Start in a deep lunge: Start with a plank position then bring your right foot up next to your right hand.
"Drop your back knee to the floor and bring your hands up on your front knee for a good passive stretch in the front of your hip. Place your hands on the floor and straighten your back leg, lifting the knee, for a more active stretch. Hold for at least three deep breaths. Repeat on the other side. For a flexibility bonus, try bringing your forearms to the floor."
