Conditioning

Every experienced athlete has a story about a wooden plyo box and a shin. A soft foam box removes that risk entirely, which is why foam has become standard in commercial conditioning studios and why it is the sensible choice for training alone at home.

KEY FEATURES

High-density foam core, safe on missed jumps
Three jump heights from a single box
Non-slip textured cover for secure landings
Handles for repositioning between sets
Stable base that will not tip on an off-centre landing
Suitable for box jumps, step-ups and depth drops

PRODUCT OVERVIEW

The case for foam is straightforward risk management. A missed box jump on a plywood box means a shin striking a hard edge at speed, which is one of the more unpleasant injuries in training. A foam box compresses on contact, so a missed rep is a bruise rather than a hospital visit. That difference is why foam boxes dominate commercial group training floors.

The trade-off is compression under load. Foam gives slightly on landing, which means the effective height varies a little and the surface is less rigid than plywood. For pure box jump training this is unimportant. For heavy loaded step-ups, a rigid wooden box gives a more consistent platform.

TRAINING APPLICATION

Three heights in one unit covers the full progression: a low setting for step-ups, box squats and beginners, a mid setting for standard box jumps, and a high setting for advanced plyometrics. Box jumps train rate of force development and reactive strength, while step-ups and box squats provide unilateral strength and a controlled depth reference for squatting.

HOW TO CHOOSE?

Choose the soft box if you train alone, coach beginners, or jump at heights where a miss would be costly. Choose the wooden box if you want maximum rigidity for loaded step-ups and box squats, or prefer the traditional feel. Whichever you choose, always step down from a box rather than jumping down, as repeated depth landings accumulate a lot of joint stress.

FAQs

Is a soft box less stable than a wooden one?

A well-constructed foam box has a wide stable base and will not tip. It does compress slightly on landing, which makes it marginally less rigid but far safer on a missed jump.

What are the three heights?

The box is rotated onto a different face for each height. Check the stated dimensions on the page for the exact measurements.

Can I do loaded step-ups on it?

Yes, though foam compresses under load. For heavy loaded step-ups a rigid wooden box gives a more consistent platform.

Should I jump down from the box?

No. Step down. Repeated depth landings place high stress on knees, ankles and Achilles tendons for very little training benefit.

Questions & answers

What sizes does the Soft Plyo Jump Box come in?

The Soft Plyo Jump Box comes in Small (16 x 18 x 20 inches, about 41 x 46 x 51cm), Medium (16 x 20 x 24 inches, about 41 x 51 x 61cm) and Large (20 x 24 x 30 inches, about 51 x 61 x 76cm), or as an All Box Set containing all three.

How do I get three heights from one box?

Each Soft Plyo Jump Box is a rectangular block, so you simply rotate it onto a different face. The Large box, for example, gives you a 20-inch, 24-inch or 30-inch platform depending on which side is up.

What is the Soft Plyo Jump Box made of?

The Soft Plyo Jump Box has a high-density foam core with a non-slip textured vinyl cover and handles for repositioning between sets. The wide base is designed not to tip on an off-centre landing.

Is a foam box safe if I miss a jump?

Yes. A missed jump on the Soft Plyo Jump Box means your shin meets foam that compresses on contact, rather than a hard plywood edge. That makes it well suited to training alone, coaching beginners or jumping at heights where a miss would be costly.

Can I do weighted step-ups on the Soft Plyo Jump Box?

Yes, but the Soft Plyo Jump Box gives slightly under load, so the platform is a little less rigid than plywood. For heavy loaded step-ups and box squats where a fixed height matters, our Wooden Plyo Jump Box is the better tool.

Should I jump down off the box?

Step down from the Soft Plyo Jump Box between reps rather than jumping down. Repeated depth landings load knees, ankles and Achilles tendons heavily for little benefit. Save depth drops for deliberate, programmed plyometric work.
