how to achieve bone hypertrophy

[ripcordgod1]

train facial muscles
muscle tendon will tug on the bone and cause slow damage of the bone
bone must regrow stronger to handle this new force

bone smashing would also work in theory but needs to be done professionally
just using a rock is retarded and will just give you a weird deformed bump on the side of your face, will look more like a tumor
