Actually, Rick has created a simple and effective self-test to determine if you have a forward head posture. One of it is to check if you have a fatty or bony bump on your upper back at the base of your neck.
Some of Rick's patients have Forward Head Posture that existed for years but after using the product, they have testified that their problem was corrected. But this will vary from person to person.
I suggest that you should do the exercise as demonstrated by Rick for speedy results.
I hope this information has helped you!
