Therefore, in the state where the user is seated, the exercise assisting device can tilt the seating surface in all directions while keeping the bottom surface grounded by moving the waist with the grounded foot as a base point. Moreover, since the said exercise assistance tool has the seat surface height of the said specific range, it can ensure the movement range of the seat surface accompanying the inclination of the said seat surface large in a moderate range. That is, the movable range of the user's waist can be widened. Therefore, the user can effectively twist the muscles of the lumbar region by, for example, increasing the radius of rotation in the rotational motion of the lumbar region by using the exercise assisting tool.

Therefore, the exercise assisting tool 1 can substantially eliminate the sinking of the bottom surface 3 due to the weight of the user by using a relatively hard material for the bottom surface member 13. As a result, the exercise assisting tool 1 can easily maintain the shape of the bottom surface 3. Further, by using a relatively soft material for the seat member 12, the exercise assisting tool 1 can reduce the burden on the user's waist and improve the fit. Moreover, the exercise assistance tool 1 can also make the seat surface member 12 function as a control means for suppressing the shift of the user's buttocks. In addition, the same effects as those of the first embodiment can be obtained.
