Movement overview

The Barbell Preacher Curl is an isolation exercise targeting the biceps brachii, performed using a barbell on a preacher bench. This exercise emphasizes the peak contraction of the biceps by minimizing shoulder movement and providing a stable platform for the arms.

Step-by-step cues

1. Adjust the preacher bench so that your upper arms rest comfortably on the pad and your feet are flat on the ground.
2. Sit on the bench and grip the barbell with an underhand grip, hands shoulder-width apart.
3. Extend your arms fully, allowing the barbell to hang in front of you while maintaining a slight bend in your elbows to keep tension on the biceps.
4. Curl the barbell upwards by contracting your biceps, keeping your upper arms stationary against the pad.
5. Continue curling until your forearms are vertical or slightly beyond, ensuring full contraction of the biceps.
6. Slowly lower the barbell back to the starting position, maintaining control throughout the movement.
7. Repeat for the desired number of repetitions.

Technical tips

• Focus on keeping your upper arms pressed firmly against the pad to isolate the biceps effectively.
• Avoid using momentum or swinging your body to lift the weight; maintain strict form for maximum muscle engagement.
• Control the lowering phase of the curl to maximize muscle tension and growth.
• Use a moderate weight that allows you to perform all repetitions with proper form without compromising technique.
• Ensure a full range of motion by fully extending and contracting your arms during each repetition.
• Consider using an EZ curl bar if it feels more comfortable on your wrists compared to a straight barbell.
