Training is as training does. If you want to develop speed, you must train fast. If you want to develop ki, you must train for it. If you want to be a good defensive martial artist, you must spend time defending yourself. No b.s., real time training. Full speed, full power, full contact.
One of the most accurate statements made about training in some time --- and, unfortunately one of the most ignored.
Very well said Mr. Linden, and from what I gather, very well lived.
