The 30-Day Plank Challenge

A strong, stable core is the foundation you need to not only prevent injury but move freely and strongly in every workout. Join the 30-day plank challenge and you'll see noticeable changes in just a month's time.

How To Plank

1. Place elbows directly beneath your shoulders, legs extended.

2. Press through your heels so calves are lengthened.

3. Relax your hand and look at the floor.

4. Keep your body in a straight line.
