Setup
- Adjust the seat height so that your armpits rest comfortably against the top of the slanted pad.
- Sit down and grasp the barbell with an underhand (supinated) grip, hands spaced shoulder-width apart.
- Plant your feet firmly on the floor and rest the back of your upper arms flat against the pad.
How to do it
- Inhale as you slowly lower the barbell until your arms are nearly fully extended, feeling a deep stretch in the biceps.
- Exhale and curl the bar toward your shoulders by contracting your biceps, keeping your upper arms glued to the pad.
- Squeeze your biceps hard at the top of the movement for one second, ensuring you don't rest the bar against your face.
- Lower the weight with a controlled 2-3 second tempo back to the starting position.
Form checklist
- Keep your armpits snug against the pad throughout the set.
- Avoid swinging your torso or using momentum to lift the weight.
- Maintain a neutral wrist position to prevent strain on the forearms.
- Stop just short of full elbow lockout at the bottom to maintain tension and protect the joint.
Pro tips
- Focus on driving your triceps into the pad as you curl to maximize bicep recruitment through reciprocal inhibition.
- Imagine trying to pull the bar toward your forehead rather than your chin to maintain constant tension at the peak of the movement.
Make it harder
- Implement a 4-second eccentric (lowering) phase to increase time under tension and muscle fiber damage.
- Perform '21s' by doing 7 reps in the bottom half of the range, 7 in the top half, and 7 full-range reps.
