Concentration Curl
Seated, elbow braced on the inner thigh; curl the dumbbell up and lower slowly.

How to do it
Setup
Seated, elbow braced against the inner thigh, dumbbell hanging; other hand on the other knee.
Steps
- Curl the bell toward the shoulder.
- Keep the elbow pinned to the thigh.
- Lower slowly to a full hang.
Common mistakes
Elbow sliding off the thigh: re-brace; the pin is the exercise. Leaning back to finish: the torso stays still. Fast drops: the slow lowering is the growth half.
Breathing
Exhale on the curl, inhale lowering.
