A swim trainer comprising: a base; an upright member extending from the base; two arms each carried by the upright member and terminating with an end pulley; two pull cords each having one end connected to a hand pull, extending from the hand pull over the end pulley, a second pulley positioned adjacent to the upright member, and then along the upright member; a rotatable shaft positioned adjacent to the base; a loading mechanism, connected to the shaft, to resist rotation and unwinding of the cord around the shaft; a clutch assembly positioned on the shaft arranged to rotate the shaft when the handle is pulled down and otherwise spin freely; a rewind bias means to rewind the cord around the shaft; and, a tipping and/or rotating balance platform assembly, seated on the base, for the swimmer to stand on, when pulling the hand pull.

1. A vertical swim trainer comprising: a base;an upright member attached to and extending upwardly from the base;two arms each carried by a top portion of the upright member and terminating with an end pulley positioned above a front portion of a swimmer's shoulder when the swimmer is standing on the base;two pull cords each having one end connected to a hand pull, having a central portion extending from the hand pull over the end pulley, then over a second pulley positioned adjacent to the arm and the upright member, and then down along the upright member;a rotatable shaft positioned adjacent to a lower portion of the upright member and the base, having its axis generally perpendicular to the unwound pull cord to accommodate the pull cords being wound therearound;a loading mechanism, connected to the shaft, to resist rotation and unwinding of the cord around the shaft when the hand pull is pulled down;a clutch assembly positioned on the shaft arranged to rotate the shaft when the hand pull is pulled down and to spin freely when the hand pull is returned to its upper initial position;a rewind bias means to rewind the cord around the shaft, and concurrently pull the hand pull up and back to the initial position after it has been pulled down to a lower position and released; and,a tipping and/or rotating balance platform assembly, seated on the base, for the swimmer to stand on, when pulling the hand pull;thereby requiring the swimmer to utilize the core muscles in the body when pulling on the handle to maintain body alignment and rigidity, thus better developing both arm and torso strength required for fast and efficient swimming. 2. A vertical swim trainer as in claim 1, wherein the balance platform assembly tips and comprises a tipping control means to vary and control the amount of tipping. 3. A vertical swim trainer as in claim 2, wherein the tipping control means comprises an inflated wheel tube, positioned on a rotating disc, said wheel tube pressurized to regulate tipping. 4. A vertical swim trainer as in claim 1, wherein the balance platform assembly is rotatable and comprises a rotation control means which provides variable bias to limit and control the amount of rotation. 5. A vertical swim trainer as in claim 4, wherein the rotation control means controllably biases the rotating platform to a central forward position so that a swimmer standing thereon would tend to generally face forward. 6. A vertical swim trainer as in claim 5, wherein rotation control means comprises a square plate, rotatably attached to a rotating bearing assembly, and an elasticized cord having first ends tied to adjacent rear corner portions of a square plate, and second ends releasably held by eccentric clamps, attached to a rear portion of the base, so that the tension of the elasticized cords may be set thereby determining the amount of central forward bias of the balance platform. 7. A vertical swim trainer as in claim 4, wherein the balance platform assembly both tips and rotates, and wherein the balance platform assembly further comprises a removable hand screw, extending through a rotatable square plate and then into the base, to maintain the square plate in a non-rotatable central forward position, so that a swimmer standing thereon would consistently face forward, to thereby allow an inexperienced swimmer to successfully balance on a tipping platform before additionally having to cope with rotation of the balance platform. 8. A vertical swim trainer as in claim 1, wherein the loading mechanism is an eddy current resistance comprising a magnet wheel variably spaced from an eddy current disc, one of which rotates, and one of which is stationary; so that induced eddy currents in the eddy current disc which oppose angular rotation, can be selectively varied by varying the spacing between the magnet wheel and the eddy current disc. 9. A vertical swim trainer as in claim 1, wherein the clutch assembly comprises a one way clutch insert which is positioned within a cord winding sleeve, all of which are pressed on the shaft, so that the sleeve can rotate in two directions, only one of which rotates the shaft. 10. A vertical swim trainer as in claim 9, wherein the rewind bias means comprises an elasticized cord which is wound on the cord winding sleeve when the handle is pulled down, which rewinds the sleeve, rewinding the pull cord on the sleeve, and upwardly biases the handle pull, when the handle pull is not held in the lower position. 11. A vertical swim trainer as in claim 4, wherein the hand pull comprises a horizontal planar portion held on opposite sides by an inverted yolk which is centrally attached to the pull cord, thereby enabling a swimmer to visually ensure that the palm of his hand when seated and pulling on the planar portion is correctly aligned, perpendicular to the pull cord.
