The Gym Trainer has worked out his body ever since he could mutter the word "lift". However none of his strength can be used to intimidate anyone as he has never mastered the art of sword fighting. He cannot be bothered to learn sword fighting as that would mean not working out at the Gym. The Gym Trainer's plan is to have other people bring him the knowledge of sword fighting. Bring the Gym Trainer Craft Books so that he can learn sword fighting and be rewarded with Gym Passes, however you will have to teach him fast as he has to get back to lifting.
