Don your helmets, take your creatine and CBD as we are headed straight down the nerd chute hard about the concept of homeostasis – how to be a more badass human that can handle all sorts of stressors, train harder, recovery faster, and improve your health in the process.

I’ve hinted at what may happen with age related to the concept of adaptive homeostasis.

I know that is a nerdy marble sandwich, but it has important ramifications.

Here is another direct quote:

“…As individuals age, the expansion / contractive ability of the adaptive homeostatic range diminishes, this decline may contribute to the high incidence of disease development amongst elderly population.” (Pomatto & Davies 2017)

As you age, if you are not actively training, you get worse.

Here is a graph to illustrate:

As you can see, on the bottom (x axis) is age; the further to the right you go, the older you are.

What you see is that your capacity to buffer stressors gets less. The yellow “adaptive zone” is getting smaller and smaller.

The assumption here is that the Planet Fitness shopping cart licker is not training.

  • If you do not train these systems, they will get worse.
  • If you train them, just like fitness, you can get better at them; thus, keeping a huge portion of the adaptive reserves.
A bigger adaptive zone (buffer zone) allows you to absorb more stress before you break.

Just like the analogy I used a few newsletters back about ceramics; they are very strong but fragile.

You want strength without becoming rigid.

You want to be lean without having to eat every meal for the rest of your life out of a Tupperware container.

Ugh. Pleeeeeeeeeze. That is not a life.

Spend a bit of time to train up your adaptive reserves for enhanced health and more robustness as a human being.

This allows you to train harder and absorb more stressors that life will throw at you.

No one is immune from life kicking you in the jimmy at some point.

Are you going to be ready?

Will you bend or break?
