What's that hand spinning tool off TUF?

[AdamJackson]

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.

I just found a picture

I think it's called a burn machine. I had trouble finding it, but I just found it then.

Yeah, it's the Speed Bag Burn Machine. I own one and wrote a quick review on it a while back: (External link) Ultimate Burn Machine Speed Bag

It's a fun tool to have laying around and to play with, but there's for more plausible exercises out there that get a better bang out of your buck.
