I have 2 questions: 1. I'm able to endure punches thrown by people, but I still want to better myself. Any advice from the sempais? Btw I'm doing leg raises on a daily basis and bench presses 2 times a week. 2. I've heard that there are Karateka whose blocks are like attacks, which must mean their bones are extremely dense. What exercises do you guys recommend for building this kinda power?
