From Chair Pose, take a deep inhale in. Then on your exhale, cross your left elbow over to your outer right knee. Press your palms together, and actively push your bottom elbow against your thigh to lift and rotate your chest up, increasing the twist. Pull your right leg back slightly, making sure both knees are parallel.
Stay for five breaths. Then inhale as you press into your feet and lift your torso, rising back into Fierce pose. If you can, refrain from straightening your legs to keep your quads and glutes engaged.
Exhale to cross your right elbow over your left outer knee, holding for another five breaths on this side.
