Has anyone else watched this show on the Discovery Channel or wherever else you might find it?
I watched it for the first time yesterday, and it's actually a super interesting show. They called up Rampage Jackson and got him to punch a punching bag covered in sensors, and they calculated his punching power to be 1800 pounds of force. They also did super intense sumo, rugby and football hits.
Cliffnotes: watch this show. It's good.
