This is a briliant preparatory pose for Warrior 3, beautifully shown here by Dani.
From standing in Mountain with hands at heart centre step back with your right leg creating a deep lunge. Inhale the arms to lift up alongside your ears. Allow the right leg to strengthen by pushing the back of your knee towards the ceiling. Weight is over the front leg.
Hold here for at least 5 deep breaths, recognising the resilience you have.
Step back to Mountain. Repeat on the other side.
Next time you practise Warrior 3 you will find it super easy and your leg will float to the sky!
