No problem! Here‘s the information about The shin bones: Shin bone training is a conditioning practice used in martial arts and combat sports where the shins are repeatedly exposed to controlled impact, such as kicking heavy bags, pads, or hard objects, with the goal of gradually desensitizing the nerves, toughening the skin, and stimulating microfracture repair in the bones, which over time makes the shin stronger, less sensitive to pain, and more effective as a striking weapon in fighting. #mm
