Back Extension #3 is commonly referred to as which nickname?

• A. Posterior Double
• B. Anterior Double
• C. Lateral Extension
• D. Superior Pull

Answer: (A)

The idea being tested is how nicknames for Reformer exercises reflect which part of the body is working and how the movement goes. Back Extension #3 specifically targets the muscles on the back side of the body—the spinal extensors along with the posterior chain as you extend the spine and hips. That focus is captured by the nickname Posterior Double, signaling a back-side (posterior) action with two coordinated extension components (spine and hips) working together. The other options describe movements or emphases that don’t match this variation: an anterior focus would imply front-side work, a lateral extension would involve side bending, and a superior pull suggests an upward pulling action that isn’t characteristic of this back-extending move.
