Hi Mark,
I noticed your remark about how rowing hurts like hell. I have been rowing since 1964 in college. In 199, I first noticed a pain in my right hip which gradually worsened and moved into the spine over the next ten years. I was finally diagnosed with AS in 2001. I still row because it is the only exercise I really enjoy and can tolerate, probably because I have done it for so long. I does hurt sometimes, but overall, I feel better after an hour of light rowing, and some days even feel good enough to compete again.
I recommend rowing for AS sufferers as a form of exercise, but if you don't row correctly or do it too forcefully, it will be painful or impossible to do. I also feel better the next morning after rowing. Just thought it might help some one.
