“Reverses bulking.” Right. Because all of the girls who will end up reading this probably suffer from “I went to the gym, used the elliptical, did 50 crunches, and suddenly I’m the Hulk” Syndrome and can’t seem to figure out how to make those big muscles go away.
Anyway, if you click through to the source website, you will be told that the key to a getting a “perky butt” is to target your lats, because they crisscross across your back to connect to your glutes. That’s right, apparently targeting your lats will give you a better butt than, you know, doing an exercise that actually targets your butt. Maybe you’re supposed to clench a lot?
