jokes aside, legs/core are the roots to a tree. they support your entire bodyweight -your arms don't. w/o a stable foundation in which a structure can be built upon, there is a limit to how big that structure can really be.

if you're man enough to carry 100s of pounds over your back, an arm curl will be child's play... nd no this doesn't work the other way around Lol.

I can carry 100s of lbs on my back but can only curl 25's for a meaningful number of reps
