5 steps to better tumble turns
Forget turning for a while, and go back to practicing forward rolls in the water. Its amazing how hard they can be! Practice getting our head down quickly and trying to roll all the way over without paddling too much with your hands. When you feel comfortable practice swimming front crawl into a forward roll. Aim to get your head down fast and rotate quickly.


Practice spending as little time as you can with your feet in contact with the wall. Once they are planted drive with your thighs as though you were jumping. Don't waste time turning onto your front before pushing off, push off on you back if necessary (Michael Klim did this very noticeably at the Olympics). Some people, such as Alex Popov in these photos, like to incorporate a quarter twist into their tumble so that they push off on their side. This is entirely a personal thing, but may work well for you. Many top swimmers have coaches specifically to train them to be better jumpers and hence get a faster push off from the wall. Practice doing Sergeant jumps to improve your speed off the wall.

Finally remember that whatever you may get from practocing yout turns in isolation, they will not become second nature if you don't remember to turn properly every time you do a tumble - only perfect practice makes perfect!

Try not to stay under water too far as you'll lose speed! -- Nathan
A faster turn is dictated by tucking your head tighter, not by trying to bring your legs over faster. If you tuck your head tighter and faster you can spin aroung your centre of mass a lot faster -- Steve
After pushing off streamlined always pull with the deep arm first and don't breathe for at least two strokes. When you do it right you will surge forward and come up in front of the rest of 'em! --Mammamedley
Never come up too early. Otherwise the wave that was behind you before you turned will hit you causing you to slow down. To avoid this you should stay under water for about 3 hard fly kicks and then break into hard free kick. --Mark
