Usually when you get up in the morning, I don't recommend doing anaerobic exercise immediately, because your nerves and muscles are still hibernating and haven't woken up. And as far as my limited fitness knowledge is concerned, I suggest adding some carbohydrates before starting exercise.
Then if you are a girl, you can drink a cup of warm honey water first, and then start exercising. Of course, glucose water can also be used. I bought it, but it's not as good as honey water Now there are more than half of cans left there. Most girls have a little hypoglycemia, especially when they exercise on an empty stomach in the morning. If it is a boy, you can also add a small banana appropriately. A former Russian friend of mine especially liked bananas before exercise.
Generally speaking, the duration of aerobic exercise after getting up is about 10 minutes to 15 minutes. After fully activating your muscles, anaerobic exercise begins. This can avoid injury, especially in cold winter. If you don't exercise your muscles sufficiently, you will get hurt easily. It is better to pay attention to your old arms and legs. In addition, from the current theoretical basis, it is indeed better to gain muscle without oxygen after aerobic exercise. Of course, if you are reducing fat, you should do aerobic exercise for about half an hour after anaerobic.
But if you can persist, the exercise effect in the morning is still very good, and you can be energetic all day. If it doesn't work, it can be changed to evening. The most important thing in sports is persistence. I wish you early results.
