Come to think of it, Markus Ruhl doesn't do it either, nor Craig Titus, nor Jay Cutler, nor Kevin Levrone, nor Lee Haney, nor Dorian Yates, nor Nasser el Sonbaty, nor Dennis James etc.
Both Lee Priest and Shawn Ray does it though. As a pump exercise, 5th outta 5 exercises for chest.
Hell, maybe it isn't underrated, maybe it's OVERrated, since pretty much no professional bodybuilder does it, there must be a reason for it.
