Personally, I prefer freestyle. You can see for yourself and then decide which one to study.
3, freestyle is more laborious, it should be thinner!
4, the time is free, but it must be more than 20 minutes.
Individuals usually swim at night, because it is easy to tan their skin during the day (water reflects sunlight).
6. Um ... I usually go swimming when I have time! ! ! If you want to lose weight ... 3-5 times a week should be enough ~
7. Go swimming as long as you have time ~ Don't waste it ~ ~ Persistence is victory! !
PS: You ask so many questions ~ ~ Tribal Tiger ~ ~ I'm exhausted ~ ~
