Senso pad o with a diameter of 34 cm serves to strengthen the lumbar spine, improve balance and support concentration. It is used as a seating mat or as an unstable surface for balance exercises. When using a chair, sit on the mat in the front part so that the pelvis is tilted forward. To begin with, we recommend a shorter sitting time, which you gradually increase. The pad is inflatable, with the help of a needle valve it is possible to regulate the amount of air in the pad. The more you inflate the pad, the harder the exercise, because balance is more difficult. The upper side is equipped with barbs.
