Run for more than 30 minutes, preferably about 45 minutes to 60 minutes, because it takes 30 minutes to start burning fat.
Jogging can improve your metabolic rate. I don't think it is necessary to stipulate how long you must run. All you need is a heart rate of about 130 beats per minute. As long as you are not out of breath when running, you can keep running.
Never stretch after running! ! ! Warm up before running.
