An anchor block having within it one or more tunnels through which exercise cords are run and an equal number of slots connected to the tunnels, each slot extending from either the face or the backside of the block. In certain cases, some of the slots may extend from the face while others do so from the backside. In other cases, to enhance strength, all of the slots extend solely from the face or from the backside. This slotted arrangement is useful for a solid handgrip, strapped handgrip assembly, ankle exercise cuff assembly or anchoring door impingement assembly so that stoppered elastic exercise cords may be quickly and easily interchanged. The slot may be shaped in any of several ways including straight, zig-zag or curved.

The slotted exercise handgrip according to claim 1 wherein each cord connecting slot comprises medially pointed protrusion configuration;so that connecting security is enhanced.7. The slotted exercise handgrip according to claim 1 wherein each cord connecting slot comprises medially rectilinear protrusion configuration.8. The slotted exercise handgrip according to claim 1 wherein each cord connecting slot comprises medially curved configuration.9. The slotted exercise handgrip according to claim 1 wherein each cord connecting slot comprises serpentine configuration.10. The slotted exercise handgrip according to claim 1 wherein each cord connecting slot comprises T-shaped configuration.11. The slotted exercise handgrip according to claim 1 wherein the anchoring block further comprises ellipsoidal configuration;whereby operator control is enhanced.12. The slotted exercise handgrip according to claim 1 wherein the anchoring block further comprises banana shaped configuration.13. The slotted exercise handgrip according to claim 1 wherein the anchoring block further comprises finger guides.14. The slotted exercise handgrip according to claim 1 wherein both the number of cord terminal bores and the number of cord connecting slots is three.15. The slotted exercise handgrip according to claim 3 further comprising a gripping cylinder;wherein handgrip use is enhanced by reason of free rotation.16. The slotted exercise handgrip according to claim 3 wherein the attaching means comprises stitching.17. The slotted exercise handgrip according to claim 15 further comprising a gripping pad disposed longitudinally upon the cylinder.18. The slotted exercise handgrip according to claim 1 wherein at least one of the cord terminal bores are disposed in deliberate misalignment with the others.19. The slotted exercise handgrip according to claim 1 comprising two or more cord terminal bores and an equal number of cord connecting slots wherein all of the cord connecting slots are disposed upon one of:the face of the cord connecting block; andthe backside of the cord connecting block.
