Guy Tries to Walk On His Hands On a Treadmill, Accident, Video. Yeah this was not smart at all. This was downright stupid. He had the treadmill going fast. He goes in for the stunt like he really thinks it is going to work. He immediately fails/falls. At no point was this close to a success. He face plants on the treadmill. The weight of his body actually flips him forward from the face plant. This one hurt to watch.
