DETAILED DESCRIPTION I claim: 1.
A jump and twist exercising apparatus for controlled enforcement of natural body movements, and including; a supporting base with a first vertically disposed turning axis and a forward extension with a second vertically disposed turning axis spaced from and parallel to said first axis, a platform rotatably carried by bearing means on the first mentioned turning axis and having opposite side portions with standing room defined by a barrier member of vertical height therebetween and extending diametrically through the turning axis, a body support comprised of a handlebar with a stem rotatably carried by bearing means on the second mentioned turning axis and having opposite side hand grips at a height to be grasped for body support and control, and drive means for inversely turning the platform and barrier with respect to manipulative turning of the handlebar by a person jumping the barrier from one side portion of the platform to the other.
2.
The jump and twist exercising apparatus as set forth in claim 1, wherein the bearing means rotatably carrying the platform on the first mentioned turning axis is an anti friction means comprised of ball bearings operating in opposed races in the base and at the periphery of the platform.
3.
The jump and twist exercising apparatus as set forth in claim 1, wherein the barrier has a normal passive position extending fore and aft in alignment from the first mentioned to the second mentioned turning axes.
4.
The jump and twist exercising apparatus as set forth in claim 1, wherein the barrier member height is determined by replacement with a barrier member of selected height.
5.
The jump and twist exercising apparatus as set forth in claim 4, wherein said barrier member replacement is by means of an upwardly opening socket in the platform receiving an anchor depending from a barrier member of selected height.
6.
The jump and twist exercising apparatus as set forth in claim 1, wherein the barrier member is a planar fence of flexible material adapted to be stepped upon without injury
