AI Endurance is a data-driven training platform. In order to maximally benefit from the training and have the program be most personalized to you, you'll want the best possible data to flow into the platform. Here's a few recommendations on how to achieve this.

Activity heart rate and heart rate variability data

• Use a chest strap heart rate monitor: Wrist based heart rate data is often highly inaccurate.
• Use a high quality heart rate monitor: We recommend the Polar H10 heart rate monitor (HRM). While other HRMs can record decent heart rate data, this is the recommended choice to record reliable high quality heart rate variability data (HRV) during your activities. HRV data during your activities gives us important information about your thresholds, as well as readiness to train and durability metrics. Always connect your HRM via Bluetooth for best HRV data quality.
• Enable HRV logging: For Garmin go to Settings -> System -> Data Recording -> Log HRV or Settings -> Physiological Metrics -> Log HRV. For Suunto HRV logging via a chest strap HRM is automatically enabled.

Overnight heart rate and heart rate variability data

With AI Endurance, you have the option to integrate overnight heart rate and HRV data into your training routine. We automatically monitor and adapt your training program via a personalized recovery based on your data. To get your overnight heart rate and HRV data into AI Endurance you have the following options:

• Oura: Simply connect your Oura account to AI Endurance and Oura's heart rate and HRV data are automatically taken into account for your recovery model. You can get $30 off an AI Endurance annual membership with an Oura ring. Buy at https://ouraring.com/aiendurance and email us to ask for a coupon code afterwards.
• Garmin: If you have a Garmin watch that records overnight HRV make sure to wear your watch during the night. When you connect your AI Endurance to 'Garmin - Import Data' make sure you are sharing Daily Health Stats as well.
• Others: currently indirectly if your HRV app connects to TrainingPeaks. You can then connect your TrainingPeaks account to AI Endurance. This requires a TrainingPeaks Premium account.

Cycling power data

• Use a consistent power source: if you are using multiple power meters and/or smart trainers, make sure their readings don't vary significantly relative to each other. If they do, try to use consistent power readings as much as possible. You can also exclude periods of say a wrongly calibrated power meter via the 'Data Exclusion' feature in the AI Endurance dashboard.
• For bike rides without power data, make sure to wear a heart rate monitor and ideally a cadence sensor so we can estimate your power from these metrics.

Run pace data

• Use a state of the art GPS watch that records accurate pace and elevation data.

Running power data

• Use a consistent power source. This could be either watch native or Stryd running power. Even more than with cycling power, we recommend you consistently use one power source. Different manufacturers have different algorithms for calculating running power so the power values can have significant offset.
