🧠 Exercise Isn't Motivation — It’s Comprehension
A well-known 2013 study by Bente Klarlund Pedersen changed how we understand exercise.
(long post, worth reading)
The big idea:
Your muscles are not just for movement. They act like an organ that talks to the rest of your body.
🦵 Your Muscles Are an Organ (The Largest One)
- Skeletal muscle is the largest organ in your body
- We usually think of muscles only:
- But that’s only part of the story.
🧪 Muscles Release Chemical Messengers
When muscles contract, they release special proteins called myokines.
Think of myokines as text messages sent from your muscles to other organs.
These messages can travel to:
- 🧠 Brain
- 🍔 Fat tissue
- 🍬 Pancreas
- 🧬 Liver
- 🦴 Bones
📡 What Are Myokines?
Myokines = proteins released by working muscles
They can:
- Act locally in the muscle
- Affect nearby tissues
- Travel through the bloodstream to distant organs
🔁 Why Movement Matters (Not Just Motivation)
Here’s the key point from the study:
👉 Many myokines are only released when muscles contract
That means:
- No contraction = no signal
- No signal = fewer health benefits
This is why exercise improves:
- Energy levels
- Blood sugar control
- Fat metabolism
- Brain health
- Inflammation balance
🧠 The Takeaway
Exercise works because:
- Muscles communicate with your body
- Movement triggers biological signals, not just willpower
- Your workout is literally medicine created by muscle contraction
💬 Bottom line:
Exercise isn’t about being motivated. It's about understanding what movement does inside your body.
