Z-Health Athletic Performance System Review :Behind The Curtains : Part 1

Now on to the the most important governing physiology principle that nobody talks about.

I’ve taken a ton of physiology classes over many many years, and it is incredibly rare this concept is even mentioned based about Physiology 101. Most trainers have even forgotten about this and if they have heard of it, they rarely use it in practice.  It is……..the SAID principle!

The SAID principle translated is
Adaptation to

This is roughly translated as “your body ALWAYS adapts to EXACTLY what you do, whether you realize it or not”

While this is not a new concept at all, it is forgotten about almost everywhere.

How does it work?

So if I bench press heavy, what do I get better at? Bench pressing heavy! I know this all seems incredibly obvious.

If I play football, will squatting heavy make me a better football player? According to the SAID principle, no. The question you are asking is TRANSFER. Will squatting heavy TRANSFER to the playing field? If it does make you a better football player (again, that is tricky to evaluate), it is POSITIVE TRANSFER. If it makes you a worse player, it is NEGATIVE TRANSFER.

Ironically, I think many top athletes who train and do screwy stuff in the weight room, find that it does NOT transfer to the playing field and this is a good thing since if it did it would make them a worse player. Many succeed IN SPITE of what they do.

Below is an article I wrote SAID Principle and Transfer for XL Athlete on this topic

Keep in mind that the SAID principle is true and “your body ALWAYS adapts to EXACTLY what you do, whether you realize it or not.   If you want more details, be sure to read the article above.

My buddy Todd has a great article on the SAID Principle too at the link below

What are your thoughts on the SAID principle?  How do you use it in your training?

Rock on
