How to do the Lever Preacher Curl (Version 2)
BicepsMachineBeginner
The lever preacher curl machine locks your upper arms in place so your biceps do all the work with zero cheating, making it one of the most effective isolation tools available to beginners and veterans alike. Master this movement and you will build consistent, measurable bicep strength from a fully stretched position through peak contraction.

Step-by-step
- Adjust the seat so your upper arms lie flat along the pad with your armpits just touching the top edge, then grip the handles with a supinated palm-up position.
- Curl the handles upward in a smooth arc, squeezing your biceps hard as your hands approach shoulder level without letting your elbows lift off the pad.
- Hold the peak contraction for a full one-count before beginning the descent.
- Lower the weight slowly over two to three seconds until your arms are nearly straight, keeping tension on the muscle throughout the entire range.
Common mistakes
- Sitting too low so the elbows lift off the pad during the curl, which shifts stress to the shoulders — raise the seat until your upper arms stay fully supported at all times.
- Letting the weight crash back to the bottom, losing the eccentric phase entirely — control every rep on the way down to maximize muscle stimulus.
- Using a weight so heavy that you shorten the range of motion and never reach a full stretch at the bottom — reduce the load and commit to complete extension on every repetition.
Pro tip — At the bottom of each rep, consciously resist the urge to let the machine fully unload your biceps — stop just short of lockout and maintain a slight tension to keep the muscle under continuous load and protect the distal tendon from sudden stress.
