MENTAL IMMUNITY
Use techniques developed in freediving record attempts to pressure–proof body & mind
How can we access mental and physical calm in a high-pressure, turbulent world?

The Mental Immune System
When immersed in stress, our innate responses are redundant, or even counterproductive. After all, they evolved for our lives as primitive apes, when tigers and other dangers were best confronted with hormones like adrenaline and cortisol. Nowadays though, 'fight or flight' does more harm than good when encountering modern stressors in our personal or professional lives.
We need to upgrade the system, to one that is aligned with our lives today, and allows us to regain calm and equanimity when life becomes pressurised. Most importantly, it has to be a method that works in the background, operated by the subconscious mind, just like our body's physical immune system doesn't require our involvement to ward off viruses and bacteria!
The Mental Immune System draws on breathing methods and mental techniques to reprogram the subconscious with the code to neutralising stress and anxiety, once and for all.

The Mental Immune System
How It Works
The body and mind have numerous feedback mechanisms, that can change your mental and emotional state. For example, did you know that the different muscles you can use in breathing send differing signals via nerves to the brain, activating or deactivating different areas of the brain itself?
Once you’ve learnt to hack these systems you can create and maintain a calmness that is not contrived, but instead regenerated continuously.
The difference is paramount. In the world of business, but also in our lives in general, the gulf between vision and success is greatly determined by how we deal with stressors and our fear of the unknown.
Don’t let your destiny be undermined by a lack of control over your mental and emotional state. Download the Mental Immune System to your life today.

Born of Water
The Mental Immune System was devised by William Trubridge, who has made a life out of redefining the human aquatic limits in the sport of Freediving (breath hold diving) during a 20-year career.
Unlike most other sports, Freediving requires complete mental and physical calm in order to succeed. Far below the surface, any panic or excitement will increase oxygen use, leading to a failed dive, or even worse.
Freediving is like a test tube experiment in stress-management, and the techniques that William has devised in his career have helped him in setting 18 world records, and becoming the first and only human to dive past a depth of 100 meters with no assistance of any kind.
In our modern lives, calmness is just as important when we dive into the difficulties we face at home and in the workplace. The powerful techniques of the Mental Immune System can be implemented here also, with the same effect as they have in the depths of the ocean.
System Goals
The blueprint is a double-pronged approach that uses both physical and mental techniques to dissipate existing stress, as well as to create barriers to its formation. This blueprint is then embedded into the subconscious mind to create a reflexive reaction to stress: the mental immune system.
- Create a blueprint of how to respond to stress, fear, and the unknown.
- Embed the method into your subconscious so that it becomes an automatic response (The Mental Immune System).
- Prove to yourself experientially that you’re capable of exceeding preconceptions of your own abilities
- Build a foundation for calm and stable work and personal life.
