WHAT IS CROSSFIT?

CrossFit is the principal strength and conditioning program for many police academies and tactical operations teams, military special operations units, champion martial artists, and hundreds of other elite and professional athletes worldwide.

Our program delivers a fitness that is, by design, broad, general, and inclusive. Our specialty is not specializing. Combat, survival, many sports, and life reward this kind of fitness and, on average, punish the specialist.

The CrossFit program is designed for universal scalability making it the perfect application for any committed individual regardless of experience. We’ve used our same routines for elderly individuals with heart disease and cage fighters one month out from televised bouts. We scale load and intensity; we don’t change programs.

The needs of Olympic athletes and our grandparents differ by degree not kind. Our terrorist hunters, skiers, mountain bike riders and housewives have found their best fitness from the same regimen.

 WHAT IS FITNESS?

Crossfit’s First Fitness Standard

There are ten recognized general physical skills. They are cardiovascular/respiratory endurance, stamina, strength, flexibility, power, coordination, agility, balance, and accuracy. (See “General Physical Skills”, listed below, for definitions.) You are as fit as you are competent in each of these ten skills. A regimen 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 refers 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 refers to activity that improves performance through changes in the nervous system. Power and speed are adaptations of both training and practice.

Crossfit’s Second Fitness Standard

The essence of this model is the view that fitness is about performing well at any and every task imaginable. Pictureahopper loaded with an infinite number ofphysical challengeswhere no selective mechanism is operative, and being asked to perform fetes randomly drawn from the hopper. This model suggests that your fitness can be measured by your capacity to perform well at these tasks in relation to other individuals.

The implication here is that fitness requires an ability to perform well at all tasks, even unfamiliar tasks, tasks combined in infinitely varying combinations. In practice this encourages the athlete to disinvest in any set notions of sets, rest periods, reps, exercises, order of exercises, routines, periodization, etc. Nature frequently provides largely unforeseeable challenges; train for that by striving to keep the training stimulus broad and constantly varied.

Crossfit’s Third Fitness Standard

There are three metabolic pathways that provide the energy for all human action. These “metabolic engines” are known as the phosphagen pathway, the glycolytic pathway, and the oxidative pathway.

The first, the phosphagen, dominates the highest-powered activities, those that last less than about ten seconds. The second pathway, the glycolytic,  dominates  moderate-powered  activities,  those  that  last up to several minutes.

10 GENERAL PHYSICAL SKILLS

If your goal is optimum physical competence then all the general physical skills must be considered:

1. Cardiovascular/respiratory endurance - The ability of body systems to gather, process, and deliver oxygen.

2. Stamina - The ability of body systems to process, deliver, store, and utilize energy.

3. Strength - The ability of a muscular unit, or combination of muscular units, to apply force.

4. Flexibility - the ability to maximize the range of motion at a given joint.

5. Power - The ability of a muscular unit, or combination of muscular units, to apply maximum force in minimum time.

6. Speed - The ability to minimize the time cycle of a repeated movement.

7. Coordination - The ability to combine several distinct movement patterns into a singular distinct movement.

8. Agility - The ability to minimize transition time from one movement pattern to another.

9. Balance - The ability to control the placement of the bodies center of gravity in relation to its support base.

10. Accuracy - The ability to control movement in a given direction or at a given intensity
