Concentration Curls
Biceps · Dumbbell · one side at a time
How to do it
Seated, elbow braced against the inside of your thigh, arm hanging. Curl slowly to your shoulder rotating the palm and squeeze at the top; lower to a stretch. The brace removes any cheating, so it is pure biceps with light weight. You feel the peak of the biceps. It is a finisher, not a loading exercise.
