What sort of programming did you use to work ok your mobility? I’ve been looking to do the same.
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.
Opening up and releasing my chest, t-spine and pelvic floor has been a long and slow process (8 months so far) but I’m finally relearning proper movement.
