Illustrated guide to the Curl Bar Curl exercise

Curl Bar Curl

EZ-bar biceps curl — the curl variation that's friendlier to most lifters' wrists than a straight bar while loading the biceps similarly hard.

Level: Foundation

Primary: Biceps

Movement: Isolation

Tags: Pull

Type: Strength (Weight Lifting)

Equipment: Barbell

Sports: Baseball Wrestling

Target muscles

The biceps brachii is the prime mover through elbow flexion. The brachialis underneath contributes meaningfully. The brachioradialis assists, with slightly more involvement than a strict-supinated curl because the EZ-bar's angled grip puts the forearm in a position between supination and neutral. The forearms hold the bar isometrically. The trunk and shoulders stabilize. The EZ-bar's slight grip rotation reduces the strain on the wrists that a straight bar can create at heavier loads — for most lifters, this is the better curl bar.

How to perform

Setup

Grip the EZ-bar at the angled portion where your wrists feel naturally aligned — for most lifters, that's the inner angled section, palms slightly turned in. Stand tall with feet hip-width apart, slight knee bend, elbows pinned to the sides. Trunk braced.

Execution

Curl the bar up by flexing at the elbows — the upper arms stay stationary at the sides. Stop short of locking the bar against the shoulders; pause briefly at the peak contraction (about chin height). Lower the bar over a count of two to three to the fully extended position. The wrists stay in their natural alignment with the bar throughout; don't cock them back to assist or curl them in to chase peak contraction.

Common mistakes

  • Swinging the torso to launch the bar. The body stays still.
  • Letting the elbows drift forward to shorten the lever. Pin them to your sides.
  • Going too heavy. The biceps cap the working weight; ego loading kills form.
  • Cocking the wrists back to "include" the forearms. Wrists stay in line with the bar.
  • Bouncing the bar at the bottom. Stop short of locking out and reverse — or come to full extension and pause, but don't bounce.

Progressions and regressions

Regress to dumbbell curls if the EZ-bar bothers your wrists, or use lighter loads until the pattern is clean. To progress, work pause curls (3-second pause at peak contraction), 21s (seven half-reps bottom, seven half-reps top, seven full), or cheat curls on the last 1-2 reps of a strict set.

Programming notes

Accessory work after the main pulling. 3-4 sets of 8-12 reps. Two or three times a week. Pair with hammer curls for full elbow-flexor development. Don't program right before a session that needs heavy grip strength — fried biceps bleed into pull-ups and deadlifts the next day.
