"Where is the dividing line between building your body up and wearing it out?" From personal experience: roughly aged 50 (give or take, probably give.) That's without farting around with big weights. 600lbs is about 270 kilos. There is no reason for your body to need to deal with moving weights like that unless you are in a competition or trying to save a life. Hence it is not built for loads of that magnitude on a regular basis. Running with an 80-100 lb pack/load on your back and holding a 20 lb lump is a reasonable load to put on a very fit body, aged up to say, around 40. Your local Army, Marines, etc will know better than me what to encourage here. Try this lot: https://www.paradata.org.uk/unit/infantry-training-centre-catterick https://www.paradata.org.uk/unit/infantry-training-centre-ca... for example. I'll just suggest that for most people, messing with weights like that are simply daft. We are not fork lift trucks. In the rest of the world, 25 kilos is considered a normal one man lift. Humans as a species are designed for endurance, not huge loads.

In what natural scenario would a human be running with 80 extra pounds on their back? That seems like a great way to destroy your knees. > Your local Army, Marines, etc will know better than me what to encourage here Nothing about the military is designed to be long lasting. The system simply isn't worried very much about what happens to the knees and joints of its members. You can't even enlist in the army if you're 35. A friend of mine was in the army - his job was artillery. Even though his hearing was perfect before entering the army, he needs hearing aids now because artillery is loud, and the army simply doesn't care about his hearing. This is an anecdote but I can deadlift 550 lbs, probably 600 if I was going for my 1RM, and I've never really had any joint or back pain in my life. Meanwhile, I have similarly aged coworkers who love running but can't even bend over to pick something up due to their bad back or knees.

  While I don’t do it anymore, in my high school and college years I hunted quite a bit. Depending on the terrain, I would routinely have to pack out 100 to 125 pounds of meat uphill. Wasn’t running (sometimes shuffling if getting dark or starting to rain/snow), but that much weight on the back isn’t out if the norm. Another anecdote - Up until this past year (I’m 43 going on 44), I was routinely pulling about the same weight as you. I peaked at 637.5 (which still wasn’t enough for a good placement in a meet). I never had back pains or joint pains like yourself. For me, even though I had no pain, the next day, after pulling 600, was just miserable. I had no energy, was sluggish, etc. And yes. I ate. When peaking, I was always eating between 3500 and 4000 calories at 195bw. So I’ve not dead lifted heavy in 6 months. The stress on my central nervous system just isn’t worth it anymore. I’ll keep my lift at about 350 for 10 singles. That’s more than enough for me at this point in my life.

  If yo want to run for the long term, I'd suggest barefoot jogging. That'll teach you proper form for protecting your joints very quickly. And human bodies are literally made to jog longish distances barefoot. I also like deadlifts. They are great as well. As a rule of thumb, I guess, any amount of lifting you can do with only investing a few hours a week at most (and no steroids) is probably not enough to destroy your body.
