Spiderman plank

How to

Start in a traditional plank position with your forearms on the ground and your body perfectly straight.

Bring your right knee forward towards your right elbow, then return to the plank position.

Repeat by bringing your left knee toward your left elbow.

Alternate sides for a total of 10 or 20 depending on your level.
