As I see it, the trade itself will make you maintain a certain minimal level of fitness. OK, I'm in no shape for the Olympics- and, if you said I had a "body like a god" you'ld have to be thinking of Budda! Nonetheless, with attic crawls, ladder climbs, pipe caries, and occasional shovel work, one can't get completely out of condition!
The new guys get a lot of "grunt work." This work will certainly build them up to the necessary fitness level.
