Q: What is the Cable Preacher Curl?

The Cable Preacher Curl is a isolation (single-joint) resistance exercise targeting the Biceps Brachii (Short Head & Peak) and Biceps. The preacher pad locks the upper arms in forward flexion, completely preventing shoulder assistance while the low cable applies continuous tension even at lockout.

Pad Height Setup

Adjust seat so chest presses comfortably against pad with armpits wedged directly over the top slope.

                    VECTOR CUE: Armpits over pad bevel • Triceps flat against vinyl • Chest braced
                  

Cable Bar Grab

Grasp cable bar with underhand grip. Start with arms almost fully extended (soft elbow bend to protect tendons).

                    VECTOR CUE: Supinated grip • Don't hyperextend elbows at bottom
                  

Curl to Forehead

Curl bar upward along the arc toward forehead, focusing entirely on squeezing the inner biceps peak.

                    VECTOR CUE: Curl bar toward forehead • Squeeze peak hard for 1 second
                  

Controlled 3-Second Negative

Lower weight slowly over 3 seconds until arms are extended against the pad.

                    VECTOR CUE: 3s eccentric • Stop right before joint hyperextension
