Hi,
I understand that it has no net mechanical advantage and may have
notable disadvantages.
But my problem is no arm strength. So even if it takes me more
strength to push such a folded pole, I might be able to accomplish it
because the rest of me isn't strength-deprived as my arms are. I
could, for example, use my body weight to help push the pole
frontwards ...
