Pilates has helped me in so many ways. My PT recommended it very strongly. I was fortunate to live near a wonderful classical Pilates (and Pilates-only) studio when I started, and worked with them for two years before I moved. Now I continue with what I learned there on my own doing the mat series. Someday I would like to become a Pilates instructor so that I can help people like I was helped. But for now, I continue doing the mat series every other day. The full Pilates studios in my new city are not convenient to where I live.

I think if you get a good classical mat course, you will really notice a difference. Be sure that the teacher understands any modifications that you might need because of your injury. It's different than yoga, but I find them to be useful for different aspects of my fitness.

I'd be interested in what your PT suggests.

(I've also heard jokes about "Pilates butt," but it's true. Nothing wrong with having a nice, and pain-free, backside).
