Starting with your feet hip-width apart, step your right foot back as far as you comfortably can, bend your front knee and reach your right hand to the floor. In one motion, pick up your chest, put all your weight on your front leg, and swing your back knee up to your chest while bringing your opposing hand up by your face (like you're running). Once you're comfortable with this, you can turn this into a jump—push off your front foot when you swing your knee forward.
