Beginner: Dancer Pose is a beautiful pose for the beginner yogi to attempt. This is a great pose to practice along a wall or using a chair for balance. For now, it may be enough to simply raise your leg behind your body! Reach your hand back toward the foot if possible.
Advanced: Advanced yogis can deepen their Dancer Pose by continuing to lift from the chest and also the foot of the raised leg. Shoulders should stay relaxed and low. How does your neck feel? If there is tension or compression in the spine or neck, you may be over-exerting, so consider relaxing a little bit!
