Use the foot on the ground to push your weight into the wall. Engage your abs to tuck your pelvis and even your hips so you feel the hip flexor of the leg on the ground stretch.
Grab a hold of what you can reach- knee/calf/toe. Alternate tucking your head down and lengthening it in line with your spine holding each for 10 seconds
Hold the outside of your foot or leg, (unlike me above). Focus on pushing away from the wall with your foot. At the same time use the foot on the ground, engage your abs, even your hips and twist your body until you feel the outside of your leg on the wall from knee to hip stretch.
