That is some serious strength and stamina right there. Unbelievable!

I started watching a bit of the video, and will probably continue to watch it in bite-sized portions. While there is no denying these guys' strength and commitment, do they necessarily have to carry so much fat to move the kind of weight that they do? Serious question. They walk like they're obese because, well, some of them kind of are. And what I saw of one guy's diet thus far, it's not exactly a longevity-enhancing one. Just saying.
