Setup
- Set an incline bench to a 45-degree angle.
- Lie chest-down on the bench with your feet firmly on the floor and your head clearing the top of the pad.
- Grasp the kettlebell handles with a firm pronated (overhand) grip, knuckles facing away from you.
- Let your arms hang straight down toward the floor, perpendicular to the torso.
How to do it
- Exhale as you curl the kettlebells toward your shoulders, keeping your upper arms locked in a vertical position.
- Squeeze your forearms and biceps hard at the top of the movement for a one-second pause.
- Inhale as you slowly lower the kettlebells back to the starting position using a controlled 3-second eccentric tempo.
- Fully extend your arms at the bottom without losing tension in the muscles.
Form checklist
- Keep your chest glued to the bench to prevent using momentum.
- Ensure your elbows stay pointed at the floor and do not flare outward.
- Maintain a neutral wrist position; do not let the weight of the kettlebell bend your wrists back.
- Keep your neck in a neutral position, looking slightly ahead of the bench.
Pro tips
- Focus on the 'offset' weight of the kettlebell; the center of mass is below the handle, which increases the demand on your grip and brachioradialis.
- At the top of the rep, try to pull your knuckles toward your face to maximize the contraction in the forearm extensors.
Make it harder
- Perform the movement with a 'bottoms-up' grip, holding the handle so the bell stays balanced vertically above your hand.
- Incorporate a 3-second pause at the midpoint of the eccentric phase to increase time under tension.
