How were you diagnosed dude?
I haven't been consistent enough to say - and I'm not sure if the reason I have it is due to muscles not firing properly, or structural issues which won't go away. I've had the clicking in my groin since I was a teenager, but then again I've also spent a lot of my life sitting on my ass which can't have helped the glutes.
Anyway, the book is split into 3 sections: Tissue work (foam rolling, self myofascial release) Stretching (static, long holds), and Reactivation (active stretching) It's generally all stuff that you can find online by googling, but it did have some exercises I hadn't heard of, & it's nice having the program set out for you.
