When most guys first arrive in the gym, they have one goal in mind: a six-pack. And that's fine. But take a look at the more experienced men moving the heavy iron, and you'll notice they've all turned their attention to the muscles they can't normally see in the mirror—their back. Building an powerful, wide back is crucial to your overall aesthetic. Not only is a wide back imposing in and of itself, but it also makes your waist look smaller, increasing the ever important 'V' look all bodybuilders seek.
On your next back day, add in these four exercises. Pretty soon, you'll be able to see your back in the mirror without having to turn around—that's how big your lats will be.
