Which hold duration and intensity are prescribed for the erector spinae exercise?

• A. 3 intensity for a 6-8 second hold
• B. 3 intensity for a 4-6 second hold
• C. 3,3,3
• D. 3,5,7

Answer: (A)

The idea is to train the back extensors with a steady, controlled contraction that you can hold long enough to challenge endurance without losing form. The best prescription is a moderate effort (level 3) held for 6 to 8 seconds. This duration provides meaningful time under tension to strengthen the erector spinae and improve spinal stability, while still allowing you to maintain a neutral spine and proper technique throughout the hold. A shorter hold, like 4 to 6 seconds, reduces the time under tension and is less effective for building endurance in the back muscles. The other patterns described (such as sequences or varying counts) don’t reflect a single sustained hold at a specific duration, so they don’t match the intended training stimulus for this exercise.
