Doing so Castiel grabs the thrown weights and places them around both of his ankles, as he puts them on his sensei activates the weights which increases their...weight by 10x fold. So with that Castiel struggles to get back up as he bent over to place them, and once he is up he tries to move forward by moving his left leg, he has a large amount of trouble since how heavy they are, but manages to do so, he repeats the process until he can somewhat walk normally around.
They are heavy, but I'll get use to them in a quick fashion.
