Doing exercise in the morning is also good, which can make you feel refreshed all day. If you have exercised, you can do fifteen in a group and five in a group. Of course, this is a suggestion. When doing sit-ups, you can straighten your legs or bend your legs. When you get up with your head in your hands, your head touches your knee. Once in the morning and once in the evening, keep the perseverance of kicking your stomach away and try to drink as little as possible.
