Stanford University Communications teacher Matt Abrahams suggests to help you keep a stable position onstage you:
- Put your feet directly below your shoulders
- Keep your feet parallel to each other (not splayed out on either side)
- Keep your feet side by side (each foot is lined up so the toes and heels are lined up at the front and back)
- Rise up on to your tip toes and then come down again
