Old-time strongman (5)
I believe the answer is:
atlas
'old-time strongman' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for atlas that I've seen before include "Set of charts" , "Titan compelled by Zeus to support the sky" , "I carry a huge weight" , "travel book" , "collection of charts" .)
