Now there is nothing magical or mysterious about the TI system. Much of it is just a solid technique, swimming, the other well-known for a long time (eg, downward rotation, body firming, etc). But there are other aspects that seem to be unique to TI. If the system really shines is in the gradual approach and skill-specific exercises to build a smoother and more efficient stroke. It is down, broken, so logical and systematic way that one can not help to improve but at a freestyle stroke, by simply trying to run his lessons.
