Abstract: An exercise machine wherein the muscles which move a part of the body such as the foot or head are exercised by restricting movement of the body part to rotation about each of at least two mutually perpendicular axes and providing independently adjustable resistance means to selectively resist rotational movement of the body part about each axis with a desired degree of resistance which does not vary with the position or speed of movement of the body part.

Abstract: A device for handgripping or squeezing, forearm twisting, wrist casting, wrist rocking and a combination of some of these. A handle mechanism is rotatably mounted on a frame. This mechanism includes a fixed handle and a movable handle, movement of the last mentioned handle being resisted by a force which may be varied. One may grasp the two handles simultaneously and exert the fingers so as to move the movable handle towards the fixed handle in opposition to the applied force. Rotation of the handle mechanism is provided with torsional resistance which may be varied. One may grasp the fixed handle with the arm in alignment with the axis of the device and rotate the handle mechanism in either direction or one may grasp the fixed handle with the arm disposed at right angles to the position previously described and rotate the handle mechanism in either direction.
