Preacher Curl

The preacher curl is a must-have exercise in weight training for sculpting massive, powerful biceps. Performed on an incline bench, it perfectly isolates the bicep and enables deep muscle work. If you want to improve your technique, discover the muscles involved, and avoid injuries, this article is for you.

Exercise Technique

The preacher curl is performed on an incline bench, often called a Larry Scott bench. It can be done with an EZ-bar like a classic barbell curl, with dumbbells like a concentration curl, or with a cable machine.

Steps to perform the preacher curl correctly:

1. Adjust the bench to the right height: your armpits should rest on the pad.
2. Grip the bar or dumbbells with a supinated grip (palms facing up).
3. Keep your elbows fixed on the pad throughout the entire movement.
4. Contract your biceps and slowly raise the weight to shoulder height.
5. Lower the weight in a controlled manner, without fully extending your arms.

Muscles Targeted

The preacher curl primarily targets the biceps brachii, but it also engages secondary muscles to stabilise the movement.

Focus on the muscles worked:

• Biceps brachii: this is the main muscle worked, and thanks to the isolation provided by the pad, it is engaged to its maximum.
• Brachialis: a deep muscle located beneath the bicep, it adds volume and a rounded appearance to the upper arm.
• Brachioradialis: a forearm muscle that assists in elbow flexion.

You can also vary your training with an incline dumbbell curl or a spider curl to target the same muscle groups.

What Are the Benefits of the Preacher Curl?

The preacher curl offers numerous benefits for beginners and experienced athletes alike.

The main benefits:

• Maximum isolation: thanks to the pad, there is no way to cheat. Only the biceps work.
• Full control of the movement, promoting both muscle contraction and stretch.
• Less stress on the lower back, unlike standing curls where compensatory movements can appear.
• Targeted development of the lower portion of the bicep to achieve that sought-after peak.

Mistakes to Avoid to Stay Injury-Free

Like any weight training exercise, the preacher curl requires flawless execution to prevent injuries.

The most common mistakes:

• Lifting too heavy: always prioritise a weight that allows clean execution.
• Lifting your armpits off the pad: this reduces isolation and can incorrectly load the shoulders.
• Lowering the weight too quickly: the eccentric phase is just as important as the concentric lift.
• Rounding the back: always maintain a straight, stable posture.
• Fully extending the arms at the bottom of the movement, which can put the elbow joint at risk.

Coach’s Conclusion

The preacher curl is a king exercise for anyone who wants strong, well-defined biceps. It delivers perfect isolation and constant tension – both essential for making progress in weight training. By working slowly, without cheating, and maintaining proper posture, you will see fast and lasting results.

Incorporate this exercise into your biceps routine, vary the weights and angles, and above all, stay consistent. The key is regularity and discipline.
