Lever Biceps Curl
- Intermediate

The lever biceps curl provides constant tension throughout the entire range of motion, specifically targeting the biceps brachii. By utilizing a fixed pivot point, it minimizes momentum and allows for a superior peak contraction compared to free weights.

Setup
- Adjust the seat height so your elbows align perfectly with the machine's pivot point (axis of rotation).
- Sit with your chest firmly against the pad and feet flat on the floor for stability.
- Grasp the handles with an underhand (supinated) grip, ensuring your wrists are in line with your forearms.
- Position the back of your upper arms flat against the arm pad.
How to do it
- Exhale as you curl the handles toward your shoulders, focusing on the contraction of the biceps.
- Squeeze your biceps at the top of the movement for a one-second pause.
- Inhale as you slowly lower the weight back down over a 2-3 second count.
- Stop just before your elbows fully lock out to maintain constant tension on the muscle.
Form checklist
- Keep your elbows pinned to the pad; do not let them flare or lift.
- Avoid leaning back or using momentum to move the weight.
- Maintain a neutral wrist position throughout the entire set.
- Ensure your chest stays in contact with the support pad at all times.
Pro tips
- Focus on driving your pinkies toward your shoulders at the top of the movement to intensify the peak contraction.
- Keep a light grip on the handles to reduce forearm involvement and maximize bicep isolation.
Make it harder
- Add a 3-second isometric hold at the midpoint of the eccentric (lowering) phase.
- Perform '21s' by doing 7 reps in the bottom half, 7 in the top half, and 7 full-range reps.
