Never seen it, just wanted to mention the "henched" guys who came to the gym I trained at could never keep up with the smaller guys on the ANW obstacles. Its not that one is easier than the other, they just require a different set of skills and strengths (and strength to weight ratios).
Also, the first couple seasons may have been more available to "everyman", but these days the initial qualifiers can be as challenging as the semi-finals once were many years ago. What you don't see on the show is the 100s of people who try out after years of training and don't make it. They choose how many successes and failures they show, like any "reality" show the appearance is sculpted
Still, playing at the ANW gym was some of the most fun I've had post-highschool, and I highly recommend it if you can get your gym to do it !
