Planking the right way! Works the arms, the abs, and the spine.
How to do Plank Pose
By Ann Pizer, About.com Guide
Benefits: Strengthens the arms and spine. Preparation for more challenging arm balances.
1. From Downward Facing Dog, draw the torso forward until the shoulders are over the wrists and the whole body is in one straight line. This is very similar to the position you would take if you were about to do a push up.
2. Press the forearms and hands firmly down, do not let your chest sink, press back through the heels.
3. Keep the neck in line with the spine and broaden the shoulder blades.
Beginners: Move back and forth between Down Dog and Plank making sure the distance between your hands and feet does not change.
Advanced: Try lifting one leg at a time.
