I'm not sure we needed an academic study to tell us that women find men's abs attractive, but here ya go.

Researchers at Western Illinois University just released the results of a study where they observed which muscles women find most attractive on a man. Here are their rankings:

#1 - Abs.

#2 - Biceps.

#3 - Chest.

#4 - Obliques

#5 - Triceps.

#6 - Butt.

Remember, all guys have these body parts, most of us just lack definition. That's all.
