Of course, it is beneficial to lose weight, and the effect is obvious, but you must exercise for 30 minutes to lose weight. Less than 30 minutes is exercise, and there is no slimming effect. If it is a little hard to jump for 30 minutes at a time, it can be divided into 10 minutes for three times. I'm afraid of rubbing my hands or hitting my long leg muscles with a massage hammer after jumping the rope. I hope it helps you.
