Get a Core of Steel With the Superstrength Plank

Ah, the good old plank. While the core-blasting move packs a serious punch, it tends to feel a bit boring, since it doesn't call for any movement. If you're like us, you'll basically end up spending the entire duration counting down the seconds and thinking about how shaky your arms feel. That's why we're introducing the (drumroll please) superstrength plank. Not only does it add some much-needed kick to the exercise, but it also dials up the obliques workout. Win win.
