Setup
- Set an incline bench to approximately 45 degrees.
- Lie chest-down on the bench with your feet secured on the floor and your head clearing the top edge.
- Hold a dumbbell in each hand with a supinated (palms forward) grip, letting your arms hang straight down toward the floor.
How to do it
- Exhale and curl the dumbbells toward your shoulders by flexing at the elbows while keeping your upper arms perfectly vertical.
- Squeeze your biceps forcefully at the top of the movement for a one-second pause.
- Inhale and slowly lower the dumbbells back to the starting position over a 3-second count.
- Fully extend your arms at the bottom to ensure a full range of motion before starting the next rep.
Form checklist
- Keep your upper arms perpendicular to the floor at all times.
- Ensure your chest remains in contact with the bench to prevent swinging.
- Avoid tucking your chin into your chest; keep a neutral spine.
- Keep your wrists straight and firm throughout the movement.
Pro tips
- Rotate your pinkies toward your shoulders at the top of the curl to maximize the peak contraction of the biceps.
- Focus on the mind-muscle connection by imagining you are pulling the weight through your pinky finger rather than your thumb.
Make it harder
- Incorporate a 3-second pause at the midpoint of the eccentric phase to increase time under tension.
- Perform the exercise unilaterally (one arm at a time) to increase the stability demand on your core.
