Well, it's the triceps that have the insertion on the olecranon process, and
if the olecranon is that big, then they've got pretty powerful arm extender
muscles.  Which means that they could send dirt back between their legs just
by flexing that muscle with their arms held normally under their body.  Know
what I mean?
