Not necessarily. If you go to the gym to play, you can't; But as long as you practice hard, you will lose weight and get better. If you need to lose a lot of weight, I suggest you exercise three times a day, around 9 am and after 4 pm, which can effectively lose weight; After dinner 1 hour, run for 30 minutes, skip rope or something, and replenish water when you go home without eating. 1 month, 10 to 15 kg is certain.
