So I have seen two types if abs on body builders. The guys with lean, sleek abs with a small waist and the guys with big, blocky abs with a bloated looking waist. I can see the appeal of both styles however I want to train my waist to be defined but still small. I guess the best example would be Arnold Schwarzenegger the guy had the ideal waistline in my opinion. On the other hand Ronnie Coleman has a huge waist and blocky massive abs, not what I am going for.
So what exercises should I avoid and what exercises should I concentrate on to achieve the results I am looking for?
