The back. It's a muscle group that, when adequately beefed up, can make a skinny guy look as brawny as your gym's resident bodybuilder. Add a stack of back muscle onto a guy who's already bulky, and he's going to look like a total monster.

But, for some guys, the standard "back day" workouts just don't do the trick when it comes to gaining mass. That's where this five-move, unconventional circuit comes in.

Personal trainer, physique competitor, and HUMANFITPROJECT contributor Joey Frad pieced this routine together to help you build the mass you've been working toward.
