Abstract
An exercise machine that enables an exerciser to perform golf club swings, baseball bat swings, canoeing strokes, football kicks, tennis serves, ball throwing, weight lifting, bike exercise, and numerous other athletic motions with preselected amounts of resistance. The machine incorporates a free wheeling flywheel having variable resistance in one direction so that backswings are accomplished with no substantial resistance. The flywheel is positionable and lockable at a height selected by the user, and is further positionable and lockable at any preselected angle relative to a horizontal axis and at any preselected angle relative to an axis orthogonal to the horizontal axis. Attachments that simulate golf clubs, baseball bats and the like are secured to the axle of the flywheel and are swung or otherwise manipulated by the exerciser to increase the strength of muscles specifically used during the selected athletic motion.
