Get Your Cardio in and Strengthen Your Abs With the 2-For-1 Mountain Climber

Dominique Michelle Astorino

The mountain climber is a classic ab exercise, and we love it because it will strengthen your core as you simultaneously work on your cardio and muscular endurance. This move is a great addition to any ab workout, especially if you've already mastered the basics like crunches and planks.

How to Do Mountain Climbers

  • Start in a traditional plank with your shoulders directly over your hands and wrists. Be sure to keep your back flat and your butt down, maintaining a neutral spine.

  • Engage your core (think about pulling your belly button toward your spine) and lift up your right knee, bringing it toward your elbow. It's OK if you can't bring the knee all the way to your elbow. Return the right knee back to the starting position as you simultaneously drive your left knee up toward your left elbow. Return to the starting position.

  • Continue switching legs and begin to pick up the pace until it feels like you're "running" in place in a plank position.

  • Continue "running" in your plank for 30 seconds. Repeat for a total of four rounds.
