Pavlov stipulated two types : Strong and Weak.

One socionist (don't remember his name) said Weak types were IP types, and Strong types all others.

More accurately :

  • EJ is Strong, Balanced, and Mobile.
  • IJ is Strong, Balanced, and Inert.
  • EP is Strong and Non-balanced.
  • IP is Weak.


But how are Strong types strong, and Weak types weak ? Is there a difference in conditioning practice between Strong and Weak types ?
