Boys' eight-pack ABS will make girls' eyes all focus on you. From a person's form, it is actually easy to find your self-discipline, and then it is easy to see what kind of person you are. If a boy wants to get the attention of his little sister, I can ask you to develop eight-pack abdominal muscles in several ways, and follow this method.
Jog first 10 minutes. Lie down and do sit-ups. Then get up immediately and make a sprint. Hold on for more than 30 seconds. Then immediately lie down and do sit-ups. Get up and jog for another 3 minutes. Lie down again. Then get up and sprint. In fact, this method is very tiring, and few people can persist in it. It is precisely because they are very tired that once they persist, the effect may be beyond your imagination. It's not a dream to speed up eight-pack ABS in a month. Of course, there is also a premise that you can't be a big fat man. If you want to do this, you have to lose fat first.
Bend sideways? Stand straight. Separate your legs, raise your arms horizontally, bend your upper body forward, extend your left hand to your right foot, raise your right arm naturally, don't bend your legs and arms, inhale, and then exhale. Repeat in the opposite direction, 8 times in a row. This is less violent than the above, and its main key factor is to do all the actions in place. When the intensity comes down, then the actions must be done in place, otherwise it will be futile.
Leg bending exercise? Keep your arms flat on the ground in supine position, lift your knees at the same time after your legs are straightened, inhale to make your thighs close to your abdomen, then exhale and slowly recover. Repeat 8 times. This is similar to the above method, but the action should be in place.
Keep training these movements every day. I promise, your eight-pack ABS are right in front of you.
