UMI | Snowboarder / Self-Studying Movement Analyst

The more I rode, the more my right thigh burned out.

I thought it was a strength issue.
I thought it was a technique problem.

I took lessons.
Filmed myself.
Forced my weight onto the front foot.

Still, something felt off.

I was wrong.

It wasn’t about technique.

My movement was misaligned at a structural level.


Now I use my own body as a test subject, trying to understand that misalignment.

4 Stance Theory.
STANCER measurements.
Hip mobility analysis.

What emerged was a profile that works against ideal carving mechanics:

B2 type / right-side dominant / lateral loading bias


Why can’t I load my left side?
Why does my rotation stop?


This blog is a research log.

A process of connecting scattered discomfort into a single line of understanding.

I’m not here to impose a theory.

If you’ve ever felt like something is “off,”
this might give you a different way to look at it.


You’re not broken.
You’re just biased.
