I pulled a few tensioners, and just started doing the first push-up, I felt super pain in my chest, and I couldn't do it anymore. I feel a tearing feeling. What happened?
Hello. You may seldom exercise, and suddenly your muscles are exercised. This is called muscle fiber tear. Eating more things with high protein content is helpful for muscle fiber reorganization, and ensuring muscle fiber tearing every exercise can obviously increase the lines. Your muscles will turn red after a long time.
