Two Types of Stomach Vacuums?

In this video I propose that there are two kinds of vacuums, based primarily on the shape of the individual's ribcage.

Examples include: Frank Zane, Arnold Schwarzenegger, Chris Bumstead, Mike Mentzer, Tony Pearson, Jay Cutler, Luke Sandoe, Danny Padilla, Courage Opara, Steve Laureus, Regan Grimes, David Hoffman, Keone Pearson, Bill Pearl, Moses Ashby, Brian Buchanan, Samir Bannout, Wesley Vissers, and Freddy Ortiz.
