4FIZJO Slam Ball 7 kg medicine ball, 22.5 cm
-1%
The 4FIZJO Slam Ball is a 7 kg medicine ball for strength training, circuit training and CrossFit. It measures 22.5 cm in diameter and uses an Anti-Bounce system to prevent rebound after impact with the floor.
Grip and construction
The shell is made from reinforced, abrasion-resistant PVC. Its non-slip surface and raised rings help maintain a grip even with wet hands. The filling consists of sand and iron filings.
- No rebound: the ball is not completely filled, allowing it to flatten on landing and absorb its momentum.
- Safety valve: protects against bursting caused by increased internal pressure from impacts.
- Adjustable pressure: the valve allows the pressure inside the ball to be adjusted.
Training options
Use the ball for warm-ups, strength exercises, isometric exercises and balance work. It also serves as an added weight for squats, forward and reverse lunges, abdominal crunches, torso twists and ball raises while standing or lying down.
