I am taking a swimming class at my college and learning to swim...Pretty sad, I'm 20 and can barely swim . Our school district does require high school graduates to pass a swimming test (swim about 50 meters and tread for 1 minute) or pass a swimming class. Though I passed the class, I was unable to pass the test... The other day I was watching a video of some guy surfacing by sorta wiggling his body back and forth, I'm guessing this is a dolphin kick. So...today I tried to imitate this in my swimming class. I think it worked to some extent because I was moving by just doing that kick. Is the dolphin kick more powerful than flutter kick? I noticed that I could go further without breathing with the dolphin kick compared to flutter kick. Is it efficient to use that kick with front crawl? I cannot do breast stroke because I haven't learned to breathe with that stroke yet.
