Balance cushion for individual fitness training. With the balance pad, you can train your balance, coordination, and fitness. This relieves and stabilizes your spine while automatically strengthening your back and abdominal muscles when sitting on the cushion. When used while standing, the air cushion strengthens joints and trains balance. When lying down, specific exercises are intensified by the wobble cushion. Regardless of the starting position, the instability caused by the air filling leads to activation of the core muscles. This is automatically trained and strengthened. With the included hand pump, you can determine the instability of the cushion yourself. The double-sided nub surface simultaneously promotes circulation and provides a pleasant massage effect.
