k if u get bruised doing millz or flarez jus simple take a break and in that break c how bad it is. and if ur impatient and agraid 2 lose wat u learned even thought that rareley happens just do what i did i put some extra padding on my shoulders when i bruised and gave minor cracks in the bone, when i was learning millz. and for padding i dont mean the skatebord guards or that shit jus use some clothes or a cloth and put it under ur jeans or shirt where it hurts and b4 u go serious c if u have enough support there so u still dont get hurt!!!. and if its 2 much and u cant practice be good little kidz and lie down lol

anywayz try it it helped me
so anywayz peace.
