Looking for beefier biceps? Do more curls, right? That’s the usual prescription. It is also not the fastest way to build big arms. Don’t get me wrong, curls are fine, but if you’re not chinning, you’re not maximizing the strength and size gains of your biceps. Chinups are done with the palms close together and facing towards you.
They are different from pullups, which are done with a wide grip and the palms face away from you.
If pull-ups are part of your program already for back development, you can still do chin-ups. They’re are different enough that you will benefit from both. Here’s a sample back/biceps workout I frequently do:
3-4 sets of sternum pull-ups (pullups done with torso rotation so that the sternum touches the bar)
