1. An exercising apparatus comprising a support frame, said frame having four vertical corner members and braces therebetween to define a substantially upright rectangular enclosure; a platform mounted in said frame in the lower part thereof for movement in a vertical direction; means yieldingly resisting movement of said platform in the downward direction; first and second horizontal slot defining means secured to said frame in the upper part thereof; a pair of movable rods supported in the slots formed by said first and second slot defining means, said rods being movable so as to engage an exerciser''s shoulders when the exerciser is standing on said platform wherein the exerciser pushes against said movable rods whereby said platform is urged downward against the resistance of said yielding means.

7. An exercising apparatus comprising a vertical support frame; a platform; spring means connecting said platform to said support frame; a plurality of vertically spaced horizontally extending pairs of bars with each pair of bars being generally parallel to each other and mounted on said support frame above said platform so as to define increasing heights between said platform and each of said pairs of bars, means mounting each of said bars on said frame for movement toward and away from each other in a horizontal plane only wherein an exerciser will stand on said platform and engage one of said pairs of bars whereby pushing against said pair of bars will cause a force to be transmitted through the body to said platform to act against said spring means.
