Beginners who practice abdominal muscle tearing are puzzled. Why are you more tired than your abdomen after practicing your legs?
The leg muscles of fitness novices are weak, and the abdominal muscle ripper is very different from the ordinary abdomen. Because I want to practice to the lower abdomen. At that time, because of weak legs, the abdominal ripper did not insist on doing it, in order to strengthen the leg strength. It's very easy to be an abdominal muscle lacerator now, and my legs no longer feel sour.
