Why do you suppose anyone reads about health and fitness? My guess is that they want to improve both their health and fitness (kind of obvious I know)
But there has to be a point where you simply cannot continue to make measurable improvements…or at least there will be a point where more information, more effort, more planning will have diminishing returns.
So how do you know when you’ve read enough and done enough?
Is it a life long thing that can only be measured when you’ve reached some longevity goal (living to over 100 perhaps)
Is it a strength goal or endurance goal? (this wouldn’t make much sense unless you also included age as a dependent variable…in other words, your strength at age 65 will be less than your strength at age 25)
Is it just to know more than other people?
Is it to have good markers of health as defined by various governing medical organizations? If so what do you do when all of this looks good and you are in so called ‘optimal health’. Do you actually try to be better than this? (I think some people in fact do try to be better than optimal by striving to be more and more ‘fit’)
In my opinion people read about this stuff because they want to believe that they can take an active role in their own health and fitness (which of course you can considering you will also define your own health and fitness)
But I think problems arise when people do to much reading and theorizing and not enough ‘doing’. Information gathering can easily become more stressful and lead to a deterioration of health and fitness rather than helping you improve it.
If you find that you read more about fitness than you do about fitness you need to get your priorities in line.
30 mins of reading about what might be healthy will NEVER be as good for your health as a 30 min walk.
You’ve only got so many minutes in your life, so you might as well get the most bang for your buck out of each one.
