About 2000 a month, which is more expensive. Personal advice is mainly to control diet;

1 Go to the gym to learn aerobics and get in shape (this is aerobic exercise, which can consume a lot of fat, and it will be effective as long as it lasts for one month). There is no need to hire a fitness instructor! I saw those fitness instructors in the gym. They gave you some rules about exercise and diet, wasting money. 2. Go to the treadmill for exercise. In fact, we still need to persist. It's not worthwhile to spend money on a coach. Of course, with the help of the coach, he will supervise you to finish some fitness exercises when you go to the gym, so if you can persist, don't look for a coach for the postgraduate entrance examination.
