Queen Bee
I was advised not to, if used wrongly they can push the back out of line or can even weaken muscles because they rely on the support. Apparently, I have no idea if it's true.JLumbar support while beekeeping?
Instead of moving full boxes, have handy another box and move the frames into that as you inspect them, or until you can pick up the box without risking injuring your back.
That's what I do. If I need to move a brood box I shift the frames of stores into another box and move them on their own. Temporarily fill the gap with frames of foundation if the hive has to be moved a long way, don't bother if it's only a couple of feet.
