* Muscles work best  when they can calibrate  tone
*  Muscles calibrate tone and cultivate awareness through negotiating  resistance
*  When a  muscle has the opportunity to engage with many different degrees of resistance, it learns to adapt and calibrate its level of tone
* Flexibility and strength  are about the relationship between the nervous system and the muscles
* Increasing flexibility and strength  is a process of reeducating the nervous system through conscious attention and practice as much as it is about stretching and repetitions.
