Coach Wang Zhi talked about the four elements of bodybuilding: scientific training, reasonable nutrition, positive recovery and healthy psychology, which are the four elements of bodybuilding success. Don't simply think that the muscle has dropped, as the saying goes, "sores (muscles) hurt, but numbness doesn't practice." I suggest you go to Qujiang No.6 Community Fitness Club to talk to Coach Wang Zhi when you have time, or you can get relevant study materials from Coach Wang Zhi.
