If you really want to develop abdominal muscles, vest line, a4 waist and peach buttocks, I can teach you to practice quickly.
The first movement. Plane, this exercise is to prepare a mat for practice first, buy a mat with buttons as much as possible, then put your legs straight into the buttons, fasten your legs, then exert pressure on your abdomen to make your upper body instantly rise, and then go down and practice again and again.
The second exercise, push-ups, one day 150. The body is facing the practice mat, and both hands are supported on the practice mat. Then, your abdomen and hands are hard, your hands are bent and your body is down. Don't touch the ground, stay for two seconds, then get up and practice again and again.
Third exercise, sit-ups? 200 a day? . Straighten your legs into the buckle belt, hold the back of your head with your hands, and exert force on your abdomen, abdomen and waist at the same time, get up instantly, go down again and practice repeatedly.
The fourth action is butt bump, one day 100. The body lies on the practice mat, the feet are arched, and the hips and lower abdomen are shaking back and forth, so you can practice repeatedly.
The fifth sport, m goula? 80 a day. The legs form an M-shape on the practice mat, and the abdomen and abdomen exert force. Slowly let your body fall backwards, gently land and wait for five seconds, then slowly get up, do it as one, and practice again and again.
Practice according to this method every day, provided that you can't be lazy, practice or fail. As long as you keep teaching you, you will soon have four or eight abdominal muscles. If you think this exercise I mentioned is difficult to complete, you can reduce the number of times appropriately, but you won't build your abdominal muscles so quickly.
