4FIZJO Slam Ball 10 kg medicine ball, 23.5 cm
The 4FIZJO Slam Ball is a 10 kg medicine ball for strength training, circuit training and CrossFit. This version measures 23.5 cm in diameter and features an Anti-Bounce system to prevent rebound after impact with the ground.
Grip and impact absorption
- Surface: reinforced, abrasion-resistant PVC with a non-slip pattern and raised rings helps maintain a grip, including with wet hands.
- Filling: sand and iron filings leave some internal space unfilled, allowing the ball to flatten on landing and absorb impact.
- Valve: allows internal pressure adjustment; the safety valve protects against bursting caused by impact-related pressure increases.
Exercise options
Use the ball for warm-ups, strength work, isometric exercises and balance exercises. It can also serve as an added weight for squats, forward and reverse lunges, abdominal crunches, torso rotations and ball raises while standing or lying down.

Does the Slam Ball rebound after impact?
The Anti-Bounce system prevents rebound. The ball is not completely filled, so it flattens on landing to absorb impact.
