I highly recommend Dr. Kelly Starrett for all things mobility. Thereadystate.com (his website) is my daily source of mobility instruction, both for daily mobility work, and for getting me through many an injury. Reading the Supple Leopard (his book) is useful, but it’s hard to beat the follow-along videos for usefulness.

Plus, he’s a huge Dune nerd, which comes through in occasionally hilarious ways.
