How to do it
- Set the preacher seat so the upper arms lie flat on the pad from armpit to elbow.
- Sit with the chest against the support and a dumbbell in each hand, palms facing each other.
- Let the arms extend until the elbows are almost straight, wrists neutral.
- Curl both dumbbells toward the shoulders by bending only at the elbows.
- Squeeze at the top without lifting the upper arms off the pad.
- Lower under control to the stretch and repeat.
Common mistakes
- Letting the elbows slide up the pad, which shortens the range the arms actually work.
- Locking the elbows hard at the bottom, which dumps load onto the joint.
- Twisting the dumbbells into a supinated curl mid-rep, which drops the hammer bias.
- Heaving the torso off the pad to start the weight, which turns an isolation into a cheat curl.
