Lift your legs and tighten your abdomen to train your abdominal muscles

The method of raising your legs and tightening your abdomen is suitable for people who sit at work for a long time: Sit on a chair, straighten your waist, put your hands on both sides of your thighs, and Live on the edge of the chair.

Use your abdominal muscles to slowly raise your knees toward your chest, pause at the highest point, count from one to five, and then slowly lower your knees.

Doing this kind of action six times in a row, then resting for a while and then repeating one set, has a very good effect on eliminating abdominal fat.
