Yes, you can. In fact, where there is not much difference, the focus is on persistence. Combination of diet and exercise. The advantage of the gym is that it is easier to participate in group sports and be driven by everyone. In addition, there are some tools for men's words. You can also focus on reducing the corresponding parts according to your own situation. Muscle training itself is a process from fat to muscle. The meat becomes tight and looks thin and masculine. What's wrong with boys doing this? But the gym definitely costs money. It depends on your own situation. There are many people in the square in summer, but they can actually blend in with everyone, and I believe that increasing personal time for exercise alone can also be effective. In terms of diet, we must ban greasy and high fat. In fact, insisting on exercise is one aspect of losing weight, but it is healthier. Only healthy people can keep fit. Personally, I suggest that you make exercise a habit, not just to lose weight during the summer vacation. I wish you success in your practice.
