From the CrossFit Journal:
CrossFit's Three Fitness Standards
Before you read
on, know that our view of fitness is "contrarian", and iconoclastic
to no limit. People sometimes look down on our ideology, but let the haters
hate! (9 out of 10 times the hater is in way worse shape, based on any
standards.) You may have heard me say something like this, but we do not see
endurance athletes like marathoners and triathletes to be exemplars of fitness.
That in itself will already cause some debate. But I will continue anyway. Hate
on, haters!
Each of the
three models are critical to our community in evaluating an individual's
fitness. With that said, it warrants mention that I am not attempting to
legitimize this program through scientific principles. I am moreover sharing
the methods of a program whose legitimacy has been CLEARLY established through
the testimony of athletes, soldiers, cops, firefighters, and others whose lives
or livelihoods depend on fitness. (At this point I feel as though some of you
who may be reading this can be added to the testimonial list as well, but
correct me if I'm wrong.)
CrossFit's First Fitness Standard:
There are 10
recognized general physical skills, including cardiovascular/respiratory
endurance, stamina, strength, flexibility, power, coordination, agility,
balance, and accuracy. I will define these clearly later. You are as fit as you
are competent in each of these ten skills. A program develops fitness to the
extent that it improves each of these ten skills.
Importantly,
improvements in endurance, stamina, strength, and flexibility come about
through training. Training, referring to activity that improves performance
through a measurable organic change in the body. By contrast, improvements in
coordination, agility, balance, and accuracy come about through practice.
Practice, referring to activity that improves performance through changes in
the nervous system. Power and speed come about through training AND practice.
CrossFit's Second Fitness Standard:
This is the
"hopper principle". Picture a hopper loaded with an infinite number
of physical tasks written on ping pong balls. From Burpees (Rufees), to
thrusters, even throw some pilates and yoga in, to jumping, swimming, rowing,
running, anything you can imagine that is a physical task. Now randomly draw
any amount of ping pong balls. This suggests that your fitness can be measured
by your capacity to perform well at these tasks in relation to other
individuals.
This implies
fitness requires an ability to perform well at tasks, even unfamiliar tasks, all
combined in infinitely varying combinations. This encourages athletes to
disinvest in any routine of sets, reps, rest periods, exercises, etc.
Life frequently
provides largely unforeseeable challenges, and we should train for that by
keeping the training stimulus broad and constantly varied and progressive.
CrossFit's Third Fitness Standard:
There are three
main metabolic pathways that provide the energy for everything we do. They are
the phosphagen pathway, the glycolytic
pathway, and the oxidative pathway. The
first, phosphagen, dominated the highest-powered actvities, those that last
less than about 10 seconds. The glycolytic takes moderate-powered activities
lasting up to several minutes. The oxidative is responsible for the low-powered
activities, those lasting in excess in several minutes.
Total fitness
requires competency and training in all three of these metabolic engines.
Balancing the effects of these three pathways largely determines our
programming, and the how and why we do our "metabolic conditioning".
Favoring one or
two to the exclusion of the others and not recognizing the negative impact of
excessive oxidative pathway training are, arguably, the two most common faults
in the fitness world.
Conclusion
The motivation
for these three standards is simply to ensure the broadest and most inclusive
fitness possible. Our first model evaluates out efforts against a full range of
physical adaptations, the second focuses on breadth and depth of performance,
and the third is put in measures of time, power, and consequently energy
systems. Our specialty is not specializing. Life rewards this kind of fitness
and, on average, punishes the specialist. More on that later.
