Reverse-Grip Concentration Curl
Seated concentration curl with the palm facing down; the brachialis does what the biceps normally would.

How to do it
Setup
Seated, elbow braced on the inner thigh, palm facing DOWN.
Steps
- Curl the bell toward the shoulder, knuckles leading.
- Keep the elbow pinned to the thigh.
- Lower slowly to a full hang.
Common mistakes
Grip rotating to palm-up: the overhand IS the exercise; it hands the work to the brachialis. Elbow sliding: re-brace. Same weight as the regular version: go lighter.
Breathing
Exhale on the curl, inhale lowering.
