If you just want to walk slowly, it is more appropriate to adjust the speed to 4 km/h-6 km/h. This kind of walking is generally suitable for walking after meals and relaxing after exercise.
If you want to achieve better fat-reducing effect through the treadmill, you'd better adjust the speed to above 8 km/h.
After the warm-up, start running. Friends who don't usually exercise much suggest walking at a speed of 5.5 for 5 minutes and jogging at a speed of 7 for 5 minutes. In this process, pay attention to whether the heart rate exceeds the highest heart rate of aerobic running. Once you exceed it, you need to slow down.
Friends who usually have exercise habits can start jogging, jogging at a speed of 7 10 minute, and then walking at a speed of 5.5 for 3 minutes. They also need to observe the trend of heart rate, and they need to slow down if they exceed the maximum heart rate of aerobic running.
