Barbell biceps curl
The barbell biceps curl is a classic strength training exercise that isolates the biceps brachii to build upper arm size and strength. Using a barbell allows for heavier loading than dumbbells, making it highly effective for progressive overload.

- Stand upright with your feet shoulder-width apart, holding a barbell with an underhand grip (palms facing forward) at hip level.
- Pull your shoulders back, engage your core, and tuck your elbows close to your torso.
- Exhale and curl the bar upward toward your shoulders by flexing your elbows, keeping your upper arms completely stationary.
- Squeeze your biceps hard at the top of the movement for a brief second.
- Inhale and slowly lower the barbell back to the starting position with control, fully extending your arms.

Form tips
- Keep your elbows pinned to your ribs throughout the lift to prevent the front deltoids from taking over the movement.
- Maintain a neutral spine and avoid leaning backward or swinging your torso to lift the weight.
- Focus on a slow, controlled eccentric phase, taking two to three seconds to lower the barbell.
Common mistakes
- Using hip momentum or swinging the body to cheat the weight upward.
- Allowing the elbows to drift forward or flare outward during the concentric phase.
- Cutting the range of motion short by not fully extending the arms at the bottom of the lift.
FAQ
How many reps and sets should I do?
For muscle growth, perform 3 to 4 sets of 8 to 12 repetitions with a weight that challenges you in the final reps. For strength, aim for 4 sets of 6 to 8 repetitions.
Is a straight barbell better than an EZ-curl bar?
A straight barbell maximizes biceps activation by forcing full wrist supination, but an EZ-curl bar is often preferred because it reduces strain on the wrists and elbows.
How do I stop my wrists from hurting during barbell curls?
Keep your wrists straight and locked in a neutral position throughout the movement; do not let them bend backward under the weight of the bar.
