I can attest to picking things up when your young and the problems you get when your older. When I was 24 I picked up a 3 flight 12" rock auger, it was about 4' in length with a 4" solid stem. I dont have any idea what it weighted total, but when I put it down there were stars flashing in my eyes. Now I have a back problem with 4 bulging disks and degenerative disk disease. I say work smarter not harder.
