6-in-1 Soft Foam Plyo Box / Squat Box

Two interlocking soft foam plyo boxes that give you six different plyo heights — where versatility and happy shins live in perfect harmony.


In Stock





Save your shins and maximize your floor space with 6 different
plyo heights in one foam box!

Say NO to bloody shins and wasted floor space, and say YES to your new favorite plyo box.

Our three-sided dense and durable foam plyo box comes with a built-in compartment for a smaller, three-sided thick foam squat box. The tough, synthetic leather covering keeps the box in prime shape and ready for years of faithful service.

Each foam plyo box is shaped like a rectangle, so it gives you three different heights in one space-saving setup.

Benefits of the 6-in-1 Soft Foam Plyo Box

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.

  • Develops fast-twitch fibers: The goal of plyometrics is to maximize muscle contraction, quickly, which essentially means that a byproduct of plyometric training is that you will develop power. Plyometric training can strengthen fast-twitch fibers and increase the ratio of fast-twitch fibers to slow-twitch in your body.
  • Increases the strength of tendons: Which means fewer injuries. Plyometrics strengthens the tendons and improves their elasticity by placing stress on them in a controlled setting. Numerous studies support the use of plyometric to reduce ACL injury risk.

Bells of Steel 6-in-1 Soft Foam Plyo Box /  Squat Box Review

Bells of Steel

The foam plyo is great for so many exercises; the possibilities are endless. Enjoy the gains, Erica and the B.o.S crew!

Charles E.

Solid and heavy!

The box is very well made, heavier than I expected but in a good way; gives it stability. The inner box is not the easiest to extract because the tight fit makes it a bit of a vacuum; a way to alleviate that would make it much easier to use. Happy with the purchase

Great box!

It’s a good purchase. Real good purchase. A little Upset with how it come out of the packing box. The insert was twisted and the box was a little deformed. It works great so no complaints.
