Everyone knows that swimming is a great way to burn calories, but most don’t realize it can be just as efficient as jumping on the treadmill. Depending on the stroke you choose and your intensity, swimming can burn equal or greater calories than running.

Additionally, you don’t have to worry about sweat in your eyes. For example: for 10 minutes of swimming you burn 60 calories with the breast stroke, 80 calories with the backstroke, 100 calories with freestyle, and an impressive 150 with the butterfly stroke.

For perspective, running a 10-minute mile burns around 100 calories. Therefore, a strong 30-min butterfly speed session can burn 150 more calories than running a 5K in the same time frame.
