ABSTRACT:
An exercising, e.g., waterless swim training apparatus is disclosed having a frame and a support for the trainee's torso where the torso support is movable along a curve that is convex to the ground below, thus simulating the rocking, or rolling motion experienced in swimming. The frame and body support provide an obstruction free region so that the user can practice breast stroke, butterfly, back stroke and free style strokes without touching any part of the frame, ground, etc. with his/her fingers. The obstruction free zone is roughly a circular hemi-cylinder, extending below the trainee's body. A resistance mechanism is provided to resist motion of the user's hands. The resistance mechanism presents a force versus velocity relationship that simulates the force versus velocity relationship experienced during swimming. One embodiment uses a hydraulic pump in connection with variable valves and a fluid reservoir.
