1. Active shoulders / Engaged Shoulder Girdle
   Flex pecs or shoulders up, back, down.

2. Smooth Movement
   No jerky or janky movements.

3. Strength and Stability
   Not just the shoulders about all the supporting muscles.

4. Sound Positions
   A strong, stable shoulder is not strong and stable when in a bad position.

5. Flexibility and Mobility
   When you are able to use full ROM the shoulder is more resilient.
