I plan to enter the professional swimming field. Triangle is the best. I don't drag the water, I can speed up the progress. I can play civil and general in the water. My thighs are thicker and my elastic fibers are thicker. Now you can't wear any swimming trunks, they are all highly elastic. Professional swimming coaches, some should wear a smaller size, tight and powerful, to reduce the resistance in the water.

So what kind of swimming trunks to wear is not a problem, just find the right size.

If you are a professional and want to choose knee-length swimming trunks, then five-point pants are good, hard and can be worn. After getting used to it, I don't want to change the right angle, and dragging the water will hinder the speed.
