## Technique

1. Place a preacher bench in front of a low pulley and attach a single D-handle.
2. Rest one upper arm on the pad and hold the handle with the thumb pointing up.
3. Curl up until the forearm is near vertical, keeping the thumb up.
4. Lower slowly until the arm is almost straight.
5. Finish the set, then switch arms.

### Cues

- Keep the wrist straight.
- Keep the elbow planted on the pad.
- Pause briefly at the top; the cable keeps tension there.
