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. Lying down, specific exercises are intensified by the wobble cushion. Regardless of the starting position, the instability from the air filling always activates the inner muscles, which are thus automatically trained and strengthened. With the included hand pump, you can determine the level of instability of the cushion yourself. The dual-sided nubby surface simultaneously promotes circulation and provides a pleasant massage effect.
