Hehe, the question you asked is very cute. If you want to exercise to lose weight, you can do it at any time of the year, but it is more convenient to lose weight in summer than at other times, because high temperature can help us get rid of excess fat in our bodies faster. There is no need to wear cotton-padded clothes for exercise. Sitting there in summer in this weather will make you sweat, let alone exercise. In that case, it will be easier to dehydrate, but it is not good for your health. You can do some aerobic exercise in summer, such as swimming and long-distance running. If possible, you can go to the gym to find a fitness instructor to make a professional fitness diet plan, which can achieve twice the result with half the effort!
