WHAT IS FITNESS
CrossFit defines fitness as an amalgamation of three different models.
Model 1: 10 General Physical Fitness Skills
The first model holds that a person is only as fit as he or she is competent within each of these skills:
- Endurance – The ability of body systems to gather, process and deliver oxygen (cardiovascular/respiratory endurance).
- Stamina – The ability of body systems to process, deliver, store and utilize energy (capacity to maintain repetitive muscular movements).
- Strength – The ability of a muscular unit, or combination of muscular units, to apply force.
- Flexibility – The ability to maximize the range of motion at a given joint.
- Power – The ability of a muscular unit, or combination of units, to apply maximum force in minimum time.
- Speed – The ability to minimize the time cycle of a repeated movement.
- Coordination – The ability to combine several distinct movement patterns into a single, distinct movement.
- Agility – The ability to minimize transition time from one movement pattern to another.
- Balance – The ability to control the placement of the body’s center of gravity in relation to its support base.
- Accuracy – The ability to control movement in a given direction or at a given intensity.
Model 2: The Hopper
The second belief holds that fitness is broad and inclusive. A “fit” person should be able to perform well at a broad range of physical tasks.
Imagine a lottery wheel or “hopper” filled with every imaginable physical fitness task (ie. running 10km, dead-lifting bodyweight, rollerblading down a hill, high-diving 10m, climbing a 20ft tree). A random number of these tasks are pulled from the hopper and are performed by a group of athletes. The person most capable, across the board, at completing these tasks is deemed fittest.
Model 3: Energy Pathways
The third belief states that fitness should carry through all known and widely accepted energy pathways. An athlete should be able to perform well in activities lasting over various time periods, from very short to very long.
