Morning running is not good for your health. First of all, the air in the morning has a high carbon dioxide content and a low oxygen content. Second, getting up in the morning, the body's metabolism is still in the primary stage, not as active as in the afternoon. Third, if you want to lose weight, you can keep the muscles of your hips and thighs tense to your calves when you walk, which makes it easier to keep fit. If you want to lose weight, go at night ~ ~ I heard that losing weight is faster than running ~ ~ Just go. Don't exercise at night for 30 hours after eating at night ~ ~ ~ First, you have no time in the morning and have to go to work every day. Second, take a shower after running. If you don't have time to have breakfast at work, you will have no energy at work, which will lead to high blood sugar. Unhealthy. It's different at night. It will be very comfortable to take a bath after running. You can also sleep.
