First and second pads are connected by a member which is wider at the bottom than at the top. Each pad has a ground engaging element associated therewith. A generally semi-spherical bearing is provided between each ground engaging element and its associated pad so that the pads may tilt and/or rotate relative to their ground engaging element. A removable insert is provided for limiting maneuverability and thereby facilitating ease of maintaining balance by beginners.

An amusement and/or exercising device comprising first and second pads spaced from each other, each pad being adapted to support one leg of a person, means integral with the pads and having a ribbed cross section which resists twisting and rigidly interconnecting said pads, a discrete ground engaging element below and associated with each pad, each pad having a hollow means defining at its lower end a bearing socket approximately three-quarters of a sphere, each hollow means including concentric walls extending upwardly from its associated socket with one of the concentric walls being supported by a shoulder on the outer concentric wall of its associated pad, said socket being partially defined by the lower end of said outer concentric wall, a generally spherical bearing in each socket, means releasably connecting each bearing in a rigid manner to one of said ground engaging elements, each pad being pivotable relative to its associated bearing through a limited arc to thereby facilitate tilting the pads as a unit with one pad being higher than the other and off the ground, and removable means for permitting each pad to rotate through a limited arc relative to its associated ground engaging element only in a lengthwise direction of said device.
