Exercise equipment is disclosed which comprises a spherical sector-shaped member with an upright column erected therein, a base plate mounted on the upper end of said column, an arm with the base end rotatably carried on said column and the free end projecting outwardly from the gap between the spherical sector-shaped member and the base plate. When the user stands on the base plate bodily movement rotates the rotatable arm. The number of rotations of the rotatable arm is indicated by a display device connected to an electric detection circuit while at the same time an audible signal is sounded every time the rotatable arm makes one rotation so that the user can detect his or her progress related to the dynamic equilibrium while practicing a willful exercise with pleasure.
