Important points:
1 - Don't confuse a "health club" with a gym. 2 - Don't confuse a "personal fitness trainer" with an athletic trainer. 3 - Most of all.... Don't confuse Performance and Results.
If you actually really care about Performance and training - I would suggest you start by learning the fundamentals of training. You MUST own your own training. And to do that you need to be informed. The author obviously didn't do any of this work as he just ran from "expert" to "expert" rather than taking personal responsibility. A simple rule of thumb.... if you're not talking about periodization, you're working with the wrong person (and doing it wrong).
Kevin Brown was one of the best PTs on the west coast and I'm incredibly fortunate to have worked with him. He was a huge loss to the community, and to his friends and family. But he wasn't the sort of 'holy man' that is implied in this piece. Unlike everyone else who the author worked with throughout his efforts, Kevin was just a highly skilled, highly trained, athletic performance professional. These people exist throughout the athletic world - including working as trainers.
So make the effort.
1 - Educate yourself on performance and athletic training principles.
2 - Fine a serious professional and work with them.
If you're not up for the above - then accept that you're not going to get the "magical" results you dream of. That's life.
Oh... and a fundamental flaw throughout this piece is the idea that there is some sort of "shortcut" to high performing physical fitness and athletic performance. Other than using PEDs there is no shortcut. And even PEDs are only effective if you ALSO take no shortcuts in your training.
