Re the two negative reviews here, a couple comments. First, when constructing a menu now, static back should only last about 5 minutes. Supine groin stretch is, on average 10 minutes a leg, not 45. Now if your groin muscles are so locked up that this doesn't do it for you, you may need to increase that time to break through, but only for a short time. Does doing menus take time? Yes, it does. My average menus are 45-60 minutes. Is it worth it? Absolutely.
Re the clinic not providing free help, there is nothing they can safely do over the phone without having already seen you. To provide a menu 'cold' like that could harm instead of help. Once they've seen you and worked with you they are excellent and responding via phone and have given me plenty of free advice. They need SOMETHING to use for diagnostic purposes.
Anyone who thinks light stretching does what this method does clearly doesn't understand the method.
