Thank you, Catrin, for your thoughtful review! I saw the announcement pop up on the mobilitywod site the other day, but wasn't sure if the book would have more/better information than (trying to find it) on the blog. But, following my upcoming knee surgery, I definitely want to get my hips and hip flexors sorted. Thanks to your review, I'll probably go pick it up now; please make sure you get your commission.
