The military crawl? You can do it on your hands and knees. The obstacle is NOT that low. Even the barbed wire in the mud pit is high enough you can do all fours.

The climbing stuff is all about legs. Your arms/hands are just for holding on once your legs have lifted you, not for pulling you up.

MD’s WD didn’t even have the cars last year, even though they put it on the website. I think they just randomly throw up a list of obstacles on each page–what you see is not necessarily what you get. Um, maybe that’s not helping.

All that said, even finding 15-20 min 3-4 days/week will help your arms. My coworker who’s organizing our work team sends out weekly digests with training suggestions–I can forward them to you!
