Why people do the butterfly stroke in swimming

‌
Athletes do it because it's their specific event,
but speaking from the perspective of an amateur:
1. GOAT status for short-term exercise volume
Even if you're doing the same workout, if you do butterfly, even the veterans will be exhausted after just 10 minutes.
It's manageable if you take it easy, but coaches won't let you get away with that, haha.
2. Regardless of anything else, it looks the coolest
If you show other swimming strokes to regular people,
there isn't much of a reaction compared to other hobbyists,
but if you show them the butterfly, the reaction is totally different.
It's not just a polite reaction; they actually go "Oooooh~" with a genuine reaction.
Additionally, for beginners and intermediates, the butterfly is the stroke they look at with envy.
I've talked a lot,
but it's simply because it's the best in terms of style among the four strokes, haha.
