TSS (Training Stress Score) is a single number combining how long and how hard a session was — 100 TSS ≈ roughly one hour at threshold effort. This is the same weekly figure as the bars in the chart above, zoomed to the last 8 weeks so the week-to-week swings (race week, rest week, a missed block) are actually readable. The line is fatigue (ATL — Acute Training Load), same intervals.icu daily-metrics feed as fitness (CTL) in the chart above. · Fatigue (ATL) · via Intervals.icu

AI is off

You switched AI off. Here's what it was doing.

Every AI thing on this page — the clone intro video and the Shorts — does one job: put real work in front of the people who should see it. I run it the way I'd run any system I'm accountable for: in production, with a human in the loop, measured against a number. The AI doesn't replace the expertise. It makes it easier to find.

  • Production-first. It runs in live environments, not demos.
  • Human-in-the-loop. AI helps the decision. It doesn't make it.
  • Measurable outcomes. Every use has a number attached, or it doesn't ship.

What it's for

That's the thesis behind Flywheel Motion: use AI to raise the visibility of the people doing real work, not to manufacture noise. Show the work, and let the evidence carry it.

Flywheel Motion is one product from We The Flywheel, the agentic-led, AI-first digital product and consulting studio I'm part of. Agents do the heavy lifting. People own the judgment.

The clone video and the Shorts you just turned off are the method, not the message. AI aimed at one job: getting the work in front of the people who can use it.
