So many people live with a rigid, protective posture because they’ve heard that spinal bending is “bad.” But that’s not how the body works.
Your spine is a dynamic, adaptable structure.
It’s supposed to bend.
It’s supposed to move.
And when trained properly, it can handle WAY more than you think.
The key?
1. Work within your current ability
2. Train through ranges you can control
3. Gradually build up exposure over time
This Jefferson curl progression is a great place to start if you want a spine that feels capable, not fragile.
Move with intention. Build resilience. Don’t fear flexion.
