Hi - the last post was very informative!!

ok, firstly, good luck with that physio - it is ALWAYS good to get multiple people with relationship to each other telling you a physio is good.

With your exercises, sometimes it is not the exercise prescribed but HOW it is DONE that counts. A skilled teacher and a patient client are required.

You back with the arch and the tummy sticking out thing - is it a "hyperlordotic" back?

Another possible casue is that there is something causing your lower back muscles to be overactive or to become short. This can affect your breathing/thorax, L/S, Wikipedia reference-linkSIJ, hips etc.

If this guy you wil be seeing is any good, he will explain it all to you.

Sounds like you are on a good thing - keep that determination up!!

Cheers
