How to do the preacher hammer curl with dumbbell
- Adjust the seat of the bench so that your arms are level with the top of the bench.
- Grasp a dumbbell in each hand with your palms facing each other, shoulder width apart and extend your arms fully along the bench.
- Keeping your arms and elbows on the bench at all times, curl the dumbbells up towards your head.
- Pause for a moment and then lower the bar back to starting position.
- Note: Perform this exercise in a slow controlled manner for best results.
Muscles worked
The prime mover is the biceps brachii, which bends the elbow and rotates the forearm palm-up.
Even with a single joint doing the moving, the muscle is not working alone — the forearms hold the grip, which is often what gives out first.
How this movement works
One joint changes angle and the resistance travels toward you along a single arc. Nothing is positioned to help, so tension stays where you aimed it and the usable load drops sharply against a multi-joint pull for the same muscle. Protect the range of motion; buying weight by shortening the arc defeats the point.
It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.
What you need
Dumbbells let each side work on its own, surfacing a strength difference between limbs that a barbell would quietly cover for, and leaving the wrist free to rotate through the movement.
