Most bodybuilders in the golden age can show their bellies in a vacuum. With the neglect of vacuum abdominal muscles in modern bodybuilding, many people may not know about vacuum abdominal muscles. Vacuum abdominal muscles make the abdomen collapse by contracting abdominal muscles, and bodybuilders can show perfect proportion in the state of vacuum abdominal muscles. It was the most popular in Schwarzenegger's period, because the judges of bodybuilding competitions in that period valued the overall proportion of bodybuilders most, and vacuum abdominal muscles could perfectly present the overall proportion of bodybuilders.
In modern bodybuilding competitions, bodybuilders pay more attention to exercising abdominal muscles in daily exercise. In popular aesthetics, abdominal muscles also conform to most people's aesthetics. It is worth noting that the number and arrangement of abdominal muscles are influenced by innate genes. No matter how you exercise, you can't change the number and arrangement of abdominal muscles, only increase the thickness of abdominal muscles. Many people are very keen on beautiful muscle lines, so many fitness coaches also tend to exercise students' abdominal muscles in the fitness craze. Under the influence of the trend of the times, bodybuilders gradually gave up the once popular vacuum abdominal muscles and began to practice abdominal muscles. This is just like the fashion clothes of each era are different, and the pursuit of muscle beauty in fitness is different in each era.
It should be noted that vacuum abdominal muscles can not only be owned by fitness, but also by a thin enough person. Abdominal muscles are different. If you want to have abdominal muscles, you must pass the acquired fitness exercise. In fact, no matter what kind of bodybuilding effect, as long as it suits your physical condition, that is the best. Sometimes you don't have to follow the fashion trend, just like yourself.
