I like the butterfly storke
The butterfly stroke is driven by the chest!
i have heard that when i was in school
The first official swim was in 1933.
o really? where did it take place
I am not so sure, but the breastroke is a favorite since 1933.
yeah i can imagine!
The butterfly is a more expert and difficult stroke than the others
What are the others?
Backstroke and crawl.
