Thanks for this sound advise.

I've started doing short walks actively focusing on abdominal contraction - this works well. Also recently I've started using a Spinalis chair at work. This forces you to do core stability all day - very expensive (around £800) but I would recommend.

I've been experimenting with a number of ideas lately - one thing stands out as having had a miraculous effect on my left hip which has got in a total mess: the Supine Groin Stretch which is part of the Egoscue method.

This has left me a bit confused: I've done a search on this forum and the word Egoscue only comes up once.
