How fun can it be to make hundrends of sit ups everyday for a long period? Yet, strong abdominals might be a must in order to be top in some fields (let's say to be a soccer player in Chelsea) or to be the actor that plays Leonidas in 300. Building strong abdominals IS painful and boring and it takes a lot of motivation to do it.
Not necesarily boring. What if your dream is to become the best body-builder? "Fun" and "boring" are relative. Some consider fun to go out every Saturday to hit a disco, but I don't really like them (way too noisy). On the other hand, I consider programming fun, but there's a lot of guys that think that me coding in my free time is weird.
