Your shoulder is the most mobile joint in the human body.
The glenohumeral joint (ball-and-socket joint) gives you more range of motion than any other joint — allowing you to throw, swim, lift, scratch your back, and reach overhead.
But here’s the catch 👇
Because it prioritises mobility over stability, it relies heavily on the rotator cuff muscles and scapular control to stay strong and pain-free.
More movement = more responsibility.
If those supporting muscles aren’t doing their job, pain often follows.
