Weekly training review

A weekly review is the most common thing athletes ask an AI assistant for. This recipe makes the assistant pull load, volume, intensity distribution, and form in a fixed order, then deliver a coached summary with a concrete next step — without inventing anything.

When to use this

• Every Sunday or Monday, to close out a training week.
• After a heavy block, to see whether form is trending into a hole.
• Any time you want a load-and-intensity readout instead of eyeballing charts.

The recipe

Copy this, set the window, and send it as one message.

You are my endurance coach. Using only my intervals.icu data through icuvisor,
review my training for the last 14 days.

Pull, in this order:
1. My athlete profile, so every number uses my units, zones, and thresholds.
2. My fitness trend (CTL, ATL, TSB) across the window.
3. My training-load and volume summary for the window.
4. The list of activities in the window.
5. My time-in-zone and training-load balance for the window.

Then give me:
- A three-sentence summary of the period: load, volume, intensity mix.
- The two most significant sessions and why they mattered.
- Recovery risk: is form (TSB) trending into a hole?
- One specific thing to do in the next 48 hours.

Rules: do not invent metrics that aren't available — if something is missing,
say so. Keep subjective scales labeled correctly (sleep quality 1-4, feel 1-5).
Tell me which icuvisor tool each key number came from.

What icuvisor does

The assistant should call, in roughly this order:

analyze_trend may also be used to state whether load is meaningfully rising or falling.

A good answer looks like

Last 14 days. You completed 9 sessions for a load of 612 (get_training_summary), up about 11% on the prior fortnight — a normal build-week ramp (analyze_trend). 8h 40m total, mostly riding. Your intensity split was 78% low / 9% moderate / 13% high — pyramidal, leaning polarized (compute_zone_time, compute_load_balance).

Notable sessions. Tuesday’s 5x5 min VO2 ride (load 95) and Saturday’s 3h 20m endurance ride (load 168) carried most of the work.

Recovery risk. CTL 62 → 66, ATL 71, TSB -9 and falling (get_fitness). You are productively fatigued, not buried — but a second hard day soon would dig a hole.

Next 48 hours. Keep tomorrow easy (Z1-Z2, under 60 min) so TSB stabilizes before your next quality session.

Every number is tagged with the tool it came from, and nothing is asserted that the tools did not return.

Variations

• Monthly review: change the window to “the last 28 days” and ask for the polarization trend week-over-week.
• Compare two periods: “Compare the last 14 days with the 14 days before — what changed in load and intensity?”
• Sport-specific: add “Only consider rides” or “Only consider runs” to scope the summary.

Why this prompt works

• Numbered tool order stops the assistant from skipping the profile and misreading zones.
• “Do not invent metrics that aren’t available” is the line that cuts hallucinated zone percentages — the most-reported failure with AI training analysis.
• “Tell me which tool each number came from” makes the answer auditable, so you can spot a wrong number instead of trusting a fluent paragraph.
