You Want to Run Faster? Start With Your Core!

This move teaches your abs, back, and hip flexors to all work together to strengthen your center.

• Start on your back with your elbows resting on the floor at 90-degree angles.
• 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.
• Do 10 to 15 reps.
