Technique- flip turn, body movement

The front crawl uses the tumble turn, now called a flip turn.  It is used to reverse the direction in a small amount of time.

Above is a video of the girls 13-14 50 yard freestyle event.  It shows a flip turn after 25 yards so that the girls can quickly reverse and continue swimming.

The position of your body during freestyle swimming is very important. Your shoulder of the recovering arm should always be higher than the shoulder of the pulling arm.  This makes the recovery way easier, in other words, you'll feel super smooth in the water! While one shoulder is out of the water, it lessens drag, and when it falls, it helps the arm catching the water. As other shoulder rises, it aids the arm at end of the pull to exit the water.
