If you are a girl with weak self-control and plenty of time, I suggest you go to the gym with your friends if you want to practice the vest line as soon as possible. In the gym, you can mainly use two kinds of fitness equipment, one is the waist rotating machine and the other is the abdominal training machine. According to the normal use standards of these two kinds of sports equipment, you can exercise alternately for one hour every day. After a week, you will obviously feel that the meat on your stomach has become a little thick, and after a month, you can see the clear vest line. But only if you can persist and practice every day. If "fishing for three days and drying the net for two days" is definitely useless. Therefore, if you want to practice the vest line as soon as possible, you must stick to it.
If you are a girl with strong self-control and don't have much time to go to the gym, you can practice in your own suitable space. Buy a yoga mat and put it at your work or at home. As long as you have time or are upset, you can do flat support. In fact, this sport is also the best way to practice vest line. Start a group of 30 seconds, and then slowly increase to 60 seconds. Then, you can try one-legged support. If you want to practice the vest line as soon as possible, you must stick to this sport and do it every day when you are free. This method is simple and effective. The key is whether you can stick to it. If you are efficient enough, you may spend two weeks practicing the vest line you want. But this method may make your chest smaller before practicing vest line.
Whether you can practice the vest line quickly depends on whether you can persist. When anything is really done, you will feel that it is not as difficult as you think. The hard thing is to keep going.
