A motorless treadmill is disclosed which exercises the upper body and lower body of a user. Displacement of an upper-body exercise mechanism such as a pair of reciprocating arm members rotates a drive roller, which is coupled to an endless belt through a transmission system. The transmission system employs a double-wound belt, which links the drive roller to the upper body exercise mechanism such that arm movements are translated into belt rotation. The double-wound belt allows for arm motion in both directions to directly drive the belt, through the use of one-way clutches orientated in opposite directions on the drive shaft. Further, the double-wound belt transmission system allows independent operation of each arm. A flywheel may be added to store energy to smooth the belt rotation.
A treadmill for exercising the upper body and lower body of a user, comprising, a substantially stationary support frame, an endless belt longitudinally supported on the support frame, a pair of displaceable arm members disposed astride the endless belt, each of the arm members being displaceable forwardly and rearwardly relative to the frame by a reciprocating arm movement of the user, a drive roller coupled to the belt, and a transmission system linking the drive roller to the displaceable arm members such that displacement of one displaceable arm member causes the drive roller to rotate the belt but does not cause an equal magnitude displacement in any other displaceable arm member.
