Which commonly used equipment is used in both External Rotation Wide and External Rotation Closed?

• A. Footbar
• B. Resistance band
• C. Dumbbells
• D. Jumpboard

Answer: (D)

The key idea here is that external rotation work on the reformer relies on having a stable, anchored base to drive the movement and feel the resistance through the springs. The Jumpboard provides that reliable platform—it's attached to the footbar so your feet press into it, creating a solid anchor point while your arms perform the external rotation against the springs. This setup is used in both External Rotation Wide and External Rotation Closed because the essential need is the same: a consistent surface to push against with the legs to stabilize the lower body and allow the shoulder rotation to occur with controlled resistance. The other options don’t provide that same function in these specific shoulder rotation variations: the footbar is simply the base, resistance bands or dumbbells aren’t the standard reformer accessory for these movements, and jumpboard is the attachment that uniquely supports the required foot-grounded resistance in both cases.
