pulleys and cables. In at least one example, the pulleys and cables may be secured to the folding frame in a pre-assembled manner. Further, in at least one example, the strength training system may be assembled without the use of tools.
