<p>An exercise machine devised to exercise the muscles associated with two adjacent joints, for example the shoulder and elbow or the hip and knee, comprises a support frame 10 and a first gear wheel 14 mounted for rotation about a first pivot 15 fixed relative to the frame. An elongated link 17 is pivoted at one end upon the first pivot and carries a second gear wheel 19 upon a second pivot 18 at its other end. The gear wheels are linked together by drive means, for example a chain 20, and a lever 21 is provided to rotate the second gear wheel. A resistance means 24 applies a load opposing rotation of the first gear wheel. When a user adopts a position in which his relevant joints correspond approximately to the positions of the respective gear wheels and then applies a pressure upon the lever, both of his joints are exercised. Preferably gears 14, 19, link 17, chain 20 and lever 21 are duplicated to allow both sides of the body to be exercised together. <IMAGE></p> |
