ATG: Every Regression Counts… Lower Back! — Key Takeaways
Train your lower back weekly using a 4-part back extension sequence: braced hold with 100 lbs, flexion with 50 lbs (2:1 ratio), single-leg rotation, then lateral quadratus lumborum work — each performed to fatigue before progressing to the next.
Key takeaways
4-part back extension sequence trains all spinal planes in one set
4-part back extension sequence trains all spinal planes in one set
- Sequence: braced extension (100lb) → flexion (50lb) → rotation (bodyweight, one leg) → lateral QL work
- 2:1 load ratio — brace heavy, flex at half load — trains extension and flexion without equal spinal risk
Spinal flexion under load is trainable — just at half the extension load
Spinal flexion under load is trainable — just at half the extension load
- Rounding the spine with 50lb on a back extension machine is low-risk due to the reduced angle at the bottom position
- Avoiding flexion entirely leaves a gap in spinal resilience; controlled loading builds the ability that protects against real-world bending
Ankle mobility reduces lower back stress during squatting
Ankle mobility reduces lower back stress during squatting
- Hip flexors attach to the front of the lumbar spine — tight hip flexors and ankles both increase spinal load in the squat pattern
- ATG spine protocol includes ankle mobility work as a downstream fix for back vulnerability
