Do 100 push-ups every day What will happen in a month?

Push-ups generally have different arm positions and slightly different muscles. But most of them exercise pectoralis major, shoulder and back muscles. Stick to it for a month and the muscle density of these muscle groups will definitely increase. The intuitive feeling is that the muscles of these muscle groups will become stronger when you touch them. If the intake does not change, your body will improve slightly and you can stick to it. If you practice parallel bars in some parks, you may be an expert in street hygiene.
