Setup
- Set an incline bench to an angle of approximately 45 degrees.
- Lie prone (chest-down) on the bench with your feet firmly on the floor or the bench supports for stability.
- Grasp a pair of dumbbells with a firm pronated (overhand) grip, palms facing your legs.
- Let your arms hang straight down toward the floor, ensuring your shoulders are retracted and stable.
How to do it
- While keeping your upper arms stationary and perpendicular to the floor, exhale as you curl the weights toward your shoulders.
- Squeeze your forearms and biceps hard at the top of the movement for a one-second pause.
- Inhale as you slowly lower the dumbbells back to the starting position using a controlled 3-second eccentric tempo.
- Stop just short of full elbow lockout at the bottom to maintain constant tension on the target muscles.
Form checklist
- Keep your elbows fixed in space; do not allow them to swing forward or flare outward.
- Maintain a neutral wrist position throughout the movement to avoid excessive strain on the wrist joint.
- Ensure your chest remains glued to the bench to prevent using momentum from the lower back.
- Keep your neck in a neutral position, looking slightly ahead of the bench.
Pro tips
- Squeeze the dumbbell handles as hard as possible to increase neural drive and maximize forearm recruitment.
- Focus on the 'mind-muscle connection' by imagining you are trying to touch the back of your hands to your anterior deltoids.
Make it harder
- Add a 2-second isometric hold at the peak of the contraction on every rep.
- Perform the eccentric (lowering) phase even slower, taking 5 seconds to reach the bottom.
