Loop a long resistance band around a secure anchor point close to the floor. Facing away from, and ensuring a good distance between yourself and the anchor point, come into a half kneeling position with your left leg elevated. Step into the other end of the band with your left leg and position it just below your ankle joint. There should be a good amount of tension on the band. This is your start position. Resisting against the band's tension, push your shin forward as much as possible whilst still keeping your left heel on the floor. Hold this position and repeat on both sides. Repeat for the recommended amount of time.
