I’m a swimmer so I know most of this but I have no clue what the side stroke or front crawl is, I’m guessing freestyle? But in short, swimming works out the entire body and it a great skill to learn. Breaststroke is one of the slower strokes and has a big kick, butterfly is the hardest because it takes much more force and is tiring, backstroke is difficult for some but easy to learn.
