Mr. Zhao, a reader in Beijing, asked: Coach Jinshan, a master of sports physiology at Ohio State University, replied: In fact, this kind of propaganda is exaggerated. I think liposuction machine should be renamed as waist vibration massage machine. I used this massage machine when I was in Korea. After exercise or sitting for a long time, you can go up and do a vibration massage for a while. After use, I feel more relaxed and comfortable at the waist, but my heart rate has not changed. This massage machine can relax the muscles of waist, buttocks and thighs and promote blood circulation. But because the body does not take the initiative to exercise and does not consume energy and fat, it is useless to lose weight. If the skimmer is useful, the full-body massage chair should be more effective. If you are looking for a magic way to lose weight, just eat less and exercise more. You actually know the true meaning of losing weight, but smart businessmen always induce you to try shortcuts. Statistics show that only 2% of people who have tried to lose weight are really successful and can persist. Most people just lose weight for a while, and then they lose weight. Once they stop working hard, their weight will rebound back to the original level, and may even exceed the previous level. To judge whether a weight loss method is feasible, you only need to look at: 1. Whether it can help you to exercise actively and improve your heart rate and metabolism. 2. Whether it can help you develop good eating habits and choose healthy food. Whether I can give you the encouragement and support you need in the process of losing weight. 4. Whether the side effects and precautions are clearly explained. 5. Can you stick to it for a long time and become a habit? 6. If you lose more than 1kg every week, you should slow down.
