No, I separated my rectus abdominis after delivery, so I bought this machine. My elder sister is fat and wants to use it for a long time, so I consulted customer service. Can I lose weight? The customer service feedback said yes, and then instructed my sister to use it for a while. Her body fat was obviously reduced, and a reagent was given to test whether it was reduced. She chooses slimming and shaping mode every day to induce muscle movement or simulate normal voluntary movement, and the effect is also very good.
