Hello, I'm a girl of 95kg,1.65m. I always insist on swimming in summer, feeling that I can get rid of excess meat in winter quickly, which is more suitable for summer than running and other sports, and my muscles are not painful. I feel that there are not many muscles on my legs and my figure is very tight. What you need to pay attention to is not to widen your shoulders. I just have a little wide shoulders. My leg is fine. I really don't see any muscles. If it's freestyle, my arm will have a little muscle. If you want to stovepipe, I still suggest breaststroke. Upper body movements can breast enlargement, and leg movements can thin thighs, which is very effective. If you want to practice your calves, you can do backstroke and your arms will be thin! I still think it is very effective. Generally, you can see the effect after swimming for 20 days.
