You Want to Run Faster? Start With Your Core!

Adding some arm motion to your planks is great stability training and translates directly to your running form.

• Start in an elbow plank with your palms facing inward.
• With your abs pulled toward your spine, reach your left arm forward, keeping your torso as still as possible. Bring your elbow back to the mat. This completes one rep.
• Repeat on the other side, and continue alternating sides for 20 reps total.
