Two-Arm Dumbbell Preacher Curl

A strict biceps isolation exercise using a preacher bench that prevents momentum for intense muscle engagement.

Instructions

1. Grab a dumbbell in each hand and position yourself at a preacher bench or incline bench.
2. Place your upper arms on top of the preacher bench pad with the dumbbells at shoulder height.
3. Keep your elbows stationary throughout the movement.
4. As you breathe in, slowly lower the dumbbells until your upper arms are extended and your biceps are fully stretched.
5. As you exhale, use your biceps to curl the weights back up until they reach shoulder height.
6. Squeeze your biceps hard at the top of the movement for one second.

Tips

• Keep your elbows stationary on the bench throughout to isolate the biceps.
• Use a controlled tempo with emphasis on the eccentric (lowering) phase.
• Avoid swinging the dumbbells or using momentum.
• Ensure full range of motion from stretch to full contraction.
