What it is

A mountain climber where each knee drives toward the opposite elbow instead of straight forward. The rotation brings the obliques into play while keeping the heart rate up. Hold a solid plank and move the legs quickly without bouncing the hips.

Technique tips

  • Start in a high plank, hands under shoulders
  • Drive each knee toward the opposite elbow
  • Keep the hips low and level
  • Stay light and quick on the toes
