Episode notes
Train The Spine Like Any Other Tissue
- Loading a natural spinal range produces positive tissue adaptations when dosed sensibly.
- Treat spine loading like any other muscle: progress range and load instead of avoiding it out of fear.
How Fear Becomes A Movement
- 'Glass back' describes evangelical fear that spreads from personal injury stories into prescriptive rules.
- That mindset narrows self-efficacy and makes people overestimate risk and under-train their capabilities.
Use Cardio To Protect Your Back
- Add cardiovascular work like running or rowing to preserve disc health and resilience.
- Use cardio to build fatigue resistance so you don't get injured late in training or competition.
