Back Extension #5 targets which spinal region for extension?

• A. Lumbar extension
• B. Cervical extension
• C. Thoracic extension
• D. Sacral extension

Answer: (C)

Back Extension #5 is designed to extend the spine primarily through the thoracic region, the mid-to-upper portion of the back. The movement emphasizes lifting and opening the chest from the thoracic spine while keeping the pelvis stable, which helps avoid over-arching the lower back and protects the lumbar area. This focus also counteracts rounded shoulders by extending the area between the shoulder blades rather than initiating the bend from the lumbar spine. Cervical extension would involve the neck and isn’t the main driver here, and sacral extension isn’t a distinct target in this exercise progression. So the extension work is centered in the thoracic spine.
