Biceps Leg Concentration Curl
Seated with the elbow braced on the inner thigh, the hand hooked under the other leg's shin: curling the arm lifts that leg, so the leg is the load.
How to do it
Setup
Seated on a stool, one elbow on the same-side inner thigh, that hand hooked under the other leg's lower shin, the leg relaxed.
Steps
- Curl the arm to lift the relaxed leg, knee rising toward the chest.
- Keep the elbow pressed into the thigh.
- Lower the leg slowly; switch sides after the set.
Common mistakes
Lifting with the leg's own muscles: keep the leg loose so the arm does the work. Elbow slipping off the thigh: re-brace it. Leaning back to help: stay tall over the stool.
Breathing
Exhale on the curl, inhale lowering.
