An air-filled and durable Crylon ball. The material is odorless, latex-free, very durable up to 500 kg (guaranteed space safety in case of damage to the outer skin up to 90 kg) and made from 100% recyclable plastic.

What does he do?
Strengthen abdominal, back and full body muscles through safe, effective and dynamic back and stability training. It can train the muscles of the back sitting in an upright position and in motion.

How does it work?
While sitting on the ball, an upright posture is automatically adopted to prevent falling off the ball. At the same time, the muscles of the pelvis, abdomen and back are involuntarily used again and again to balance the ball while sitting. The product packaging includes instructions with specific exercise suggestions.

In case of damage from objects such as sharp edges, needles, broken glass, scissors, etc., the ball skin material prevents the ball from suddenly opening. Air escapes only slowly through the hole. Explosion is impossible and injury due to unexpected fall is avoided.
