The Bells of Steel six in one Plyo box has an interlocking box system that makes it easy to store and takes up minimal space in your gym. Simply use the handle on the smaller inner box to lift out the hidden squat and plyo box.

Once this inner box is removed, you can use the smaller, dense foam box for box squats as well as a smaller plyo box work. After you are finished with the smaller box, reinsert it into its hole and voilà — now you have an elite foam plyo box that won’t wreck your shins if you miss your landing.
