Fun Shoulder Video

After my post on hip mobility, I had a question about shoulder mobility. So instead of writing a post with pics, I had my poor wife record a video late at night (thus the orange glasses again).

Here's the recap:

  • your humerus (arm bone) can move up to 1" out of the glenoid cavity during normal range of motion
  • shoulder stability relies on glenoid labrum, joint synovium and muscles/ligaments/tendons/bursae/capsules
  • shoulder held in place by the four muscles of rotator cuff and pec muscles
  • in order to drive synovial fluid into all connective tissues you have to get your shoulder joint moving in all directions that it should -- and it's the joint with the highest range of motion of any joint
  • I give some examples of mobility work you can do

Enjoy!
