Which series emphasizes rear deltoid and shoulder blade control?

• A. Series I #4
• B. Series I #7
• C. Series I #5
• D. Series I #6

Answer: (C)

Focusing on rear deltoid engagement and shoulder blade control means training the back of the shoulder and the scapular stabilizers to move together with the arm, rather than letting the front of the shoulder or chest take over. In Series I, the exercises that develop this pattern cue you to pull the shoulder blades together and down, while you engage the rear deltoids as you move the arm. This combination creates solid scapulohumeral control, keeps the shoulder stable, and prevents shrugging or unnecessary tension in the front of the shoulder. So the option that centers on these cues—strengthening the rear deltoid while maintaining correct shoulder blade positioning—is the best fit for this requirement.
