Proper exercise is not just doing exercise. In daily life, you must do what you should do every day and don't be lazy.
Don't leave it to be served, and don't sit or lie down as soon as you finish eating.
If you are energetic, do some stretching exercises properly.
Remember to overeat, eat irregularly, adjust the diet structure and eat less sweets.
Generally speaking, it is better to walk than to sit, not to sit or lie down. Of course, if you are tired, you should change it appropriately.
