Under normal circumstances, normal people can see the effect of exercising abdominal muscles by insisting on exercising abdominal muscles for about 3 months. However, because everyone's physique or other actual conditions are different, the time spent will be different. For example, people with less abdominal fat can exercise abdominal muscles directly with abdominal wheels, while people with more abdominal fat need to subtract fat before they can exercise abdominal muscles, so it takes a long time.
The time mentioned above is only an approximate time in an ideal situation. However, the abdominal muscle movement itself is restricted by many factors, so there is no specific time. It's just that you can distinguish who is easier to practice abdominal muscles according to your physique. If you practice more abdominal muscles and spend more effort, the method will be more effective.
