I've been thinking on this... Would a realistic super solider/super hero style character just automatically be a boring read? 90% of the time would be spent to describe how they exercise, do training exercises, manage their diets, and in relation to their personalities generally they would mostly be super professional yes men. But a lot of people seem to like characters like this (Jack Reacher comes to mind). So is this actually interesting, even though it sounds really boring? Or are people really just reading things like this to hear about the punching and kicking?
