Under normal circumstances, it is impossible for a fitness instructor to lose a few hundred dollars. After all, a private lesson costs hundreds of dollars, even if there is a routine! However, from my own personal experience, I really can't go too far in losing weight. I have to choose a method that suits me and do it under the guidance of professionals. I started to lose weight in the gym, but it didn't work and I couldn't keep it up. Then, because there was too much exercise in front, I immediately rebounded as soon as I stopped, which was too painful. Then I went to Shapingba Hantang to lose weight, which is a professional weight loss institution. I succeeded in losing weight and shaping, and the environment was too painful. Anyway, since then, I think it is really impossible to exercise to lose weight without self-control. I hope my personal experience can help you. I hope my answer can solve your problem.
