Seems even when really lean with noticeable abs I don't have strong definition in this area. Anatomical difference or do I need to do hip shit or what?
The iliac furrow, also known as an athlete's girdle, Apollo's Belt or an Adonis belt, is a term for a part of the human anatomy. It refers to either one of two shallow grooves of the surface anatomy of the human abdomen running from the iliac crest (hip bone) to the pubis. In some circles, it is colloquially referred to as the devil's shoulders.
