BICEPS · PULL
How it is executed
- Sit at the machine with your upper arms resting on the pad.
- Grip the handles and curl up, keeping your arms against the pad.
- Pause at the top and lower slowly, fully stretching your biceps.
- Avoid letting your arms lift off the support.
Common mistakes
- Seat too low: align the elbow pivot.
- Pushing with the chest: let the elbow flexors work.
- Slamming plates on the return: control the lowering.
Frequently asked questions
- How do you adjust the seat?
- Align your elbows with the machine’s pivot and let the upper arms rest on the pad.
- Is it the same as a barbell preacher curl?
- The support is similar, but the machine guides the grip and its mechanism changes resistance through the movement.
- Should the upper arms lift at the top?
- No. Finish bending before you need to lift the upper arms or move the shoulders forward.
