RunnerDude's Weekly Exercise: Planks

I've posted many times on the importance a strong core plays in efficient running and prolonging endurance particularly in long runs. Planks are a great core exercise. They can be done practiclaly anywhere, require no equipment and actually they work more than just the core. There are several variations of the plank, but the best one to start with is the basic front plank.

To do this exercise, lie face down on a mat. Engage your core and lift up on your elbows, forearms, and toes. Make sure your elbows are positioned directly underneath your shoulders. Your body should be a straight line from shoulders to heels. If you're new to planks, try holding this position for 30 seconds. Over time work your way to 45 seconds, and then 60 seconds. Make sure you're breathing evenly while holding the plank position. Do not hold your breath.

For an advanced version of the front plank, try extending your arms so that your elbows are fully locked.
