Abstract: A balance pad includes a base. A plurality of first pillars and a peripheral wall are uprightly disposed on the base. The peripheral wall surrounds the first pillars so that the first pillars are located within the peripheral wall. Thereby, the first pillars reduce the stability of the balance pad to increase the difficulty of doing balance exercise. The peripheral wall surrounds the first pillars, so that the first pillars can abut against the peripheral wall to avoid excessive inclination of the first pillars to cause injury to a user.
