BUTTERFLY

The butterfly is a relatively young stroke. The butterfly stems from the breaststroke, because the contramovement of the armsare executed above the waterline. The pull through of the arms was extended in the direction of thehips, while initially the legstroke of the breaststroke was maintained.

The Armstroke
The arm-movement contributes in large amounts to the speed you swim:- There can be brought a lot of power in it, because you pull your arms through at the same time.
- The pull through is a long movement, from far before to close to the hips.
- The damsurfaces can be placed in a favourable position, which is similar to the arm
-movement of the freestyle.
- The pull through is completed with both arms at the same time, through which deviations in the straight line are exceptional.
- The pull over is above the waterline, through which the resistance is reduced to a minimum.
The armstroke can be divided in the following phases:-
Put in-phase- (Short) glide-phase- Pull-phase- Push-phase- The Lash out- Pull over
