The Tech and Science Behind Iron Buddy

The Science and AI that power your performance

It's not magic — it's multivariable analysis of biometric data. We'll explain how Iron Buddy turns your Strava activities into actionable feedback.

1. Data extraction and normalization

The process starts when you sync your activity. We don't just read the distance; we extract the full file .FIT or .TCX through the Strava API.

  • ¿Qué analizamos? Time series of heart rate (HR), power (W), cadence, elevation and speed variability.
  • Normalización: We adjust the data based on your profile (age, weight, sex and configured effort zones) so the analysis is 100% individual.

2. The load and fatigue algorithm (effort modeling)

We use models based on the Training Impulse (TRIMP) y la relación entre la Carga Crónica (Fitness) y la Carga Aguda (Fatiga).

Our AI doesn't just look at how much you ran today — it looks at how that effort impacts your last 28-day window.

  • Detección de sobrecarga: We identify deviations in the power/heart rate ratio (aerobic efficiency). If your HR is high for a low power output, Iron Buddy knows you're tired before you do.

3. Natural Language Processing (NLP)

This is where the "buddy chat" magic happens. Once the numerical data is processed, our Natural Language Generation engine turns the metrics into words.

  • Contextualización: The algorithm understands whether you did an interval workout, a long run or a regenerative jog, and adapts the tone and advice based on the detected intensity.

4. Machine Learning for recovery

Iron Buddy learns from your history. If we detect that after certain levels of TSS (Training Stress Score) your performance drops in the next 48 hours, the system prioritizes active recovery or full rest advice.

Why trust Iron Buddy?

Unlike generic algorithms, our AI has been trained on thousands of hours of endurance data. We aim for the Eficiencia Mecánica y la Salud Metabólica. We don't want you to train more — we want you to train better.
