The rigid fork probably did its part...
I find that riding my SS HT (suspension fork) works my shoulders, arms and back much more than a "gearie" bike. I get more of a full body workout (although I ride for fun, I realise that it must have some effect on my physical condition too
).
The rigid fork obviously makes you feel the bumps more. There's more need to pick lines and remain relaxed but not slack on the bike.
