From the readily available spin class, to the high intensity group training sessions, most seeking for their new “next level” of fitness will ultimately fail. This will not be for lack of effort on their part, moreover, it is being without significant insight of long term fitness success.
Why?
Long term progressive fitness means a clearer understanding of personal fitness value, plus the necessary efforts to address one’s progressive needs. This begins by first understanding the difference between Working Capacity (value) and WorkingIntensity (effort).
Working Capacity will be the tolerable work level you can currently perform, recover, and repeat.
Working intensity will be the performance of your maximal effort to meet a higher stimulus of stress, thus successfully creating your new working threshold (fitness) level.
