Here is a great flow drill from Iain Abernathy showing an introduction to a flow drill from the start of a Pinan kata. He does fantastic work in bringing kata from the world of theory into the world of practice, unlike many I have known. I think it was Marc MacYoung who said, “The difference between theory and practice is that in theory, there is no difference.”
