I recently replied to a PAO candidate about "restrictions," saying I don't have any. Of course I was told not to do lunges ... but I do them in my yoga class and on the ice, as well as lunge-like moves like hydroblades. I do squats daily to keep my quads strong (this is fairly new, but I needed to do it and it hasn't hurt my hips -- it has helped my knees). I do an occasional jump on the ice, and I run now and then to get from point A to point B.
I do all of these things within reasonable tolerances and with an eye toward any hip pain that might ensue. So far it doesn't, and I'm careful because I do want to protect my PAO investment. I don't feel like I have any restrictions because in daily life I don't think about movements I can't do, and I don't specifically limit myself. My flexibility isn't what it was but that's a limitation, not a restriction.
Stay tuned for my adventures with trekking poles in a future post.
