training

hi there,
i've got one question- I'm far away from nearest spot, working, studying. for this moment i cannot surf, but i'd like to stay fit and be prepared to catch a wave again. i train on the concept2- rowing machine. do you think it'll help to stay fit for surfing? has anybody ever tryed it? does it use the same muscles as surfing?
thanks and regards,
