<font color='#0000FF'>Hi
Just a generalisation. My interpretation follows;
We are traditionally taught the flutter kick, which means our legs are pretty much straight. If you imagine your body as a seesaw then you can see that a lot of the weight is on the upper part of your body. Your head (6lbs negative) your tanks, your weights etc. which, as your body is pretty much straight will tilt the seesaw head first. To counteract that it is a natural tendency to angle the body upwards in a diagonal type trim, which I call diving vertical, with reference to my own opinion on my diving and many other divers I see. The seesaw still wants to tip head first and so the diver must continually kick to keep heads up. As the flutter kick produces downward energy you will swim upwards and so you will always need to kick to stay at the same level. A pronounced version is watching a novice diver, whos kicking like buggery and also moving their arms about to stop their head hitting the dirt! This is until they find that the secret is to keep shoulders up and knees down and establish their own balance. The only way to stop is to go vertical. It can't be helped if you use a flutter kick. When you add ankle weights to solve the floaty feet complaint to the equation it increases this tendency even more. Just follow a flutter kicker for a while and then follow a GUE/DIR diver and see the difference. To me it was night and day.
GUE teach that the back is arched, head resting against the valves, and a frog kick used with bent knees therefore producing a kick which thrusts horizontally. By changing the angle of your shins (which have the benefit of heavy Jet fins)and head you can achieve a truly horizontal position in the water. Arching your back brings more of the weight to the middle of the seesaw. GUE also place a great emphasis on placing the weight in the right place to facilitate a completely motionless horizontal hover. Thats why backplates and vweights are preferred and the tanks are placed lower in the bands. The hands are also used to blance the seesaw and this results in what I call the DIR prayer position (praying to the great god wakulla

) (I can and do laugh at myself)
It wasn't meant as an insult, just laughing at myself as to the type of diver I thought I was, and how I saw myself on video. I related that to Twix to help him in his question.
Kindest Regards
