Self Defence in Surrey 26

Functional Fitness and Self-Protection Training

First established in 2006, Dynamis Gym is focussed on helping people to do the extraordinary, by thriving in conflict situations. 

Led by professional coaches with a learner-focussed approach, we teach across all three dimensions of personal safety:  emotional, psychological and physical.

In weekly classes and regular seminars, our team explores the 'universal human phobia' of interpersonal conflict.  We teach practical self-protection tactics in an atmosphere focussed on learning, where people of all kinds can improve their confidence-in-conflict and enhance their functional fitness to meet personal safety challenges.

Weekly Classes in Penrith

Our weekly classes cover a breadth of common scenarios which people may face.  Over time, weekly class attendees get the opportunity to develop a broad repertoire of skills for personal safety, developing from management of personal space and boundary-setting language, through to survival from common types of assault and on into more specific domains such as when we must fight from the ground, or in confined spaces, or when there may be weapons introduced into a situation.  Your coaching team cycle through these varied scenarios, allowing you to develop coping skills and definitive tactics to help you grow in confidence.

Experiences at Dynamis Gym...

You have already inspired me to search out more information.  

Definitely an excellent class on Saturday, I felt very privileged to be part of it.  Breaking down how your spirit-mind-body reacts to an attack really appeals to me.   Although there were a lot of new ideas to think about it all makes absolute sense and it all came back to quite simple outcome, a tactic that is effective, easy to learn and worked for me. 

To understand how 'real' attacks occur and to drill them to be better prepared is worth doing. 

Something I need to give myself is the permission to fight back - that first directive you spoke about.

It may take a second class to get over the giggles and feeling daft, knowing now what attitude to go into the training with to get the most out of it.   Even covering the exactly the same things you showed us on Saturday, I'm sure there would be something new to pick up. Can't wait for more!


Environmental Scientist

I am a 68 year old male, former Managing Director, who is reasonably fit but I had lost confidence in myself.

I believed that a situation could arise when I would need to defend myself, so via the internet I contacted Dynamis Gym and made contact with Gerard.

Over the 12 weeks of training I have gone from being a total novice in the knowledge of self defence, to someone who is prepared to protect himself and family. 

From the first visit to Gerard I have been trained to be aware of the procedures to defuse and self protect myself from the threat of attack on my person.

I have gained skills and a belief in myself that  should any future confrontation occur I should  be able to defuse the conflict and  protect myself. 

I thoroughly recommend the principles and teaching I received from Gerard to anyone who needs to rebuild their confidence and regain their self respect.


Retired Managing Director

I knew I was motivated to train at  Dynamis Gym on my very first lesson. The mixture of fitness training, self-defence, and partner based drills is really enjoyable and after training at the Dynamis Gym for a few months I already feel much fitter and more confident.

The Dynamis Gym attracts a wide range of people, from beginners interested in improving their fitness and in modern, practicable self-defence training, to experienced practitioners from a variety of martial arts backgrounds. Everyone seems to get something from the training.

One of the outstanding features of  Dynamis Gym is the high level of instruction. The instructor is highly qualified and also has a real ability to teach. I am constantly amazed at the variety of self-defence scenarios that are used, the effectiveness of the responses taught, and the ability of the instructor to give advice and to motivate people to train hard.

My advice to anyone looking for a gym, whether it is to improve their fitness or to learn self-defence, or both, would be to try Dynamis Gym out for themselves. It is a friendly gym with a great mix of people and the instruction is of a very high standard.

“Since 1986, I have studied all around the world, exploring systems and meeting instructors from a variety of traditions and methodologies.  I studied Japanese at university, studied the old texts, lived in the culture.  My goal was then and still is now, to be able to answer the difficult questions about interpersonal conflict in the most meaningful, helpful way possible for my students.  

I have learned, and earned, my craft from some of the pre-eminent personal safety coaches in the world..  
In my corporate work, I primarily meet healthcare, education, security and community teams - workers of all kinds, contact professionals from the security, financial services and property sectors and from time to time I work with survivors of sexual assault or bullying.  

Dynamis Gym is the vital testing ground I established in 2006 where people with varying experiences with conflict come together to explore the reality of violence, aggression and the means to stop it or prevent it.  The environment is inherently a safe one where health, wellbeing (and injury prevention) are valued.

I often have only limited time with my students, but I am always inspired when the attitudes and methodology we use as trainers bring clarity to the problems of confrontation our people face in their life and work.

Where we have more time with individuals on a private basis, I have seen them transformed by our physical and tactical training - they emerge more confident, more aware, with fewer limiting beliefs.

My aim is that the training I provide is accessible and effective for every person who seeks it out - regardless of age, gender, size, occupation, past experience or expectations.”

We teach the 9 Attitudes for Personal Safety:

The Relaxed Attitude

Activated when there is nothing to worry about, when in a place or among people who make you feel safe and secure.  An important anchor for all that is good and worth protecting in life.

The Alert Attitude

Activated when our innate body-mind system detects some anomaly in our environment which draws our attention and demands that we examine it closely to review if we are safe.

The Preventive Attitude

Activated when we identify that an anomaly in our environment is a risk to our safety and we actively need to do something to reduce the threat of it becoming harmful to us.

The Survival Attitude

Activated when our instinctive protective mechanisms have fired under a sudden assault and and we cognitively seek to leverage those reflexes to survive the inital collision.

The Reversal Attitude

Activated at the moment when, fuelled by emotion, we physically, psychologically and emotionally regain balance and transition into productive movement to stop or slow the assailant.

The Engagement Attitude

Activated when we press an opportunity created by survival and reversal and exploit it by causing dysfunction in the assailant, in order to meet our protection goal.

The Escape Attitude

Activated when our protection goal is to move towards safety and away from the assailant immediately as the opportunity presents itself.

The Control Attitude

Activated when we cannot simply move towards safety and away from the assailant, usually in complex situations regarding some duty of care to them or others.

The Harm Attitude

Activated when the only viable option to create safety is to definitively stop the assailant from being able to continue to cause harm.

N.B.  Not all of our sessions reach this level of kinetic intensity!

The clips above are from some of our embryonic scenario-driven training sessions at Dynamis Gym, incorporating Impact Reduction Gear (see ) where you can see us using standup-clinch-ground tactics informed by the needs of the average person in a seriously violent confrontation.  Notice that the prerogative is to get up from the ground as soon as possible, where possible, for example - this is where self-protection training may differ from sport-oriented practices (as comprehensive and solid as those disciplines are).  You will also see where we have picked a scenario from the news, or from released CCTV and reverse-engineered a whole training evolution from the circumstances to produce an enjoyable, rewarding and educational self-protection training experience.
