# Cross-Body Shoulder Stretch | FREE 4K Videos | 321 STRONG

> Desk work holds your arms in a fixed forward position for hours, creating chronic tension in the posterior deltoid and rotator cuff muscles that never gets a chance to dissipate. This tightness restricts shoulder mobility and contributes to the shoulder impingement and mouse-arm discomfort that desk workers develop over time. The cross-body stretch directly targets these overworked posterior shoulder muscles.

## この動画について
  Desk work holds your arms in a fixed forward position for hours, creating chronic tension in the posterior deltoid and rotator cuff muscles that never gets a chance to dissipate. This tightness restricts shoulder mobility and contributes to the shoulder impingement and mouse-arm discomfort that desk workers develop over time. The cross-body stretch directly targets these overworked posterior shoulder muscles. 

  
### テクニックの実行方法
    1  Press your palms forward at shoulder height, then bring one arm across your body.

   2  Use your opposite hand to pull the crossing arm closer to your chest, going as deep as comfortable.

   3  Keep your shoulders away from your ears and sit straight and tall.

   4  Take a deep breath and allow the posterior (back) shoulder muscles to expand and release.

   5  Keep pressing your palm outward while you continue pulling the arm in toward your chest with your opposite hand.

   6  Breathe deeply and hold, relaxing your wrist as long as your arm stays extended.

   7  Reverse the stretch on the other side: bring that arm across at shoulder height, pull it in with the opposite hand, and hold.

   8  When done, return out of each stretch in a reverse motion back to your starting position.

    
### 効果
