Your Body Is Functional
Here's a tactic to get people to buy something.
Tell them there is something wrong, like a "dysfunction". Then make yourself sound smart and sell a "solution".
Your body is not dysfunctional. It is functioning exactly the way it is supposed to. Even when it is not functioning optimally.
Here's an example: Limping.
You can observe someone limping and assume they sprained an ankle, or hurt their knee. Or that they have a blister. Or are recovering from a surgery.
Are they dysfunctional? Not at all. Limping is a normal response to address the current situation. Should you limp forever? Nope.
There are plenty of things fitness and health gurus will promote as dysfunctions.
Posture
Alignment
Limp length
Shoulder height
Walking gait
What you eat
How you sleep
...
The list is endless.
Want to improve the way your body functions? Amazing. Love that for you.
But don't let someone else feed you a bullshit narrative that you are dysfunctional and that you need some product or program to be fixed.
