What is Fitness?

What is Fitness?

One of the reasons CrossFit has become so popular is it finally took the word fitness and defined it to three standards which can be observed, measured, and retested.  Which before CrossFit fitness was defined as “the condition of being physically fit and healthy”.  That definition is subject to interpretation and not able to be retested for progress. The three standards CrossFit defined fitness by are the 10 general physical skills, all inclusive, utilizing all three metabolic pathways, and the wellness continuum. 

The 10 General Physical Skills

The 10 general physical skills are develop either through training, practice or the combination of both training and practice.  What is accomplished through training is cardiovascular endurance, stamina, strength, and flexibility. While improvements in coordination, agility, balance, and accuracy are from practice.  The last two power and speed need a combination of training and practice. 

All Inclusive

In the second standard of being all inclusive is to be able to perform any task through at you. To go for a 10k run, lift 400lb deadlift and everything in between.  To be able in all workouts, time domains, exercises, reps, and periodization. 

Metabolic Engines


In the third standard you want to work all three metabolic engines.  The phosphates, glycolytic and the oxidative pathway.  Each one is utilized in crossfit with lifting, sprints, intervals, and long range workouts.

Sickness to Fitness 

These three standards gives the broadest and most general fitness possible  CrossFit specialty is not specializing.  The goal is to move from sickness to wellness to fitness.  A fitness regimen that does not support health is not CrossFit.
