It often amazes me that FITNESS is a multi billion dollar industry... Yet a great, concise and universal definition of fitness is tough to nail down.
Just ask a person taking part in a physical exercise program, and even someone in the fitness market for that matter, to give you an apparent definition of health.
You will most likely be met with the "deer seen in the headlights" gaze accompanied - https://www.Google.com/search?hl=en&gl=us&tbm=nws&q=gaze%20accompanied&b... by absurd stammering.
If you do get a solution, it'll more than likely be slanted toward the specific capabilities of an individual asked.
For example...
A marathon runner is going to define fitness in terms of muscular and exipure medical reviews ( just click the following internet page - https://www.heraldnet.com/national-marketplace/exipure-reviews-every-cus... ) cardiorespiratory endurance... A power-lifter will define fitness in conditions of absolute strength... A bodybuilder will define fitness in conditions of muscle size and definition... etc.
But the vast majority of people participating in a physical exercise routine are not professional athletes concerned with the improvement of only one physical ability.
Thus, basing the definition of yours of fitness on a single certain physical ability doesn't result in a universal definition of fitness.
