Back Extension #6 is named for which muscle engagement?

• A. Latissimus Dorsi Row
• B. Latissimus Pull Down
• C. Triceps Press
• D. Erector Spinae Target

Answer: (D)

The key idea is spinal extension—the muscle group that primarily brings the spine back upright during a back extension is the erector spinae. This long group runs along the spine and contract to straighten the back, resist flexion, and help you return from a bent position. In Back Extension #6, the movement is driven mainly by the erector spinae, with the hips and glutes providing some support, but not as the primary driver. Latissimus dorsi is a large back muscle that mainly handles shoulder movements like pulling the arm down and back, not the act of extending the spine. Triceps are elbow extensors and don’t participate in extending the spine. So the option that points to the erector spinae as the engaged muscle is the best fit for this exercise.
