People have eight abdominal muscles, four on each side. Those who practice bodybuilding well can see 8 or 10, while the average person can only see 4-6. But as the above professionals said, there is only one piece. People who practice well have gullies, which seem to be divided into n pieces. People who don't pay attention to sports may be a whole block!

The rectus abdominis starts from the pubic crest and ends in front of the xiphoid process and the 5th to 7th costal cartilage. This is a whole muscle. It is divided into several muscle abdomens by 3~4 tendons. There are eight people and four tendons. Three muscles and six people are related to heredity, but whether it is 8 fast or 6 abdominal muscles, it has no effect on abdominal muscle function.

Ps: The tendon stroke mentioned above is actually a tendon, which is a hard connective tissue ... which is commonly called tendon. Beef tendon is beef tendon. It's not the "tendon" of the "blue tendon", this "tendon" refers to a vein. Pss: Tendon is a cable-like or membrane-like dense connective tissue at both ends of abdominal muscle, which is convenient for muscle attachment and fixation.

Muscle tendons are attached to two or more different bones, and it is precisely because of the traction of tendons that muscle contraction can drive the movement of different bones. Each skeletal muscle is divided into two parts: muscle abdomen and tendon. The muscle belly is composed of muscle fibers, which are soft and contractile in red, while the tendon is composed of dense connective tissue, which is hard and contractile in white. This thing, called tendon stroke, is natural and will not become more or less in your exercise.
