My friend's aerobics teacher taught them a set of movements to reduce abdomen and waist. It feels good. But how to do it is really hard to say. It seems that there are four parts. First do twenty sit-ups and straight backs, slow down and fully stretch, then twist your waist left and right, just one or two four or eight beats, and finally push your elbows and legs on the bed and kick your legs in the air for one minute like riding a bicycle. The third one can't remember how to do it. You don't have to do it every day, just do it once every two or three days. By the way, if the waist and abdomen muscles feel sore after doing it, it proves that this is still suitable for you. . Then you have to stick to it

Ha ha. . If you just sit, you will accumulate fat. . . You still have to move, but if you want to sit, you have to twist your waist more. . Theoretically, sitting can only move sideways and twist. . Unless it's an instrument.
