My swimming is coming along slowly (from virtually nowhere when i started) to the point where i can swim 1500m crawl in the pool.
However i am still not tumble turning. I tried doing it last night at the end of my session and didn't make a very good job of it i.e. bad timing, positioning water going up my nose and surfacing way too early and losing speed.
This of course is a very long-winded way of asking if anyone has any tips on how to perform a good tumble turn?
