Description

GYM MASTER High Density Foam Plyo Jump Boxes

 unlock maximum vertical power and dynamic leg strength without the constant fear of painful, skin-tearing shin impacts. Traditional wooden or metal plyo platforms punish slight miscalculations with deep bruises and scraped bone, causing athletes to hesitate right at the moment of takeoff. Engineered with a shock-absorbing, high-density foam core wrapped in a durable PVC shell, this soft-sided box cushions missed landings while maintaining rigid structural stability under heavy loads.

Impact-Absorbing Core Overcomes Hard-Edge Landing Hesitation

Bare timber boxes create a psychological barrier during high-volume jump training, forcing you to hold back on explosive efforts. GYM MASTER removes this mental friction by surrounding a heavy-duty foam interior with a textured PVC leather cover that absorbs impact forces. The rigid 200kg-rated internal structure prevents top-surface caving or edge collapse, allowing you to commit fully to box jumps, step-ups, split squats, and depth drops with total confidence.

Explosive Performance Highlights

  • 3-in-1 Orientation (12", 16", 18"): Flip the platform onto different sides to switch training heights instantly without buying multiple bulky boxes.
  • Shin-Protecting Soft Foam Shell: Eliminate painful scrapes from missteps so you can push your vertical threshold safely.
  • 200kg Load Capacity: Execute weighted vest jumps and heavy step-ups on a firm platform built to resist compression or sagging.
  • Textured PVC Leather Surface: Keep an unyielding foot hold across wood, rubber, or concrete flooring during rapid cardio circuits.

FAQs

Q: Will the box tip over or cave in when landing near the outer edge?

A: The dense foam core holds its shape under loads up to 200kg, though the unit must always be placed flush against a solid wall to prevent movement during jumps.

Q: How do I change the landing height between exercises?

A: Simply rotate the box onto a different face to switch between 12-inch, 16-inch, and 18-inch training heights in seconds.
