Shinji Takeuchi's "Most Graceful Freestyle" video is one of the most viewed swimming videos of all time. His so-called "Total Immersion Technique" is incredible to watch, as he makes the stroke seem so effortless. The use of a prolonged glide phase, minial kicking and deeper body position in the water goes against traditional swimming technique, but the effectiveness of his technique is not to be questioned. Some of the best long-distance swimmers in the world have a similar "catch-up" stroke, only slightly less pronounced. Efficiency in swimming is all about minimizing drag. Therefore technique is such a critical piece to the puzzle.
