A funny look at the "latest in MMA technology". Coach Marc Montoya from Factory X in Denver, CO put together this training tool using a tennis ball, elastic band and elastic string. He named it the Skull Blaster. Try it out at home and let us know what you think!
Kostya tszyu talked about doin this as a training tool in a vid a few months back.
