ABSTRACT:
This device consists primarily of a pair of parallel spaced-apart sides, which are arcuately curved on the bottom, so as to be in rocking-like engagement with a ground, or floor, surface. The device includes, in the upper portion, between the sides, a rotatable member, upon which a person stands and holds onto, for effecting a somersault motion, and the device further includes a transverse member on each end of the sides, so as to enable the person using it, to somersault safely.
