As a former grunt who got paid to run with rucks... I’m paying for it now. I’m 34 with two bulged cervical discs and some jacked up lumbar discs... the things I’d have done differently 10 years ago, right? Point is, don’t do dumb sh..er, stuff, just because you’re bored or you want to ramp it up. You’ll hurt yourself. I was in peak athletic performance then, and after a lot of hard work, I’m coming back around, running a ton and getting weights in when I can. The stadium drills mentioned here are pretty legit in the absence of hills, and honestly translated well to the mountains overseas... fwiw. But as always, YMMV
