Abdominal muscle exercise method: 1. 50 sit-ups, two groups, 3 minutes apart. Ask the elbow to be outward, and get up quickly after holding your head.
Push with your abdomen.
2. Your legs are suspended. Bend your legs first, and your knees touch your chest. After you get used to it, lift your legs and straighten them.
As for subcutaneous fat, it belongs to the category of weight loss. If you want to lose fat, you need to increase aerobic exercise. By then, the abdominal muscles will look obvious!
Remember: insist! Perseverance is effective!
This is my personal plan, I hope it will help you. Wish you success!
