New starters

A new starter is always 'external'.
They use what they bring to class with them:
  1. Aggression
  2. Locked joints
  3. Force against force
  4. Over-contracted muscles
  5. Using the arms independently of the body
These habits are of no use in a tai chi class. They represent a major impediment to progress.

Unlearning is necessary.
'Internal' principles of body use are introduced, explained and explored from the very first lesson, but these will take a long time to become habit.
Daily home practice will significantly speed up the process of change.
