How to Do Mountain Climbers

  1. Get into the plank position with your hands about shoulder-width apart, back flat, and core engaged.
  2. Pull your right knee into the chest as far as you can.
  3. Switch legs, pulling one knee out and bringing the other knee in.
  4. Keep your hips down and run the knees in and out as far and as fast as you can. 
  5. Repeat for desired reps.


Mountain climbers are great for building core strength and agility, as well as some cardio endurance. You work several different muscle groups with mountain climbers—focusing on your core.
