After practicing Salman, the stomach gets bigger, which may be caused by the wrong exercise method or the failure to master the correct breathing method. The correct Salman movement should be the state of core tightening and abdominal muscle tightening, flexion and extension, swinging from side to side, rather than twisting with the strength of waist and abdomen. In addition, during the practice, you need to keep breathing smoothly, and don't hold your breath or exert yourself too hard. If the practice method is not correct, it may lead to a bigger stomach. It is suggested to exercise according to the online video tutorial and pay attention to the way of breathing.
