An exercise device has a base, an exercise platform (which can be split into a left and right platform) and two or more springs that connect the base and the exercise platform(s) and hold the exercise platform(s) substantially parallel to the base when the exercise device is not in use, preventing the exercise platform(s) from coming into contact with the base when the exercise device is in use and allowing the position of the exercise platform to vary relative to the base as weight is applied to the exercise platform(s) at different points apart from a center point of weight balance while straps can be used to stabilize or selectively vary the center point of weight balance.

What is claimed is: 1. An exercise device, comprising: a base, said base having an undersurface for placement on the floor and having an upper surface; a plurality of springs, each of said plurality of springs having a first end and a second end; an exercise platform, said exercise platform having a top surface for engagement by the user and having an undersurface; each of said plurality of springs being affixed at said first end to an upper surface of said base and at said second end to an undersurface surface of said exercise platform said exercise platform being substantially parallel to said base when said exercise device is not in use, said springs being a sole support for said platform; a plurality of flexible unitary straps, each of said straps having a first end and having a second end, each of said straps having said first end connected to said upper surface of base and said second end connected to said undersurface surface of exercise platform, said straps being sized and positioned so that they are in tension when there is no external load on said platform to stabilize the balance of said exercise platform; a socket mounted on said top surface of said base, a one-piece safety handle mounted in said socket, said one-piece safety handle having a top and having a cross bar formed in a T-bar shape so that the user of said exercise device can stand on said exercise platform and hold said handle for safety and support; and said plurality of springs and said straps being the sole constraints of said platform so that said springs and said straps allow the position of said exercise platform to vary relative to said base as weight is applied to said exercise platform at different points away from a center point of weight balance. 2. The exercise device of claim 1, wherein said safety handle is detachably connected to said base so that it extends above said exercise platform, said safety handle being positioned away from a top edge of the exercise platform so as to permit said exercise platform to move without contacting said handle and to provide support for a user standing on the exercise platform. 3. The exercise device of claim 1, further comprising: a left hand grip located at a left edge of said exercise platform; and a right hand grip located at a right edge of said exercise platform. 4. The exercise device of claim 1, wherein the exercise platform is comprised of a left exercise platform attached to a left one of said springs and a right exercise platform attached to a right one of said springs and the said left and right exercise platforms are capable of moving independently relative to each other, and a unitary strap having left and right ends, said left end of said unitary strap being connected to said left exercise platform and said right end of said unitary strap being connected to said right exercise platform. 5. An exercise device, comprising: A flat bottomed base having a bottom surface and a top surface; a left exercise platform, said left exercise platform having a top surface sized and configured to receive a human foot and having a bottom surface, said left exercise platform having a left hand grip located at the left edge of said left exercise platform; a right exercise platform, said right exercise platform having a top surface sized and configured to receive a human foot and having a bottom surface, said right exercise platform having a right hand grip located at the right edge of said right exercise platform; a left spring having a first end and having a second end, said left spring being affixed at said first end to said top surface of said base and at said second end to said bottom surface of said left exercise platform; a right spring having a first end and having a second end, said right spring being affixed at said first end to said top surface of said base and at said second end to said under surface of said right exercise platform, said right and left exercise platforms being only spring supported; a plurality of unitary flexible straps each having a first end and a second end, at least two of said straps having their first ends connected to said base and having their second ends connected to said left exercise platform and at least two of said straps having their said first ends connected to said base and their said second ends connected to said right exercise platform so that said straps limit motion of said exercise platform with respect to said base; a unitary connecting strap having a left end and having a right end, said left end of said connecting strap being connected to said left exercise platform and said right end of said connecting strap being connected to said right exercise platform to limit motion of said right exercise platform with respect to said left exercise platform, said springs and said straps being the only constraints on motion of said left and right exercise platforms with respect to said base; a swivel socket secured to said top surface of said base; a one-piece safety handle mounted in said swivel socket so that it extends above said left and right exercise platforms, said safety handle being positioned away from a top edge of said left and right exercise platforms and between said left and right exercise platforms; and said left and right springs being configured to prevent said left and right exercise platforms from coming into contact with each other or said base when a user is exercising with said exercise device and allow the position of each of said left and right exercise platforms to vary in position relative to said base and each other as weight is applied to said left and right exercise platforms away from the center point of weight balance.
