I've worked with plenty of former special forces types that were into what I call 'extreme fitness'.
They held mock 'boot-camp' in the company parking lot ... did company tough mudder and warrior dash teams.
You couldn't get me to belly-crawl through an icey & electrified mud pit. No way, Jose'! Not for all the tea in China!!!
but this looks like F U N = FUN!!! (capitol letters because it looks THAT FUN)
Check out some of the videos on YouTube (click the YouTube lookin' icon thingie/link/dinkus)
It's not coming to DFW, but I can do Tulsa!
