Q: What is the EZ-Bar Preacher Bench Curl?

The EZ-Bar Preacher Bench Curl is a isolation (single-joint) resistance exercise targeting the Biceps Brachii (Short Head / Thickness) and Biceps. The cambered EZ-bar takes wrist strain off the ulnar nerve while the 45-degree preacher pad produces strict biomechanical isolation on the biceps short head.

The cambered EZ-bar takes wrist strain off the ulnar nerve while the 45-degree preacher pad produces strict biomechanical isolation on the biceps short head.

list_alt STEP-BY-STEP BIOMECHANICAL EXECUTION

Seat Setup & Armpit Lock

Sit into bench, tuck armpits into pad top, grasp inner curved knurling of the EZ-bar.

                    VECTOR CUE: Wedge armpits over pad • Grip inner curves • Triceps flush against pad
                  

Full Curl Arc

Curl bar up until forearms are near vertical, contracting biceps maximally.

                    VECTOR CUE: Curl upward • Squeeze inner biceps head • Keep wrists rigid
                  

Peak Contraction Hold

Hold the peak squeeze for 1 second at the top.

                    VECTOR CUE: 1-second peak squeeze • Keep torso anchored
                  

Slow Extension

Lower the bar in 3 seconds down the pad slope, stopping just short of full elbow lockout.

                    VECTOR CUE: 3-second descent • Soft elbow stop • Don't slam bar into rest

Synergists: Brachialis, Forearms

Recommended Tempo: 3-1-1-0

Rest Period: 90 Seconds

warning COMMON MISTAKES & PRECISION FIXES

MISTAKE: Violently dropping the bar into full elbow lockout at the bottom

FIX: Decelerate the bar over 3 seconds and stop with a slight micro-bend at the bottom to protect distal bicep tendons.
