Description
Overview
The SMAI Slam Ball 4kg is built for one job: being thrown down hard. Unlike a medicine ball it does not bounce, so every slam ends with the ball dead on the floor and you bend to pick it up again. That extra pick-up is the point, because it works more muscles across a full body functional session.
At 4 kg it is a step up from the Slam Ball 3kg for stronger students and club athletes, and still light enough to keep pace high in a circuit. It sits in the middle of the SMAI range of slam balls, with the Slam Ball 5kg above it.
Key benefits
- Works more muscles per rep because the no-bounce design forces a pick-up every time.
- Takes the hardest slams thanks to a construction designed for high impact use.
- Suits full body functional circuits rather than isolated lifts.
- Stays put after a slam, so it does not rebound at the thrower.
Who it's for
Secondary school PE and strength programmes, club gyms and coaches running functional circuits with senior players. Choose the 4 kg if your group already handles the 3 kg comfortably; move to a heavier slam ball or one of the medicine balls if you want a ball that bounces for partner throws.
Care, safety and set-up
Slam onto rubber gym flooring or a firm, level surface rather than polished timber courts that could mark. Store off the ground and wipe down after sweaty sessions.
Frequently asked questions
Does a slam ball bounce?
No. Slam balls are designed not to bounce, which is what separates them from a traditional medicine ball.
Can I mix weights for a class?
Yes. The SMAI range runs from the Slam Ball 2kg up to the Slam Ball 5kg, so you can set weights by strength and age group.
Is there quantity pricing for a school set?
Quantity pricing applies on many lines; add the balls you need and request a quote for a fit-out.
