Intermittent rest is effective. People have to exercise continuously for more than 40 minutes before fat starts to burn. The best way to lose fat is to extend the exercise time as much as possible. Try interval training, divide the exercise plan into several sections, and have a rest before exercise. For example, practice at 7 km/h for 2 minutes, then at 5 km/h for 2 minutes, and then return to 7 km/h for 45 minutes.
