Which series focuses on elbow opening out?

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

Answer: (B)

Elbow opening out is about allowing the elbow to move away from the body so the shoulder can rotate and the arm tracks safely along the reformer. This cue helps keep the chest open, the shoulder blade stabilized, and the movement driven from the shoulder girdle rather than collapsing inward at the elbow or ribcage.

The exercise in this series that centers on that outward elbow opening guides the arms to glide with the elbows turning away from the midline as you lengthen or press. That alignment promotes proper scapular control and a spacious shoulder joint, which is essential for safe, efficient arm work on the reformer and sets a solid foundation for more advanced movements.

Other series focus on different arm positions or cues (such as keeping the elbows neutral or tucked), so they don’t prioritize the outward elbow alignment in the same way.
