Runner's Crunch

  • Start on your back with your elbows resting on the floor at a 90-degree angle.
  • With your core engaged, roll up to almost sitting while bringing your right knee up to meet your left elbow. It should feel a little like running.
  • With control, straighten your leg as your slowly peel your back down, vertebra by vertebra, until your shoulders touch the mat last.
  • Alternate with your other leg to complete one rep.
