  2. Open arms out to sides in wide arc, pulling shoulder blades together.
  3. Form T shape with arms level to body and chest toward anchor.
  4. Pause and squeeze rear deltoids and upper back.
  5. Slowly reverse motion, bringing arms forward under control.
  6. Return to starting position without sagging.
