Ask any strength or run coach one of their favorite moves for core stability and they’re likely to answer with “planks.” This traditional core exercise targets the abdominal muscles, including those deep in your midsection, like the transverse abdominis, as well as the obliques (on the side of the torso) and the rectus abdominis (those muscles that people refer to as the “six pack”). But it also gets the glutes, quads, shoulders, arms, and back involved in the action. In other words, it’s one total-body exercise.

If you get bored of holding a regular straight-arm or forearm plank, though, there are plenty of ways to switch it up—especially if you want to turn up the challenge. Enter: these two dynamic plank progressions from Runner’s World Other Hearst Subscriptions., Men’s Health fitness director. You’ll find these variations included in the new Runner’s World and Men’s Health collaboration, called 20-Minute Functional Core, in the All Out Studio app, which is included within the Runner’s World+ premium membership.

Before you add these exercises to your routine, it’s important to master a regular, isometric plank first. To nail that, make sure you hit these form points:

  • Shoulders stay right over wrists, and you push the floor away with hands to create space in back
  • Engage glutes and quads to maintain stability
  • You can incorporate these plank progressions into any
  • Best Folding Treadmills
  • Don’t let hips dip down or pike up
