Inhale and lift your legs up towards the ceiling while keeping them together, then continue to lift them over your head as you exhale, rolling your weight onto your shoulders.
Keep your hands on your lower back for support as you try to straighten your legs and point your toes behind your head.
Inhale and bend your legs slightly, then exhale and slowly roll your spine back down onto the mat, one vertebra at a time, keeping your legs straight and lifted.
Lower your legs back down to the starting position and repeat the exercise as many times as desired.
