I'm glad someone asked this. Before I spend the time on an exercise/stretching routine I want to get some assurance that this will have some effect/payoff.
Unfortunately the fitness and health realm is so filled with charlatans and just sloppy thinkers that one cannot help but to be skeptical.
Unfortunately, I can't say that I have a success story, but I can confirm that this is typical advice, in line with what a very good physiotherapist would give you. I read this and it corroborates everything I am supposed to be doing (and describes my symptoms exactly). Here's hoping it is actually successful advice too.
