Mountain Climber

  • Start in a high plank — shoulders over hands and weight on just your toes.
  • With your core engaged, bring your right knee forward under your chest, with your toes just off the ground. Return to plank. Switch legs, bringing your left knee forward.
  • Keep switching legs and begin to pick up the pace until it feels a little like running in place in a plank position.
  • Continue alternating for 30 seconds, then rest for 10 seconds.
