Exercise guide

Lever Preacher Curl Plate Loaded

  • Intermediate
  • Isolation
  • Rep-based
  • Upper arms

The lever preacher curl provides constant tension throughout the entire range of motion while the bench stabilizes the shoulders to isolate the biceps. This variation is particularly effective for targeting the short head of the biceps and emphasizing the peak contraction.

Muscles worked

Primary

  • Biceps

Secondary

  • Forearms

Equipment

  • Leverage machine
  • Weight plate

Setup

  1. Adjust the seat height so your armpits rest comfortably against the top edge of the preacher pad.
  2. Sit down and place your upper arms flat against the pad, ensuring your elbows are perfectly aligned with the machine's pivot point.
  3. Grasp the handles with an underhand (supinated) grip, keeping your hands shoulder-width apart.
  4. Plant your feet firmly on the floor to create a stable base.

How to do it

  1. Exhale and curl the handles toward your shoulders by contracting your biceps, ensuring your upper arms remain glued to the pad.
  2. Squeeze your biceps forcefully at the top of the movement for a one-second pause.
  3. Inhale as you slowly lower the weight back to the starting position using a controlled 3-second tempo.
  4. Stop the descent just before your elbows fully lock out to maintain constant tension on the muscle.

Form checklist

  • Keep your armpits tucked tightly against the top of the pad throughout the set.
  • Avoid leaning back or using your torso to swing the weight up.
  • Maintain a neutral wrist position; do not let your wrists curl excessively toward you.
  • Ensure your elbows do not flare out or lift off the padding during the contraction.

Pro tips

  • Drive the back of your triceps into the pad to create a stable anchor, which increases the leverage and force production of the biceps.
  • Focus on the 'pinky-up' sensation at the top of the movement to maximize supination and bicep peak activation.

Make it harder

  • Perform the eccentric (lowering) phase over 5 seconds to increase time under tension.
  • Execute the movement unilaterally (one arm at a time) to focus on the mind-muscle connection and correct strength imbalances.
