Most muscle men take pictures because of narcissism. Actually, it is not. There are many narcissists, even if you are a little bear, you still have the right to narcissism. The reason why most muscle men practice shooting every day is to compare the changes before and after to see if there are any incongruities, but which one is good. Of course, I also encourage myself from another side to build a heartfelt self-confidence, and this self-confidence is the courage to continue practicing.
