What Are Barbell Bicep Curls?

The barbell bicep curl is a fundamental arm exercise that targets the biceps brachii using an overhand grip. It's particularly effective for building overall arm mass and grip strength.

Proper Barbell Curl Form in 5 Steps

1. Stand upright with feet shoulder-width apart
2. Grip barbell underhand (palms up) at hip-width
3. Keep elbows pinned to sides throughout movement
4. Curl bar to shoulder level without swinging
5. Lower slowly (3-4 seconds) to full arm extension

Pro Tip: Squeeze biceps at top position for 1 second to maximize muscle activation.

Key Benefits
