Building Arveno
5 things building a fitness AI taught me about my own body
The short version
- My recovery and my ego disagreed — often
- Symmetry was the thing I never trained
- The scale was my least useful number
- Consistency beat intensity every week
- One clear call changed more than any plan
My recovery and my ego disagreed — often
The days I most wanted to push were usually the days the data said back off. Building the coach meant learning to trust it over the ego.
Symmetry was the thing I never trained
I'd tracked weight for years and never once measured left vs right. My own scan flagged an imbalance I'd been feeding for months.
The scale was my least useful number
Watching my own data, weight bounced with water and meals while the signals that actually mattered moved quietly underneath.
Consistency beat intensity every week
The weeks that moved the needle weren't the heroic ones. They were the boring, complete ones. The data was blunt about it.
One clear call changed more than any plan
A perfect plan I second-guessed daily lost to a simple 'today: recover'. Removing the decision was the actual product.
