Perfect Back Extension Technique

The back extension is a fundamental exercise for strengthening your erector spinae, glutes, and hamstrings. ChAIron's AI coaching ensures proper form for maximum posterior chain development and spinal health.

Step-by-Step Form Guide

  1. Machine Setup: Position yourself on a back extension bench with hips at the edge
  2. Starting Position: Cross arms over chest or place hands behind head
  3. Lower Phase: Slowly lower your torso until you feel a stretch in your hamstrings
  4. Extension Phase: Raise your torso back to neutral spine alignment

Common Mistakes to Avoid

  • Extending too far past neutral spine
  • Using momentum or bouncing
