Jareth took a firm stance, arched his knees a little bit low, back erect and his head steady. He maintained that posture for a minute, allowing Astrid take it all in, before standing straight again.
"Now you try," he watched as Astrid tried mimicking him but failed once more.
Jareth sighed, shook his before continuing, "Stand with your feet shoulder width apart, then turn so that one foot preferably your right, is facing forward, with the other between 45 to 90 degrees off."
She assumed the posture according to his instructions, but her back still lacked something.
"Your back should be erect, with your weight balanced between your feet, and your body dropped slightly so that when you advance or retreat your head should remain steady and not bob up and down as you move."
Trying again, she got it almost right this time. He slightly nodded and walked up to her, he held her shoulder with one hand, the other hand on her belly and helped her straighten her back.
