Shaolin Iron Shirt (Twardy Chong) conditioning
This is the 'external' hardening training. He describes it as separate from the once-a-week Power Training. The objective is to condition the body so that you can receive hits without injury, ultimately being able to break hard objects. It's not just about physical toughness; it's also about mental fortitude — learning to control the pain response. The process is gradual and dangerous if rushed.
By repeatedly exposing the body to controlled impact, bones densify, connective tissues strengthen, and the nervous system desensitizes to pain, while the mind learns to stay calm under stress.
You slowly train your body to absorb strikes, control pain, and gradually begin breaking various objects.
