I whole heartedly second this recommendation. This is from Diamond Dallas Page (I believe that was his wrestling name, I'm no fan of Pro Wrestling, I'm afraid) who had major compression of multiple spinal discs, almost unusable shoulders, hip issues and knees that were destroyed. He started yoga exercises without the "woo woo" and has brought a lot of the functionality back to his body.

He has gone on to rehabilitate multiple people and document it. It's really a fascinating story. Kudos!
