I was hiking in Nepal a couple years ago. I regularly saw porters carrying 85kg (187 lbs) of wood on there backs up the mountain trails (pic I took: https://imgur.com/a/ahJhoi9). I asked my Nepali guide how much he can carry, and he said "I can carry you!" I'm 195cm (6'5"), and weighed about 120kg (264 lbs) at the time, and this guy was maybe half my size. I told him to prove it, so he asked me to get on his back, which I did, and then he picked me up and started running. Crazy strong.
