It always amazes me that FITNESS is a multi billion dollar industry... Yet a solid, concise and universal definition of fitness is difficult to nail down.
Just ask someone taking part in a physical exercise program, ikaria lean belly juice australia - talking to - or even someone in the fitness sector for that matter, to give you a clear meaning of fitness.
You will most likely be met with the "deer caught in the headlights" stare accompanied by absurd stammering.
If you get a remedy, it'll most likely be slanted toward the specific capabilities of an individual asked.
For example...

A marathon runner is going to define fitness in terms of cardiorespiratory and muscular endurance... A power-lifter is going to define fitness in terms of absolute strength... A bodybuilder will define fitness in conditions of muscle size and definition... etc.
But the vast majority of people taking part in a physical exercise program are not professional athletes worried about the improvement of just one physical ability.
Thus, basing the definition of yours of fitness on one specific physical ability does not result in a universal definition of fitness.
