What is said upstairs is very good, you can think about it! That's how I lost weight myself. Skipping rope and plastic wrap are not needed. It's only been a month, about 20 days. I lost 6 Jin. I seldom exercise, so the effect of skipping rope is very obvious, but it is really painful to stick to it! I almost forgot to tell you that you have to jump at least 1600 times a day! Stick to it, this is the most economical way to lose weight!
