Indications of the external

People often think that they are using internal power but are still tensing their muscles or just moving their arms.

These are the telltale signs:

1. Pushing when delivering force
    
2. Their arms tremble when you push them
    
3. There is no 'give' (folding) in the joints
    
4. They push back into you rather than employing inherent peng to absorb and channel the force (yielding)
    
5. Wardoff/peng is seen as a stiff barrier rather than a springy 'feeler'
