Is that his rib cage or a set of well developed serratus muscles?

LOL! If I wanted to look like Brad Pitt I would stop training and do push ups on occasion. Never would I dare step foot in a squat rack!

Mick Jagger has a LBM of 9 lbs.!


Mr. Antichrist Superstar is quite impressive for a celebrity. His rib cage is hardly visible, he has a 2 pack and his scars can be mistaken for striations!
