What if the girl just started going to the gym and her arm is gone?

If you just want a thin arm, you'd better hire a personal trainer who will teach you to lose weight accurately.

Many girls think that they must go to the gym to lose weight, and then they can lose weight by choosing instruments according to their feelings. In fact, they don't know that using instruments can not only lose weight, but also affect their health.

If you go to the gym just to lose weight, it is recommended to ask for a personal trainer. Personal education should start from simply increasing arm strength (including increasing aerobic exercise and assisting small devices). When your arms are strong, you are allowed to go to the machine to lose fat and gain muscle. Using the machine can make you lose fat in a short time, but it will be more hard. Don't use the machine foolishly, or you will get hurt easily.
