What are the prescribed repetitions for Back Extension #3 Posterior Double?

• A. 8-12 reps
• B. 10-15 reps
• C. 15-20 reps
• D. 5-8 reps

Answer: (B)

The idea here is to use a repetition range that builds endurance and control in the posterior chain during a spinal extension exercise. For Back Extension #3 Posterior Double, the prescribed repetitions are ten to fifteen. This mid-range provides enough time under tension to strengthen the erector spinae, glutes, and related stabilizers while you maintain a neutral spine and anchored pelvis throughout each rep. Too few reps would shift emphasis toward maximal effort with heavier loading, which can compromise form on this move, and too many reps can fatigue the lower back and invite compensations. If you can’t finish ten to fifteen with good form, reduce the resistance or adjust the reps downward; if you’re completing them easily with perfect form, raise the resistance to keep it challenging.
