Myokines are one of the biggest discoveries in exercise science.
For a long time, we thought muscles were just here to move the body.
But now we know: muscles are also an endocrine organ â the largest one you have.
Every time your muscles contract, they release chemical messengers called myokines.
These signals travel through the body and influence your brain, metabolism, immune system, bones, recovery and adaptation.
So your workout is not just âburning caloriesâ.
Itâs your body sending instructions to become stronger, more resilient and better prepared for life.
If scientists could put all of that into a pill, it would probably become one of the most valuable medicines in the world.
Until then, your body makes it for free.
You just have to move.
