A winged scapula occurs when the shoulder blades float away into the shoulder socket from the spine. It results from the weakness of shoulder blade stabilizers. Serratus Anterior also referred to as the punching muscle is usually the most affected.
The scapula is essentially the base of every movement in your arm and is also the foundation of your shoulders making winged scapula exercises vital. The serratus Anterior holds your shoulder blades against the ribcage. It means the shoulder blade must be mobile and stable. Lack of stability and mobility may lead to scapula winging.
