Bosu is a spherical half ball on one side and flat on its base. It was invented in 1999 and is an essential part of the routine of footballers.
It tones the muscle, sculpts the body, burns fat, corrects posture and alignment of the back. The staff of Atlético de Madrid and Real Madrid usually use it regularly in their training. It is also used in patients who, after an injury or operation, have already recovered and rehabilitated with Pilates.
