Step-by-step instructions
Follow these cues to master proper technique and stay safe through every rep.
- Step 1Setup
- Sit on a preacher bench with your feet flat on the ground.
- Adjust the seat height so that your upper arms rest comfortably on the bench pad.
- Step 2Grab the Dumbbells
- Pick up a dumbbell in each hand using a neutral grip (palms facing each other).
- Ensure your grip is firm but not overly tight to avoid unnecessary tension in your forearms.

- Keep your wrists straight and aligned with your forearms.
- Step 4Curl the Dumbbells
- Engage your biceps and curl the dumbbells upwards towards your shoulders.
- Keep your upper arms stationary on the bench and avoid using momentum.
- Step 5Lower the Dumbbells
- Slowly lower the dumbbells back to the starting position, fully extending your arms.
- Maintain control throughout the movement to maximize muscle engagement.
- Step 6Repeat
- Perform the desired number of repetitions while maintaining proper form.
- Focus on a smooth and controlled motion with each curl.
- Step 7Finish the Exercise
- After completing your reps, carefully place the dumbbells down on the floor or a rack.
- Stand up from the preacher bench while keeping your back straight.
