The GYMBALL was specifically developed for use in functional training. Whether you're doing coordination and stability training or working out with additional weights, the BLACKROLL®GYMBALL is the perfect training partner.
It is odor-neutral, latex-free, elastic, can handle loads up to 500 kg, and is also outstanding for everyday sitting for proper back posture. It can be used for training while standing, sitting, lying on your stomach, or on your back. That means a wide variety of muscle groups can be addressed with different intensity.
The GYMBALL is training equipment and a sitting ball at the same time. While seated on the ball, you are automatically forced to assume proper posture just to keep your balance. The pelvic, abdominal, and back musculature is therefore continually used and exercised. The anti-burst system (ABS®) prevents the ball from bursting in case of external damage Air escapes only slowly at the point of damage, allowing the exercise to be ended safely.
