Hammer Strength Plyo Boxes are rugged and durable enough to handle any athlete. Plyo Boxes are designed with materials, refined geometries and textures to ensure a safe and effective training session time after time


Build explosiveness and jump height by stacking plyo boxes or use separately to create a plyometric training circuit.

Made with form following function – each top facing surface is designed to help stability when jumping. The plyo box is made from a soft, ultra-dense foam center and slightly less dense outer core, reducing the hardness of edges; and it also has a 76x92cm landing area, providing space and stability for jumps.

They are covered with reinforced vinyal on all four faces, and the top has an anti-slip surface heat welded on for enhanced grip, less wrinkles and less slippage from sweat. Velcro and tabs are used to keep stacked boxes secure, but can also be easily tucked out of the way for quick customization.

Stack and securely Velcro together to provide a landing surface high enough to train max vertical jumps.


  • Thermally welded top facing anti-slip surface
  • Reinforced vinyl for less wrinkles and higher durability
  • Velcro and flaps securely lock stacked boxes together.
