Can I tell you it's no use? Maybe my internal organs were damaged. I didn't lose weight, but I suffered internal injuries. Please remember that these auxiliary devices have no claimed efficacy at all. They are also the equipment that you need to control yourself, such as dumbbells, bicycles, barbells, treadmills and so on. These are the choices you need to lose weight. Even if there is no equipment, the weight loss efficiency of jogging 1 hour is godlike at present, and it is difficult for you to get fat.
