Your scapula must stay stable and move in sync to lift your arm efficiently.
When it doesn't? It shifts forward, tilts, and your movement loses power.
That’s where two key muscles come in:
🔹 Serratus anterior: keeps the scapula anchored to the rib cage
🔹 Trapezius: pulls it down and controls motion
These muscles don’t just move the scapula; they stabilize it dynamically so your shoulder works as it should.
