Beginner: Gate Pose can be a challenge for beginners as you test your balance and strength in your arms. Try to push the outside of the top foot into the mat to steady yourself. Keep your abdominals energized and feel very long in the waist. If you lose balance, do not worry, falling is part of the practice.
Advanced: When you are comfortable in Gate Pose, become invested in the full expression of the posture. Focus on your chest stretching and lifting, following the direction of your head. Circle your arm in a fluid, complete motion, and really stretch into the extension. Push your grounding arm down. Are your shoulders away from your ears? Remember to lengthen through the neck and keep the gaze focused on a drishti point for balance.
