Barbell Preacher Curl
BarbellStrength
The Barbell Preacher Curl is a strength exercise performed on a preacher bench, where you sit or stand and curl a barbell upward from the angled arm pad to isolate the biceps brachii. Its primary purpose is to build biceps size and strength by minimizing cheating through momentum and emphasizing the peak contraction phase. Ideal for intermediate to advanced lifters seeking targeted arm hypertrophy, it requires only a barbell and preacher bench.
How to Perform Barbell Preacher Curl
- 1To perform the barbell preacher curl safely and effectively, begin by adjusting a preacher bench so the angled pad supports your upper arms comfortably at chest height. Sit facing the bench with your chest pressed against the pad, feet flat on the floor for stability, and core engaged to maintain a neutral spine. Grip the barbell with an underhand shoulder-width hold, letting it rest in the crook of your elbows on the pad, arms fully extended but not locked, with shoulders relaxed and elbows flush against the pad.
- 2Initiate the movement by curling the barbell upward toward your chin, squeezing your biceps to lift while keeping your elbows pinned to the pad and upper arms stationary—avoid swinging or using momentum. Exhale steadily as you curl to the top, pausing briefly for a strong biceps contraction with forearms near parallel to the ground. Inhale as you slowly lower the barbell back to full extension, controlling the descent over two to three seconds to maximize tension.
- 3Key form cues include keeping wrists straight, elbows immobile, and back straight without arching. Common mistakes to avoid are lifting your elbows off the pad, which recruits shoulders; using body momentum by leaning back; or rushing the eccentric phase, leading to strain. Perform 3 to 4 sets of 8 to 12 reps, focusing on controlled reps for biceps strength.
