There are only so many variations of biceps curls, but we prefer to discover and milk every last one of them. In our November 2012 issue, we gave you a biceps workout that touched on all the basics: standing curls, incline curls, lying curls, and reverse curls to stimulate the forearms. More than four years later, that concept remains largely intact, only with a few minor (yet noticeable) tweaks. This time there will be no lying around.
