Which exercise focuses on scapular mobility?

The focus of scapular mobility is best addressed through seated arm work. This exercise involves movements that require the shoulders to rotate and the scapulae to move properly, promoting flexibility and strength in the muscles surrounding the scapulae. During seated arm work, the arms move in various planes while the torso remains stable, which allows for an emphasis on how the shoulder blades articulate with the ribcage. This is crucial for maintaining shoulder health and improving overall upper body function.

In comparison, kneeling abs primarily target the core muscles and focus less on the movements of the shoulder blades. Pushing up is more about developing strength in the chest, triceps, and shoulders, with limited emphasis on the mobility of the scapulae. The flat back exercise typically emphasizes posture and spinal alignment rather than the dynamic movement of the scapulae. Hence, seated arm work is specifically designed to enhance scapular mobility, making it the correct choice.
