I'm intrigued as to what those things are that Brock Lesnar's team are using on the first episode of Ultimate fighter 13. Does anyone know what they are called and what they are for? They hold the devise with both hands and rotate their hands around in a motion similar to hitting a speed ball really quickly. It's a hand held device a little bigger than an Ivanko super gripper.
