Pull-Up Strength: The Missing Link
One of the most impressive displays of strength-to-bodyweight—not to mention one of the best ways to add muscle to your upper body—is the pull-up. (If you don't find it impressive, think about it for a minute: you're using your upper body to pull your entire body up your entire arm length. I mean, holy shit.)
Thing is, unless you're one of the guys who can jump up to the bar and bang out 12 good ones right now, it's safe to bet that one of the biggest muscles in your body is probably one of the weakest, too. And that's never a good thing.
