That depends on you.
It is most often down to personal capabilities. It is generally seen to be the stroke, Butterfly, as the most difficult.
Most people say butterfly, but it's different for everybody.
it would be the freestyle the most easiest stroke in swimming
It is the leg's kicking action when a swimmer's doing the Butterfly Stroke. The legs are kept together and moved up and down in a wave-like motion. The Butterfly Stroke is considered to be the most difficult swimming style.
Frontcrawl is generally the most popular swimming stroke as it is the most efficient
the fastest swimming stroke is the butterfly...well it is supposed to be, but since it is such i difficult stroke as well it is harder to swim a long distance well. So the most efficient and fast stroke would have to be freestyle (the front crawl) hope i helped :) The fastest stroke is front crawl, full stop!
the most popular stroke for swimming would obviously be, front crawl. this is why, in freestyle, most people choose front crawl and not back stroke, butterfly or breaststroke.
Typically, the slowest stroke is breaststroke in swimming as it has the most inefficient technique in terms of hydrodynamics.
free style
It is the fastest.
Butterfly is one of the four major strokes used in competitive swimming. The others are freestyle, backstroke and breaststroke. Butterfly is swum as often as backstroke and breaststroke in a normal swimming meet. Butterfly is generally considered the most grueling and difficult of the strokes, so its popularity outside of competitive swimming is limited.
