Of course, exercise can be done. You can do more left and right overhead movements and some weight-loss exercises aimed at the waist and abdomen, such as Duoyan Zheng weight-loss exercises, but don't be too intense and pay attention to moderation, because you may hurt your spine.
Besides, don't sit for a long time. Also, especially after eating, don't sit down immediately. This is the prime time to hoard waist fat. You can do things standing or walking for more than half an hour.
