In this video, I’m breaking down the science of the "Glass Jaw" vs the "Iron Chin" and explain why getting hit is actually making your punch resistance worse. I call this the Battery Theory, every concussion and heavy blow drains your battery, and once it's gone, it’s gone.
However, there is a way to lower the risk of getting knocked out. It is not about toughening your face. It is about strengthening the only muscle group that holds your head in place: your neck.
In this breakdown, I explain:
The "Battery Theory" and why brain damage is permanent.
Why Tucking Your Chin Protects You in Boxing
3 neck exercises for boxing to build a shock-absorbing neck.
The mouthguard tip that helps stabilize your jaw.
Why boxing footwork is the important defense.
Whether you are training for a fight or just learning how to box, these tips will help keep you safer in the ring.
