Hi, I'm Audrey Laurelton, owner of Equilibrium Pilates in Montclair, NJ. I'm here for About.com today to show you a modified Pilates plank.It's an excellent exercise for anyone who needs to develop their abdominal strength or has wrist and elbow issues and can't complete the full plank pose. To begin, we are going to stretch out and place our forearms on the mat, making sure the elbows are directly underneath the shoulders. Then slide the legs out. Keeping the legs together, you are going to draw the navel up towards the spine, keeping the neck long and you are gong to hold the pose for 30 seconds. If you would like to do a more advanced variation, you are going to separate the legs and curl the toes, lifting up into a nice, full, modified plank Pilates pose. Make sure you draw your navel up into your spine and you never feel any pressure in your lower back. Try to hold for 30 seconds. It's okay if you need to start in 15 second increments.Thank you for watching and for more information, go to: health.about.com.
