The CAP 3-in-1 Plyometric Jump Box is a single, rotating platform that delivers three training heights (20, 18 and 16 inches) with a non-slip textured surface for confident jumps and versatile lower-body workouts.
This durable plyo box is built for progressive plyometrics, step-ups, lateral drills and HIIT circuits where compact storage and quick changes matter. The 20 x 18 x 16 in model fits a wide range of skill levels, offering a stable interlocking construction, countersunk hardware and integrated handles so it performs reliably in home, garage or studio environments.
Rotating the box provides three distinct heights without needing extra equipment, so you can move quickly between exercises or advance jump height as you get stronger. That flexibility reduces clutter and allows graduated progressions for safe skill development.
The textured top improves traction and makes foot placement more predictable during explosive movements and quick footwork. It’s designed to give users extra grip without needing additional tape or mats.
Interlocking panels and countersunk screws form a firm platform that resists wobble through repeated use. Smooth-finished edges and recessed hardware minimize catch points, while the engineered wood base meets CARB compliance for indoor use.
Integrated wide carry handles make repositioning the box fast and safe, so you can rearrange circuits or stow the box between sessions. Its compact shape fits most home gym spaces and is light enough for one person to handle comfortably.
Who is this for? The CAP 3-in-1 Plyometric Jump Box (20 x 18 x 16 in, Non-Slip) is intended for athletes, fitness enthusiasts and home-gym users who want a single, space-saving platform for plyometrics, step-ups, conditioning and agility training. It suits beginners progressing to intermediate jumpers as well as coaches needing a reliable, portable box for classes or small studios.
Q: Can one person move the CAP 3-in-1 Plyometric Box?
A: Yes. Wide integrated handles let one person comfortably lift and reposition the box for workouts or storage.
Q: What heights are available on the 20 x 18 x 16 inch model?
A: Rotate the box to use 20, 18, or 16 inch heights, offering progressive options for jumps and step-ups.
