Jumping with roommates, jumping 1, feeling 1 is the hardest, jumping off is very tired, and thighs and the like will react the next day. There is a certain body shaping effect, because losing weight is exercise after all, and it needs to be done step by step, so you can't seek comfort in the data for quick success and instant benefit. One of our classmates danced for a month (about 30 minutes a day in summer) and lost ten pounds (don't be superstitious about data, others have a large weight base). I really need to have a continuous heartbeat, because I am really tired at first, and I will be paralyzed every time I jump (of course, it depends on how the action is completed. I'm a little perfectionist, so I try to follow the standard and the effect is ok. ) Again, the important thing is to persist! ! !
