First Claim
1. An exercise machine for exercising one or more muscles of the body of an exerciser, comprising:
- a contact member movable in one direction through a distance defining a range of motion;
a source of force;
a mechanical connection that transmits a resistive force from the source of force along a resistive force vector in opposition to movement of the contact member through its range of motion; and
a support for the mechanical connection that changes the direction of the resistive force vector a plurality of times during movement of the contact member through its range of motion such that the exerciser experiences an oscillating force vector.

Abstract
A method for exercising one or more muscles of the body wherein one or more muscle(s) are contracted to move a limb through a range of motion in opposition to an oscillating resistive force. In accordance with the method, during a muscular contraction, the direction and/or the magnitude of the resistive force changes in an oscillatory fashion. The oscillations in the magnitude and/or the direction of the resistive force include a plurality of cycles during a single repetition of muscular contraction. The waveform and frequency of the oscillations may vary during a repetition or remain constant. Embodiments of devices providing an oscillatory resistive force are presented. The embodiments provide means for enabling an exerciser to perform resistance-type exercises in accordance with the method.

14. A pulley-based exercise machine for exercising one or more muscles of the body, comprising:
-
a contact member movable in one direction through a distance defining a range of motion; a cable attached to the contact member; a lead pulley having a rotational axis and a groove in which the cable is supported; a source of tensile force on the cable on the opposite side of the lead pulley from the contact member which operates to oppose movement of the contact member through its range of motion and manifests in a resistive force in the cable directed along a resistive force vector from the contact member to the lead pulley; and wherein the lead pulley changes the direction of the resistive force vector a plurality of times during movement of the contact member through its range of motion such that the exerciser experiences an oscillating force vector. - View Dependent Claims (15, 16, 17, 18, 19, 20)
