Setup
- Set an incline bench to a 45-degree angle.
- Lie face-down (prone) on the bench with your upper chest resting against the top edge and your feet firmly on the floor for stability.
- Grip the barbell with an underhand (supinated) grip at shoulder-width.
- Let your arms hang straight down toward the floor, perpendicular to the ground, with your elbows fully extended.
How to do it
- Exhale and curl the bar toward your forehead by flexing only at the elbows, keeping your upper arms locked in a vertical position.
- Squeeze your biceps forcefully at the top of the movement for a one-second peak contraction.
- Inhale and slowly lower the barbell back to the starting position using a controlled 3-second tempo.
- Stop just short of a full lockout at the bottom to maintain constant tension on the biceps.
Form checklist
- Keep your chest glued to the bench to prevent using momentum or 'cheating' the weight up.
- Ensure your elbows remain pointed directly at the floor and do not swing forward or backward.
- Maintain a neutral neck position by looking slightly ahead of the bench rather than straight down.
- Keep your wrists stiff and neutral to avoid excessive forearm involvement.
Pro tips
- Focus on driving your pinky fingers toward your shoulders at the top of the movement to maximize bicep peak activation.
- Imagine your upper arms are pinned to an invisible wall; only your forearms should move throughout the entire set.
Make it harder
- Add a 3-second isometric hold at the top of every rep to increase time under tension.
- Perform '1.5 reps' by doing a full curl, lowering halfway, curling back to the top, and then lowering all the way down.
