Technique
Lay on your good side. Be sure your position is the top hip over the bottom hip without being rotated backward or forward. Keep knees bent at a right angle with your feet together.
Your feet must be kept in contact with one another. Raise the top knee up off the bottom knee as far as it will go comfortably.
Do not roll your hips backward to gain more hip movement.
Be sure your lower back and pelvis are unmoving for this procedure.
Slowly lower the knee down. Rest a bit and duplicate what you just did possibly raising higher this time.
Anterior pelvis tilt is another hip problem that must be corrected. This condition results in gluteus maximus inhibition caused by an anterior pelvis tilt resulting from tight hip flexors. Tweaking of these flexors will greatly increase hip performance
