“Flow” is the lifeblood of taijutsu. If you have good flow you are that much closer to good taijutsu. Good flow comes from moving in a relaxed manner and with as few movements as needed to accomplish the task. As you practice, if you are finding that you just can’t get it, take a step back and try to relax for a moment. Pay attention to any tension in your body and work it away with some junan taiso. Take a few breaths, calm down and give it another go. Nagare doesn’t mean fast, it means smooth.
