Movement overview

The Double Dumbbell Preacher Curl is an isolation exercise targeting the biceps brachii. It is performed using a preacher bench and two dumbbells, allowing for controlled movement and effective muscle engagement. This exercise emphasizes the peak contraction of the biceps and helps in developing the lower part of the muscle.

Step-by-step cues

1. Sit on a preacher bench with your chest pressed against the pad and your arms extended over it.
2. Hold a dumbbell in each hand with an underhand grip, palms facing up.
3. Start with your arms fully extended but not locked out.
4. Curl the dumbbells upward by bending your elbows, keeping your upper arms stationary against the pad.
5. Continue lifting until your biceps are fully contracted and the dumbbells are at shoulder level.
6. Pause briefly at the top of the movement for maximum contraction.
7. Slowly lower the dumbbells back to the starting position, maintaining control throughout.
8. Repeat for the desired number of repetitions.

Technical tips

• Ensure your elbows remain fixed on the pad to isolate the biceps effectively.
• Focus on a slow and controlled movement to maximize muscle tension.
• Avoid swinging or using momentum to lift the weights.
• Keep a slight bend in your elbows at the bottom to maintain tension on the biceps.
• Exhale as you lift the weights and inhale as you lower them.
• Adjust the seat height so that your armpits are comfortably resting at the top of the pad.
