Anchor band low around something stable. Hold band in hand opposite of working leg. Find your balance, keeping lifted leg LOW so you can focus on maintaining form on standing side. Make sure shoulders (especially one holding the band) don't roll forward/diagonally. Hinge from the the hips, keeping hips square (non working side will want to rotate open), weight in heel/mid foot. Keeping weight there, contract from glute/hamstring to come back up. Focus on external rotation of the hip and glute.
