Mass rises as the cube of size, but muscle power rises as the square of 
size. (This is why ants can lift 1,000 times their own weight, but 
elephants can only lumber along.)

Besides, you can move on all fours with your elbows locked. That doesn't 
take much muscle power. ;-)

A door isn't nearly as heavy as a person.

I did, however, move a piano up a spiral staircase one time... Jesus, 
THAT was fun! o_O
