I was watching the NBC show American Ninja Monday night and was surprised at how light weight these guys were, but still looked muscular. One guy was 5'11" and weighed just 145 lbs. Another guy was 6'5", 180 lbs. They go through an obstacle course and most of the skill involves grip strength. I didn't hear the details on the prize money, but it was either $1 million total prize money or the winner gets 1 million. These guys are so serious that they even build replicas of the course in their back yard or at their farm. The finals are coming up.
