For Newbies and Veteran Yogis Alike: Essential Yoga Poses

Sanskrit Name: Navasana
English Translation: Boat Pose

• Begin sitting on your mat. Bend your knees and lift your feet off the floor, balancing on your tush. Keep the spine long and straighten the legs as much as you can without rounding the back. If this is too hard, keep the knees bent — you're still working your core.
• Hold for five complete breaths.

In Ashtanga Yoga, Boat Pose is traditionally repeated five times, with lifts in between each one to really work your abs. Find out how to do the lift here.
