Half Moon Pose anatomy
Half Moon Pose · Ardha Chandrasana · Tư thế nửa vầng trăng
Half Moon Pose mainly works quadriceps, gluteus medius, tensor fasciae latae (left), gluteus maximus (left); it stretches hamstrings (right), adductors (right), pectoralis major; gluteus minimus (right), tibialis anterior (right), tibialis posterior (right) stabilize.

Opening the 3D model…
Balance on one leg with the same-side hand on the floor or a block and the other leg lifted to hip height; the torso and pelvis open to the side as the top arm reaches up. The gluteus medius on both sides works hard to keep the hips stacked.
