OK, I just came home from the MacKenzie trained PT visit, after having hip pain for over a year.
He told me essentially what this article says, in addition to the fact I now am "leading the flexion addicted life," after mostly standing up all day when I was teaching. My posture kind of sucks, too. But, he talked a lot about how the road bike position just makes this all worse. Now, this guy is a runner, he rides quite a bit, too, and he also x country skis. He didn't tell me to stop, but I am now on the cobras every 2 hours and lots of psoas stretching for awhile, as well as sitting with a lumbar support at home, which will be followed by core work.
Very interesting article.
