Why do I have three abdominal muscles on my right and only two on my left? I have been exercising for three weeks.

It takes a process for muscles to grow in size and become solid and powerful. You need to practice for a while. What you see is rectus abdominis, which is divided into two parts by the midline of the human body. Each part has five nodes, starting from the sternal stalk and ending at the pubic symphysis at the bottom. After a long period of muscle training, we can see that the muscle has 65,438+00 protrusions, five on the left and five on the right, but the above two are easily absorbed by pectoralis major. It will take another 2-3 months for the muscles on both sides to protrude.
