This is a difficult area to stretch, but very important for maintaining good postural alignment. Start kneeling on the ground, and step one foot in front. Contract your lower abdominals to tilt your pelvis forward and under. Now lean slowly onto the front foot, and you may already feel a stretch at the top of the hip. If not, try advancing the stretch by keeping good balance, and lifting your back foot towards your bottom. Hold for 10-20 seconds and breathe deeply.
