Abstract
Disclosed is an exercise machine providing an upper body exerciser portion adapted for use with a lower body exerciser and having a semi-dependent retraction system. The exercise machine generally includes a frame adapted to be mounted on a lower body exerciser (though standalone versions are also disclosed) and the upper body exerciser consisting of first and second user members for pulling by a user to provide pull forces, single retraction means for providing retraction forces to the user members sufficient to retract them back to their start positions after being pulled out, and, non-floating combining means coupled to the single retraction means for making the retraction forces semi-dependent on the pull forces, and thereby reducing travel of the retraction means, by coupling the single retraction means to both user members. Drive and resistance means are further provided.

10. A method of operating a treading exerciser assembly having a treadmill including a movable surface, and further having an upper body exerciser coupled to the treadmill, the upper body exerciser including a torsion spring having a first end, a second end, and an intermediate spring portion connected between the first end and the second end, a first user member adapted to be engaged by a user'"'"'s hand and movable from a first retracted position toward a first extended position, a second user member adapted to be engaged by a user'"'"'s other hand and movable from a second retracted position toward a second extended position, and a connecting assembly including a shaft supported for pivoting movement and coupled to the first end of the torsion spring, a first pulley supported for pivoting movement with the shaft, the first user member being coupled to the first pulley, and a second pulley supported for pivoting movement relative to the shaft and coupled to the second end of the torsion spring the second user member being coupled to the second pulley, the method comprising:
-
moving the movable surface; energizing the intermediate spring portion of the torsion spring to create stored energy in the intermediate spring portion of the torsion spring by moving the first user member toward the first extended position, movement of the first user member toward the first extended position causing pivoting movement of the first pulley and the shaft to thereby energize the intermediate spring portion of the torsion spring; moving the first user member and the second user member in substantially opposing directions at substantially the same time and rate, movement of the first user member causing pivoting movement of the first pulley and the shaft and movement of the second user member causing pivoting movement of the second pulley relative to the shaft; and maintaining the stored energy in the intermediate spring portion of the torsion spring substantially constant while the first user member and the second user member are being moved in substantially opposing directions at substantially the same time and rate. - View Dependent Claims (11, 12, 13)
