The other day just walking down the road with BaldyBoy, he said to me "you know, your posture is really very much improved since you've been running" I asked if he could tell me when this improvement became visible, he said the biggest difference came last year after I followed Bazza's "circular legs" advice, and there has been another step-change recently, which I put down to TurnTurtles "Parasail" advice.
This is an unexpected benefit from running, I have scoliosis and a herniated disc, so didn't really think I would be able to run any kind of distance, in fact I've had almost no problems with my back since I started C25K last year. Swimming, on the other hand, which was recommended to me by my osteopath often left me twinging afterwards. I wonder what my osteo would say about the running, I haven't had a chance to tell him as I haven't seen him for (The saving on his fees have probably paid for my shoes lol)
