Hello Coaches. I need some advice. please read this and help me. I would like to get advice on injuries and suffering caused by lunge movements. Some of my players have severe pain in the back of thighs. Thigh in the front foot. I think it's closer to my buttocks than my thighs. I have never felt such pain while doing fencing Doctors are not just inflammation, but more serious problems. Rumor has it that this injury can be solved with more lunge. But I do not believe it. Through this page, I would like to get help from various coaches around the world. Help.
