Overview

About PRx Small Soft-Sided Plyo Box

The PRx Small Soft-Sided Plyo Box offers a safe, space-saving way to train explosive power. Made with the same shin-saving foam as the standard size, it’s perfect for smaller spaces while still supporting box jumps, step-ups, and other plyometric movements.

Adjustable Jump Heights

With three different side lengths — 16", 18", and 24" — you can tailor the challenge to your skill level. This makes it a great tool for gradual progression or accommodating multiple users.

  • Three height options in one box
  • Durable, non-slip vinyl cover
  • Foam interior for safe landings
  • Compact design for easy storage
  • Kid- and beginner-friendly

Durable and Safe Design

The non-slip vinyl surface keeps you steady during jumps, while the foam construction reduces the risk of injury from missed landings. It’s lightweight, portable, and perfect for home gyms.

  • Shin-saving foam core
  • Easy to move and store
  • Supports a variety of exercises
  • Ideal for limited-space gyms
  • Long-lasting performance
