Handles for use in exercise apparatus and in lifting apparatus are provided. The handles have an elongated handle body with a top head, a bottom head, and a central bore extending along a longitudinal axis. A top pulley is coupled to the top head and is rotatable around a top axis that is substantially perpendicular to the longitudinal axis. A bottom pulley is coupled to the bottom head and is rotatable around a bottom axis that is substantially perpendicular to the longitudinal axis. At least one secondary pulley is associated with at least one of the top pulley and the bottom pulley. A cord is disposed on a circumferential surface of the top pulley, the cord passing through the central bore and being disposed on a circumferential surface of the bottom pulley, so that when the handle body is moved, the top and bottom pulleys rotate to allow the cord to travel smoothly through the central bore.

1. An exercise handle comprising: an elongated handle body having a top head, a bottom head, and a central bore extending along a longitudinal axis;a top pulley coupled to the top head, the top pulley being rotatable around a top axis that is substantially perpendicular to the longitudinal axis;a bottom pulley coupled to the bottom head, the bottom pulley being rotatable around a bottom axis that is substantially perpendicular to the longitudinal axis;at least one secondary pulley associated with at least one of the top pulley and the bottom pulley;a cord disposed on a circumferential surface of the top pulley, the cord passing through the central bore and being disposed on a circumferential surface of the bottom pulley, such that when the handle body is moved, the top and bottom pulleys rotate to allow the cord to move through the central bore. 2. The handle of claim 1, wherein at least one of the top and bottom pulleys comprises a circumferential groove or depression that receives the cord. 3. The handle of claim 1, wherein the cord is anchored at each of two ends. 4. The handle of claim 1, wherein at least one of the top and bottom heads is rotably coupled to the handle body around the longitudinal axis. 5. The handle of claim 1, wherein the top head and the bottom head are fixed to one another and rotably coupled to the handle body around the longitudinal axis. 6. The handle of claim 1, wherein the top head and the bottom head are independently rotably coupled to the handle body around the longitudinal axis. 7. The handle of claim 1, wherein the top and bottom heads are fixed relative to the handle body. 8. The handle of claim 1, wherein the handle body has a hollow cylindrical shape. 9. The handle of claim 1, wherein the cord is elastic. 10. The handle of claim 1, wherein the cord is non-elastic. 11. The handle of claim 1, wherein the cord has a circular cross-section. 12. The handle of claim 1, wherein the cord has a non-circular cross-section. 13. The handle of claim 1, further comprising a locking mechanism that locks a position of the cord. 14. The handle of claim 13, wherein the locking mechanism comprises a ratchet. 15. The handle of claim 1, further comprising a grip that at least partially covers the handle body. 16. The handle of claim 1, further comprising a strap configured to strap the handle to a user's limb or other appendage. 17. The handle of claim 1, wherein the cord has a first end and a second end, the first and second ends of the cord being anchored to one or more fixed objects or loads, the cord being disposed on a circumferential surface of the top pulley so that the cord enters a central bore through a top opening of the handle, the cord extending through the central bore of the handle and exiting the central bore through a bottom opening of the handle, the cord being then received on a circumferential surface of the bottom pulley, such that when the handle is moved, the top and bottom pulleys rotate to allow the cord to translate through the central bore. 18. The handle of claim 17, wherein the first and second ends of the cord are anchored at the same location on a fixed object or load. 19. The handle of claim 17, wherein the first and second ends of the cord are anchored at different locations on one or more fixed objects or loads. 20. The handle of claim 17, further comprising one or more anchors configured to anchor at least one end of the cord to a fixed object or load.
