Learn the Triangle Pose - or Trikonasana - in the latest video in our Foundations of Yoga series! Here Adriene breaks down the single posture from the foundation - the ground up- working with action and alignment. This is great for beginners, great for those interested in attending public classes and even great for experienced yogis who want to deepen their practice and invest in a more mindful active practice. Extended Triangle Pose is great for the whole body and can relieve stress in the system. It strengthens the legs and back and is a great pose to radiate from your center and strengthen your core.
