My flip-turns... not yet perfect
My next goal for swimming to save more time is to do proper flip-turns. See also: http://www.svl.ch/flipturn.html
Great hint: "•Never use your arms and hands to initiate and perform the tumbling motion (mistake #1)." - I trained it without arm-movement and it is much more smoother!
