You must be quite the lucid dreamer.
It's not like this course is all these guys train for. This is supplementary to what their real goals are. Notice the guy isn't exactly the picture of physical perfection? This is NOT the hardest thing these guys do. Not even by a long shot.
I'm pretty sure TONS of mid-top level CrossFit people could do this, not to mention any gymnast that is worth their salt. I can peg 4-5 people, not including myself, in my local gym that could go out and do that, and we would be excited to. It looks like a fitness hobbyist's playground to me. Any real athlete can knock this thing out in their first few tries, if not their first (meaning no errors).
I'm pretty honest about my fitness levels.
So I outed myself as a fitness enthusiast who is confident in himself. You outed yourself as a dude who likes to go to gyms and hang out around the smith machine. It's OK dude.
