The barbell close grip preacher curl is abicepsisolation exercise performed with the upper arms braced on a preacher pad and the hands inside shoulder width on a straight bar. The pad fixes the upper arms in front of the body, so the shoulders cannot swing and the biceps work hardest near the bottom, where the forearm is furthest from vertical. Bringing the hands in narrows the elbows and biases the long head, the outer part of the muscle, while the straight bar keeps the wrists fully supinated. Lifters program it as a strict second curl on arm day.
What Muscles Does the Barbell Close Grip Preacher Curl Work?
- Primary: Biceps brachii (long head, outer biceps)
- Secondary: Brachialis, brachioradialis
- Tertiary: Wrist flexors, anterior deltoid, forearm flexors (grip)
How Do You Set Up for the Barbell Close Grip Preacher Curl?
Set the preacher seat so the top of the pad sits in your armpits when you sit down. Sit with your feet flat, chest pressed to the pad and the backs of your upper arms flat against it. Take an underhand grip on the straight bar with the hands a fist's width inside shoulder width, palms up, wrists straight. Lift the bar off the rest and lower it until the elbows are almost straight.
How Do You Perform the Barbell Close Grip Preacher Curl?
- Press the upper arms into the pad with the elbows a few degrees short of locked and the wrists straight.
- Curl the bar toward your chin, driving the forearms up while the triceps stay glued to the pad.
- Stop when the forearms pass vertical and the bar is a hand's width from the shoulders.
- Squeeze the biceps for one second at the top without lifting the elbows off the pad.
- Lower the bar on a slow count until the elbows are almost straight and the biceps are fully stretched.
- Pause for a beat at the bottom, reset the grip and curl the next rep without bouncing.
What Are the Key Form Cues?
- Triceps welded to the pad: if the backs of the arms lift, the shoulder is doing the curl; push them down through the whole rep.
- Elbows in, knuckles up: the close grip wants to flare the elbows; keep them tracking straight ahead with the wrists flat.
- Slow the last quarter of the descent, where the biceps is longest and weakest.
- Keep the chest pressed to the pad so the torso cannot lean back to help.
- Think of curling the bar to your chin, not to your chest, to finish the contraction.
What Are the Most Common Mistakes?
- Loading the bar heavier than the bottom position can hold: the hips lift off the seat and the shoulders heave the bar past the sticking point; use a weight you can lower under control to a near-straight elbow.
- Dropping into the bottom: the elbow slams into extension under load with the biceps tendon stretched, the one position where this lift hurts; lower slowly and stop just short of straight.
- Letting the elbows drift off the pad at the top: the front delt finishes the rep and the biceps unload; keep the upper arms pressed down.
- Curling with the wrists: the bar rolls into the palms and the wrist flexors take over; keep the knuckles pointing up.
- Cutting the rep off halfway: the stretched bottom half is the point of a preacher; lower until the elbows are almost straight.
What Are the Best Barbell Close Grip Preacher Curl Variations?
- Barbell preacher curl: shoulder-width hands spread the work across both heads and allow more load.
- EZ bar close grip preacher curl: the angled grips ease the wrists at the cost of some supination.
- Single arm dumbbell preacher curl: one arm at a time, with the free hand steadying the elbow.
- Dual cable preacher curl: low pulleys keep tension at the bottom where a bar goes slack.
- Reverse grip preacher curl: a pronated grip moves the load to the brachioradialis.
How Do You Progress the Barbell Close Grip Preacher Curl?
- Add 5 pounds to the bar once every set reaches the top of the rep range with the upper arms flat on the pad.
- Build from 8 reps a set to 12 before each weight jump.
- Add a fourth set when three no longer leave the biceps fatigued.
- Lower on a four-count, or add a two-second pause just short of the bottom.
How Should You Program the Barbell Close Grip Preacher Curl?
Place the barbell close grip preacher curl after a standing or seated curl in an arm or pull session, once or twice a week. Work 3 sets of 8 to 12 reps with 60 to 90 seconds of rest. It pairs with a hammer curl, which covers the brachialis and forearm the supinated grip leaves out. Keep the last set strict rather than adding weight you cannot lower.
