Personal Trainer - to loosen my muscles

Felidae_1981

So I've had my first of three free PT sessions at my gym (Gold's). Since the first session is eval only it was not daunting, but extremely painful. He tested my muscle tenseness and found I have very tight muscles. I do have issues with my right hip when running and doctor noted X-rays as unremarkable ... PT says this is due to problems with my muscles. He wants to work on this... And my posture in general, which admittedly is crap.
He says this will help me be able to work harder and achieve my goal of losing about 20 lbs and tone.
Anyone has experience with this? Any PTs maybe?
And I like him ok except that he invades your personal space when talking to you (i get it's necessary during exercises). I'll have to tell him to back off. Or I might switch before I start paying...he'll have to prove himself in my next two sessions
