The preacher curl isolates the biceps, with the back of the arms resting on an inclined desk.
Seated at the preacher bench, place the back of your arms on the pad, armpits against the edge, and grip the barbell or handles palms up.
Bend your elbows to lift the load toward your shoulders, then lower slowly almost until your arms are extended.
Control the end of the descent: that is when the elbow is most vulnerable.
