I have been a fitness instructor for 8 years. First of all, I tell you that abdominal muscles are the most difficult part of the human body to practice. Because abdominal muscles participate in every movement in daily life, its anti-fatigue degree is much higher than that of other parts of the body. It is the most scientific to practice five times a week, because muscle tissue needs more repair after exercise to form.

Let me remind you that it is better to divide the abdominal muscles into three parts: the upper abdomen and the lower abdomen. Divide your plan into four groups with an interval of 60-90 seconds, which is a scientific exercise method.

The main actions are sit-ups, leg bending, sit-ups, kneeling posture, stretcher, abdominal posture, knee bending, leg lifting, leg lifting and so on.

The exercise of bilateral muscles is to add a twist to the exercise of anterior abdominal muscles. For example, it is enough to add a left-right twist while lifting your legs or bending your legs to sit-ups.

Finally, there is a detail to tell you. Are you from the north? If yes, is your subcutaneous fat thick? If it is thick, it will also affect the outline of your abdominal muscles. Come on! Try hard, but pay attention to details!
