Is the shape of abdominal muscles natural?

The font is very vague. It should be said that there are both congenital factors and acquired factors.

The size of abdominal muscles is determined by the tendon stroke. Tendon stroke can be understood as the appearance of white tendons on the muscle surface. If rectus abdominis is a bundle of chopsticks, it is a rubber band tied to the outside of chopsticks. Everyone's tendon is divided into different fabrics, and the number of muscle blocks is innate. 6 yuan is the most common one, and 8 yuan is rare. This cannot be changed.

But we can see that the shape of abdominal muscles depends on the size of muscles and the thickness of subcutaneous fat. These factors can be changed through acquired training.

Even if you have eight abdominal muscles, if the subcutaneous fat is thick, it still looks like a ball. For healthy men, the shape of abdominal muscles can be seen when the sebum rate is below 12. You can tell without training.
