Add This Core-Crushing Plank Variation To Your Next Abs Workout

“We’re going to take the static movement of a plank and add a dynamic aspect to really kick it up a notch,” Martino says.

So, what is that notch, exactly?

Basically, the plank is a static exercise—that is, technically, you’re not moving; but you’re still working hard to stabilize your body. Anyone who’s done a plank knows that, while simple, holding this position with proper form is anything but a walk in the park.

When you add movement to the equation, your body has to work even harder to stabilize itself, because you’re now fighting against not only gravity but also the momentum generated by whatever dynamic element you’ve added.

In the case of the dumbbell plank pull-through, that dynamic element comes in the form of dragging a dumbbell back and forth from one side of your body to the other.

As Martino points out in the video above, the key to getting the most out of this exercise is keeping your core and hips as still as possible as you move the dumbbell.

“Notice, guys, there is no twisting whatsoever at the midline,” Martino says. “Everything is staying super, super tight.”

Watch the video above for Martino’s directions for pulling off this move with proper form. Then, try it in your next workout, going for three sets of 20 pull-throughs—10 on each side.
