SUPTA PADANGUSTHASANA Reclining Hand-to-Big-Toe Pose
Begin by lying supine on your mat. Exhale as you lift one straight leg up, moving into hip flexion. Catch the big toe with your fingers, or hold your outer ankle or lower leg if your hamstrings are tight. This action, moving against the force of gravity, is created by the hip flexors undergoing a shortening contraction against gravity.
