There is a fairly common pattern in this field where folks go through about three distinct stages. it true of other areas. 1. You know that you know nothing: here you pretty much just use someone else's canned workouts since you don't know what you're doing 2. You know just enough to be dangerous. This is when everybody starts overcomplicating things. You see these insanely complicated training programs and periodization schemes. Lots of charts, graphs and flowcharts. 3. You realize that the above doesn't matter 999 times out of 1000 and you go back to keeping it simple. You realize that hard work on the basics + talent + time > everything else.
