Hello! This is me in a training section of my butterfly, yet screwed up my diving since my legs werent straight so it looks retarded and funny xD Videos Uploaded In YouTube http://eddywu.wordpress.com/eddy-swimming-videos/ * Beware * I AM NOT A GOOD SWIMMER and improving daily
Off course they go faster, more water movement.. And with the Butterfly, try not to splash to much with your feet, seeing it will only force water up and not backwards (The opposite way of which you swim in, resulting in thrust which results in speed) so you get more forward movement instead of lots of water going up. As you can see in this video the people who can do it almost perfectly (This is not that I'm saying you can't do it good, but they have just perfected it by training like 9 hours for 6 days a week probably) they have way less water splashing up. http://www.youtube.com/watch?v=eizzEnCTaU0
