Setup
- Stand behind a preacher bench adjusted so the top of the pad sits firmly in your armpit.
- Hold a dumbbell in one hand with a supinated (palms up) grip.
- Extend your arm fully across the pad, ensuring the back of your upper arm and triceps are flush against the cushion.
- Adopt a staggered stance with your feet for maximum stability and balance.
How to do it
- Exhale and curl the dumbbell toward your shoulder by contracting the biceps, keeping your upper arm glued to the pad.
- Squeeze the bicep hard at the top of the movement, stopping just before the forearm is vertical to maintain tension.
- Inhale as you slowly lower the dumbbell back to the starting position using a controlled 2-3 second tempo.
- Complete the full set on one arm before switching to the other side.
Form checklist
- Keep your armpit tucked tightly against the top of the pad.
- Avoid leaning back or using your torso to swing the weight up.
- Maintain a neutral wrist; do not let it collapse backward or curl excessively.
- Stop the descent just before full elbow lockout to keep constant tension on the muscle.
Pro tips
- Rotate your pinky finger toward your shoulder at the top of the rep to maximize bicep supination and peak contraction.
- Use your non-working hand to grip the side of the bench for extra stability and leverage.
Make it harder
- Slow down the eccentric phase to 4-5 seconds to increase time under tension.
- Incorporate 'iso-holds' by pausing for 2 seconds at the midpoint of the repetition.
