About the Plank Exercise: The plank exercise is a great way to build endurance in the abdominals as well as the back, and the stabilizer muscles. Building on the core muscles this exercise can prove quite more effective than most other ab exercises in a shorter period of time. Muscles Used in the Plank Exercise: All of your core muscles are used during the plank exercise including: rectus abdominus, transverse abdominals, lower back extensors, and even a slight use of the obliques and abdominals groups.
As in most arm balances, arm strength is something of a factor here but it's really all about core strength. All those deep abdominal muscles are what give you the control to do balancing postures. And doing plank (correctly) is a great way to build them. Next stop, crow pose! To get the most out of plank, you need to use your abs to support your body's midsection, keeping that straight line of energy from the crown of your head to your heels. Increasing your hold time in plank is another good way to build strength.
