Hello, if you can reach the weight of 20 kg to 30 kg that you want to lose weight, the price is very cheap, but it is not reliable for me to lose weight for many years, because losing weight is not only exercise, but also food is very important, so it is not feasible to combine it, such as eating less and more meals, not eating too much at a time, or eating too much at a time. If you are a personal trainer in the gym, you look unreliable, because many of them are cheating money. Hope to adopt, remember that weight loss should be combined with body and mind, and persistence will win the rate.
