Planking is a simple yet effective procedure.

When performing a Plank:

1/ You must always lay face down, ensuring your face remains expressionless for the duration of the Plank.

2/ Your legs must remain straight, and together with toes pointed.

3/ Your arms must be placed by your side, held straight and fingers pointed.

4/ You must make it known that you are Planking. Saying 'I am Planking' will usually get this across. Sternly announcing it will ensure a good result.

5/ Your safety should always be considered. Properly thought through Planking procedures should always go to plan. Never put your self at undue risk.

6/ Every Plank that is captured must be named.

The act of placing ones body in such a way in which arms are by the plankers side & all limbs are at full extension often performed on a unanimous object. The object in which the planker chooses to plank on is entirely the plankers choice, although the more unique the object often the better the plank. The planker usually immortalize the plank with a picture.
