Now you want to make sure that you are placing the inner thighs together, squeezing nice and strong. Lengthen out through the crown of your head; pull your shoulder blades back. Now we're really going to focus on the lower back and the glutes here. So inhale to prepare, exhale, lift your legs and inhale lowering down. Exhale lift your legs and lower down, and lift up, and inhale lowering down. Now you're really going to feel this burn in your glutes and you're back is going to feel really great with this exercise.
