An Introduction to Parkour and its Synergy with CST Methodologies
By Dan Edwardes copyright © Parkour Generations Ltd.
Le Parkour (1), though crystallised into its current guise by Frenchmen David Belle and Yann Hnautra sometime in the 1980s, is a practice the roots of which precede records. It has drawn on a myriad of sources, been inspired by a number of notable individuals and evolved through several traditions to arrive at the modern discipline now referred to as parkour or free-running. Names and labels come and go, of course, and the outward visage of this discipline has shifted and modified itself countless times. However, behind whatever appearance has been fashionable at the time, at its core there has always existed an eternal constant – the means, the end, the method and the goal of parkour: Movement.
It is clear that parkour and the Circular Strength Training® (CST) System share this essential understanding of the intrinsic worth of non-linear, dynamic movement. 

There has arisen fairly recently another training methodology that also focuses on mobility and motion in the body, though with its primary emphasis on health, fitness and longevity. This paradigm, known as Circular Strength Training® (CST), was brought into life by Scott Sonnon, a US National Coach and Master of Sports who, in his time, has also won Sambo International Championships - a Russian grappling discipline in which bouts can still be won by breaking the opponent’s limbs: needless to say, a difficult tournament to win. Using terms such as Body-Flow, Flowfit®, and Kinetic Chains of Movement it is readily apparent that Sonnon’s approach to training the body through corrected movement is not too distant a cousin of parkour.
Though they have both evolved as entirely separate disciplines, it is clear that parkour and CST methodologies share this essential understanding of the intrinsic worth of non-linear, dynamic movement. The overlapping fields between CST and parkour are numerous, and to identify and detail them all is beyond the scope of one article. Instead, let us find a model for comparison. Coach Sonnon has usefully identified three CST Fitness Standards in a recent article, and even a cursory glance at these benchmarks soon reveals the synergy that exists between parkour and the Circular Strength Training® paradigm.
The first Fitness Standard is described in his Big Book of Clubbell® Training as Work Capacity to Sophistication to Specificity to Flow. If we look at the fundamental physical attributes CST aims to develop, Coach Sonnon informs us that it “includes the critical elements of coordination, body control, agility, balance, accuracy, timing, rhythm and sensitivity which come from practice.” Exactly the same can be said of parkour, in which every movement requires and encourages development of most, if not all, of these elements.
He goes on to say “CST measures fitness as the ability to recruit maximal multi-joint efficiency to move through multiple planes of motion with greater and greater ease compared to previous attempts.” Again, simply replace the acronym ‘CST’ with the word ‘parkour’ and you have an almost perfect definition of one of the principle goals of the discipline.
Of course, a wide range of sports and physical practices could also lay claim to the sophisticated goals that CST lays before us. The crucial difference, however, between most of these and parkour is to be found in the training and practice methods themselves. Both in training and in practice – for the two are very different things – the traceur is never attempting to work any part of his body in isolation, nor is he ever developing anything other than the most functional attributes and skills.
The traceur does not bring weights or clumsy machinery to his sessions: his body is his one and only tool. The principal practice for a practitioner of parkour is to repeat and refine the movements of parkour, improving tensile strength, flexibility, and coordination as he goes, greasing the grooves in the musculature while increasing neuromuscular efficiency. The importance of proprioception cannot be overstated, and is constantly improved through balance exercises, night-training (read ‘sensory deprivation’), and spatial awareness drills.
This ‘natural’ approach to training goes back to the lifestyles of ancient tribal cultures, perhaps first properly researched from a fitness perspective by George Hebert (1875-1957), a pivotal figure in the history of physical education in the West who was struck by the natural attributes of the indigenous peoples of Africa, among whom no specific ‘training regimen’ was ever encouraged or enforced – Hebert noted that merely leading their natural lives of physicality and dynamism produced incredible specimens possessed of exceptional functional strength and agility.
His ‘Natural Method’, which many regard as one of the forerunners of parkour, was a means by which to reproduce these effects in industrialised societies by “promoting the qualities of organic resistance, muscularity and speed, towards being able to walk, run, jump, move quadrupedally, to climb, to walk in balance, to throw, lift, defend yourself and to swim.” Indeed, quadrupedal movement – moving with one’s weight evenly distributed between all four limbs – is a tool regularly used when warming-up in preparation for parkour.
Quadrupedal movement as training preparation
Just as in CST, parkour practice encourages a gradual sophistication of attributes, through detailed specification as the freerunner goes deeply into the intricacy of his movement, towards an unconscious mastery of his own abilities. To achieve ‘the flow’ in movement is one of the Holy Grails of parkour: to link skills together into a seamless, dynamic whole facilitating instinctual movement over any terrain. (If this sounds anything at all like a kinetic chain, that is precisely because it is. In effect, parkour could be described as one long, explosive kinetic chain of integrated movements!) It is important to understand that parkour is not simply a collection of techniques – rather, parkour occurs when one is moving over terrain in a spontaneous and non-predictive manner, paralleling the ‘flow beyond thought’ of Scott Sonnon’s Prasara Body-Flow. To have this capacity to move at any time, along any plane, gracefully and efficiently is what the traceur seeks. And he trains for it by doing it.
The second Fitness Standard outlined in CST is the expedient ability to acquire efficiency in new skills, and more importantly innovatively create new skills. Coach Sonnon goes on to explain that a ‘skill’ is not something acquired by the mere rote repetition of a specific function, but is a result of physical, mental and emotional integration and is something best measured by how effortlessly one can complete a task. Efficiency, demonstrated through stealth training and lightness, is central to parkour. We aim to ‘make silence’ as we train, to go unnoticed as we pass through any environment and to leave no trace of our passing as we go. And anyone who practises parkour soon realises just how powerful the mind can be in restricting one’s own potential, as the art shines a bright spotlight on how much fear-reactivity hinders our every move: parkour is as much mental and emotional as it is physical.
And once this fear-reactivity is overcome, good parkour make impossible actions seem not only possible but also quite effortless. Obstacles and barriers are traversed in the blink of an eye, difficult terrain negotiated without the impediment of fear or anxiety, and what most would see as impediments to movement become partners and springboards along one’s route.
Coach Sonnon goes on to say that “CST’s secondary goal is to tap the idiosyncratic genius of each individual’s physical expression of fitness.” And this is no less true of parkour; innovation and adaptation are crucial. Parkour is often wrongly described as an urban sport or art, when the truth is that parkour aims to teach the individual to be able to adapt his movement to absolutely any environment, and in any situation. Practitioners are encouraged to train in built-up areas as well as in rural surroundings, upon coastal rock formations, within forests and jungles; indeed, anywhere that presents the opportunity for movement.
Finally, we come to Fitness Standard Three: An Effective ratio of restorative forces to work forces. Here it is outlined that fitness must be measured in terms of one’s ability to perform a chosen task at any given time. Effectively, what this means is that we must have balance in our training methods in order to maintain a constant and high level of health and fitness, so that we are able to act whenever we want or need to. Parkour is a truly holistic discipline that offers the practitioner a new way to observe and manage the relationships between himself and his every environment, encouraging him always to be aware of the possibilities for movement and to appraise his own ratio of capacity to potential.
We must constantly ask the question of ourselves: just what can I do and how close am I to being able to do it? The goal of training is to improve our standard of living, to enable us to get more from every moment and every activity, to help us explore our innate potential: To make us more capable, in the true sense of the word. A training method that detracts from this in any way is flawed at a fundamental level.

Parkour, as is commonly noted by newcomers, reaches into every aspect of one’s daily life. Many voice this as ‘having their eyes opened’. Practitioners soon come to look at their surroundings in a completely different and unfettered way. They step outside of the box and find that, in fact, there is no box and never was. It raises one’s awareness of the inefficiency and wasted effort that accompany most of one’s everyday movements. One learns to walk properly, to maximise the use of space on a crowded street, to foresee and avoid obstacles on a journey; in short, one learns to flow with the currents of life in a more harmonious and beneficial manner so that, as Coach Sonnon points out, “your very daily activities themselves become an extension of your training and practice.” This change comes about as much mentally as it does physically for, of course, the two are inextricably interwoven.
It is evident from this brief evaluation of the Fitness Standards espoused by Coach Sonnon that there is a powerful resonance between parkour and the various elements underlying the Body-Flow: Freedom From Fear-Reactivity, Intu-Flow Longevity and Prasara Yoga. Practitioners of the CST paradigm and traceurs alike have noticed the connecting tissues between the disciplines, and indeed there are already those who incorporate both into their own training regimes. They sit well together, for in a sense they are cousins: Both based on continual, non-linear, non-contained movement; both dynamic and explosive; both concerned with overcoming fear-reactivity. They have evolved separately, yes, but separate and parallel is a more accurate description.
We all harbour immense potential for extraordinary activity. We all possess the innate ability to move with the seemingly superhuman attributes that both parkour and CST develop. The truth is, of course, that there is nothing superhuman about these activities – and there are no secrets either. Diligent, intelligent practise and focused, regular training will bring about the realisation of this potential. Whether you walk the omni-directional paths of parkour or seek to unleash your own Bodyflow through CST, you are on a road of self-improvement to which there is no end in sight.
Definitions
(1) The invented word ‘parkour’ originates from the French parcours du combattant, a phrase meaning ‘course of the fighter’ which was the original term for the military-style obstacle courses now used by armed forces around the world. From parcours, meaning ‘course’ came the altered ‘Parkour’. David Belle credits his friend Hubert Kounde for having coined the word.

Outstanding essay, thank you Dan.
As a rock climber of 30+years, the same parallelism runs through that sport as well. After all, the truth is the truth.
:)

hello,
coach sonnon, this is an interesting article. it indeed seems that cst and parkour (and climbing) have a great deal in common.
approach (incremental increases) and “philosophy” (sophistication being like a goal unto itself).
it is great that there is room for several “right” answers!
thanks

This is similar to what I experienced while attending a 5-day MovNat seminar a couple months ago. There are many correlations between CST and MovNat, but like Dan said of Parkour “They have evolved separately, yes, but separate and parallel is a more accurate description.”
I see some powerful possibilities in regard to integration of CST with a natural movement system like Parkour or MovNat.
By John Sifferman on Nov 17, 2009
John, 100%. One of the systems I once promoted was Zdorovye: The Russian Natural Movement System. What came under hot debate was the designation of “natural”. Or an easier elephant to start dissecting is, “explain an unnatural movement.” When you start examining the use of the term “natural” you imply that there are “unnatural” movements. If you imply “movements in natural settings,” one can still argue, a manmade/synthetic environment is still “natural” - as man is inextricably always within “nature.” Movement is either inefficient (cost poor) and ineffective (results poor), inefficient/effective, efficient/ineffective, or efficient/effective (cost and results rich.) There is no unnatural.
By Scott Sonnon on Nov 17, 2009
Exactly, Scott.
At the MovNat seminar, I was taught a simpler approach to defining movement as natural (the ice pick, not the scalpel). One aspect of MovNat’s definition of natural is that movement must be practical or useful for some purpose - that it must accomplish a goal, whether doing so efficiently, effectively, or not. A natural movement can still be “naturally bad” or “naturally good/optimum.”
So yes, all movement is natural, there is no unnatural. We express our movement quite naturally, even if it’s “naturally bad” (ineffective or inefficient.)
But semantics aside, I don’t see MovNat or Parkour as methods of getting better at moving naturally, per se (even though, technically that’s what happens as specific skills improve). Natural movement is often incorrectly treated like an attribute that can be built up, much like conditioning - almost like moving naturally is a side-effect of certain training methods. When in reality, it’s just a collection of skills taught through a specific coaching system like any martial art or physical practice.
It’s an immensely valuable practice for anyone, but it isn’t exempt from the laws of conditioning, which is why CST principles can so beautifully infuse into one of these movement systems to better refine them.
By John Sifferman on Nov 17, 2009
Impractical movement is not natural? Anthropologists would disagree. Dance is as old as hunting, our first form of communication. All human movement is natural.
I don’t see these as semantics, but as critical distinctions. Every exercise must be for a purpose. Is it effective (results / risk) for that purpose? Is it efficient (total/useful work) for that purpose?
Therefore, we have only four classifications of movement potential:
1. inefficient ineffective: high risk, low results, high total work, low useful work.
2. inefficient effective: high results, low risk, high total work, low useful work.
3. efficient ineffective: high risk, low results, low total work, high useful work.
4. efficient effective: low risk, high results, low total work, high useful work.
Even inefficiently ineffective work is still natural. ;) “Natural” movement is the boondoggle of the functional fitness genre: a meaningless, pejorative term meant to demonize methods its proponents deem opposite of their purpose. But that’s a doctrinal difference alone.
There are stronger (more efficiently effective) arguments which can be used rather than castigating a movement as “unnatural.”
By Scott Sonnon on Nov 17, 2009
MovNat’s definition of natural, not mine, Scott.
By John Sifferman on Nov 17, 2009
John, I never stated it as your argument, and used the pronoun “we” because you are part of the CST Cadre.
Words alone limit us. Words shape our imagination. Only our imagination is limitless. Therefore, we must critical scrutinize the word choices we make to ensure that they FREE us rather than enslave us.
By Scott Sonnon on Nov 17, 2009
This is exactly why I think CST would integrate very well with a system like MovNat or Parkour.
By John Sifferman on Nov 17, 2009
Scott,
In your example above, would you classify:
strength training as inefficient effective
and
CST / natural movement as efficient effective
???
My Chaos Training Manual tried to expose the limitations of conventional, linear patterned, spatially fixed strength training movements.
The chaos supplemental means I created attempted to further bridge the gap between GPP and SPP.
GPP ===> CHAOS ===> SPP
There, in my limited, novice understanding, now another level of progression:
GPP ===> CHAOS ===> FLOW ===> SPP
By Smitty on Nov 17, 2009
Smitty,
We need to differentiate between form and function. All movements are natural. All movements are skills. All skills have a sliding scale of good form (efficient) to bad form (inefficient). Proper form with those skills are on a sliding scale of effective to ineffective at producing the intended results. ALL skills have (bio)mechanics which are sound and unsound.
The function or purpose of the skill differs.
CAN the skill accomplish the objective at all (is it effective)?
For example, though frequently used by scholastic basketball athletes, the back squat is an ineffective exercise for increasing high-jump height.
Does the skill inefficiently or efficiently accomplish the objective/purpose?
For example, for developing core strength, you can attempt to use sit-ups, but even with good form, these fail to efficiently develop the rectus since the tissue is designed to resist extension.
Identify the purpose.
Identify effective exercise skills to achieve that purpose.
Select the most efficient skills from those which are effective to achieve the intended results.
