In fact, everyone has abdominal muscles. Why can't ordinary people's abdominal muscles show up? That's because there is a layer of oil on my stomach. If you want to build abdominal muscles, you must first lose the oil. Like my roommate, a boy weighs less than 100 Jin. Is he thin? Because of his low body fat rate, you can clearly see the abdominal muscles in his stomach. Therefore, if you want to see the abdominal muscles, you must control the body fat rate at a certain level. If you want to practice abdominal muscles, it is not a single training, but also aerobic and anaerobic cooperation. You can download some fitness apps, such as Go Horizontal and keep, which all have systematic fitness programs. Persistence is the key to training according to the plan. I wish you an early abdominal exercise.
