The Togu Sitting Ball ABS is an air-filled and burst-proof therapy and training ball featuring an ABS Anti-Burst System. The Crylon material is odorless and highly durable (up to 500 kg, with guaranteed burst safety for damage to the outer skin up to 120 kg). The product is latex-free and contains no prohibited plasticizers. The sitting ball primarily strengthens your abdominal, back, and core muscles through safe, effective, and dynamic back and stability training. Additionally, sitting upright and moving on the ball can help prevent or alleviate back problems. Furthermore, it promotes improved coordination and better balance. While sitting on the ball, an upright posture is automatically adopted. At the same time, the pelvic floor, abdominal, and back muscles are involuntarily engaged to balance the body. In the event of damage from objects such as sharp edges, needles, glass shards, or scissors, the material of the ball's surface prevents sudden tearing. Air escapes only slowly through the hole. A sudden burst is impossible, and injuries from an unexpected fall are avoided.
