I'm guessing that its mainly the legs which are load bearing in a kayak, not the arms (except in high winds) and not the spine (except when lifting the kayak). Certainly its my legs whch feel stiffest after a days paddling. last year George Dyson wrote and article for Scientific American about native Aleut adaptation to specialized kayaking skills. In it there was a picture of an upper arm bone from a ancient archeological site showing the mass and thickness compared to a modern Aleut upper arm bone. The implication was that repeated daily padding developed bone mass in the arms. This seems consistent with what little I've read about bone mass build-up. It appears the mass build-up occurs on the bones that are loaded directly (reportedly caused by a die-electric effect in the calcium crystals). If your legs are sore it could be from lack of movement, rather than loading. If it were me, then I would specifically exercise the arms and back, preferably in a way that approximates the way the arm muscles are loaded during paddling (rowing machine perhaps?).
