Not that I'm particularly badly injured now, but I'm sure at some point in the future I will have to have an enforced lay off. What I want to know is, are there any decent DVDs I could watch to keep me inspired/interested, and give my brain a little food for thought while I can't get in and train? Just watching endless instructionals would be boring, especially if I can't actually try stuff out. I'm thinking more along the lines of a documentary-type film but with enough technique/theory on display to keep my mind actively stimulated. Any ideas?
