Come into a half-kneeling position with your left leg elevated. Keeping your torso upright, place your hands on your hips with your thumbs resting on the front of your hips. Use your hands to help tilt your pelvis forwards, tucking your hips underneath your body into a posterior pelvic tilt. Squeeze your glutes to feel the stretch in your hip flexors. This is your start position. To deepen the stretch drive your hips forward but be sure to maintain a posterior pelvic tilt. Hold for the recommended amount of time, then repeat on the other side.
