Does qigong really exist? I want to practice it, my fear is that it doesn't exist and then I'll waste another couple years of my life.

Practicing qigong? If you don't have the perseverance to do it, you should forget about it. It takes years or even a decade to build the foundation for this stuff, and it's easy to hurt your body if you don't practice correctly (it's unlikely that you'll go mad, but I'm afraid you'll damage your internal organs). It's not as simple as a herniated disk to stop when you're swinging a hammer.) Now the real, pure qigong masters are almost none, really understand qigong people are generally martial arts masters, and which more combat school.

The reputation of qigong was lost by the qigong fever of the 1980s, when all the street styles dared to call themselves qigong masters, and in fact, many of the so-called qigong is actually a slowed down square dance, which is useless and also delays time. Wheels also came up at that time, and then there were people who used the opportunity to hype "qigong practice can develop superpowers" and other gimmicks (some of the cities where this kind of fake qigong is more popular are about to be blown up by them into the city of academy). Under the influence of these cowards, many people now think that qigong is fake. But I must say that it is in fact real, only far less fantastical than the propaganda and the martial arts novels of the past. When the real qigong is running, you will only feel a kind of "energy" running in your body, and your consciousness will enter a half-asleep, half-awake state, and after a certain degree, your senses will become sharper, but this needs to be practiced together with the martial arts, otherwise you will not be concerned even if you notice some small movements that you could not notice before! This is my personal experience. This is my personal experience

Those who say qigong is pseudoscience are themselves superstitious pseudoscience. Just because something is not understood doesn't mean it doesn't exist. Gravitational waves can't be understood by ordinary people yet, but can we say it doesn't exist? And for those who say that qigong masters have been beaten up, can I ask those guys to aim their farts at the toilet before they fart, so that they don't fall in the wrong place? Qigong is not meant to strengthen the ability to resist blows, the increase in physical strength is just an additional effect, those so-called chest breaking boulders or legs breaking stakes, either fake qigong, or speed molding hard qigong (in fact, the so-called hard qigong is the external practice of kung fu, must be combined with the fighting techniques in order to play a role). The true sense of internal qigong (qigong in the narrow sense) is to nourish one's health. This kind of stuff simply can't come down without decades. I would suggest that you are better off meditating and meditating, which is kind of introductory and easier for something like qigong.
