Make a detailed exercise plan during the holiday. For example, run 5 kilometers every morning and then do some flexible activities. In short, let yourself sweat, don't hesitate to sweat. Run at least 5 kilometers after 6 pm, and then do some sports you like. At the same time, keep your diet and don't increase your usual diet, because the weather is hot and you eat lightly. As long as you keep exercising for at least two and a half months every day, you will have obvious effects. I also don't know if you are overweight. If it's not pathological overweight, and you don't have to deliberately reach how much weight, the standard is good. If you insist on taking a vacation, you will fail on purpose.
