If you count the calories consumed by swimming for a few minutes or one or two hundred meters relatively accurately, then the calories consumed by swimming for an hour will be very different, because it involves many factors such as weight, posture, speed, etc., and the influence of different postures is very critical.

Butterfly stroke is the most tiring posture. If this posture can last for an hour, it is definitely superman, and the consumption of 1000 calories should be almost the same. When swimming freely, you can also breathe freely and relax all over, consuming less than half of the calories. The following is a-1 hour swimming-approximate consumption statistics.

Swimming (butterfly) 938 kcal

Swimming (freestyle) 623 kcal

Swimming (optional) 402 kcal
