Treadmill, of course. Exercise 10-20 minutes is a good way to save time. Warm up on the treadmill at a speed of 4-4.8 km/h for 5 minutes, and then increase the speed by 0.3 km/h every 2 minutes until you feel that it will be challenging to keep exercising at a certain speed for 45 minutes. Walk at a fixed pace for about 1 km, and record the time spent. This may take 15-25 minutes. Walking at a speed of 4.8 km/h, the distance of 1 km takes about 20 minutes. After you can do this several times easily, you can gradually increase your speed, so that you can get a good exercise for 30 minutes. Before you finish the exercise plan, be clear in your heart: don't be impatient. This kind of exercise is for one's own health, not an overnight magic.

Exercise frequency: the target is 3-5 times/week, and each exercise is 15-60 minutes. It is best to make a good exercise schedule according to your physical condition, not to exercise according to your own preferences. You can master the intensity of exercise by adjusting the speed and exercise time.
