Lazyblogging, but not quite. It’s just that I firmly believe that everyone involved in pretty much any kind of training and self-defence training in particular should read this.
I have nothing to add to it, beyond advising people to look for training programmes that respect these criteria and run the fuck away from programmes that don’t. You only have one body and one life. Paying people to fuck either of them up “for your own good” is neither big nor clever.
