Has anyone had to see a..

I had to go to one because of my insurance. He had me walk for  5 min to see what my heart rate got up to, checked my muscles, my back and my flexibility, showed me some core exercises to do after surgery to help with my stance, gave me a plan with some excesses to start on as soon as I could stand up after surgery and for a few weeks afterwards. He also gave me some bad news that the pain in my lower back probably wouldn't get any better with weight loss :( He did say I was a great candidate for the surgery though and I should be a success. It really wasn't that big of a deal and took me less then an hour.
