How to estimate heart rate from RPE with your AI

Connect once, then give your agent a subjective effort score. It handles the math to find your estimated heart rate and training zones.

Short answer

How do I estimate heart rate from RPE?

Provide your agent with a score from the Borg 6-20 or CR10 scale. It calculates your estimated heart rate and maps it to specific training zones. You get clear physiological estimates based on how you feel.

The results you get.

What your agent delivers.

Once you provide an effort score, your AI produces these specific outputs.

DATA

Estimated heart rate

The AI converts your subjective score into a beats-per-minute estimate. This gives you a concrete number to track.

ZONES

Training zone mapping

Your agent identifies which intensity zone your effort falls into. You'll see exactly where your current exertion sits.

SCALES

Scale-specific math

The AI handles the different logic for Borg and CR10 scales. You don't need to know the formulas yourself.

HUMAN

Subjective validation

The AI provides the estimate, but you decide if the number feels right. You remain the final judge of your intensity.

The workflow

What your AI does when the score arrives.

The AI acts as the mathematical bridge between your feeling and your training data.

  1. Identify the scale

    Your agent checks if you provided a score for the Borg 6-20 scale or the CR10 scale.

  2. Calculate heart rate

    The AI applies the specific mathematical model required for your chosen scale to estimate your heart rate.

    convert_borg_6_20_scaleconvert_cr10_scale

  3. Determine training zones

    The agent uses the calculated heart rate to place you into standard training zones.

  4. Present the data

    The AI outputs the estimated heart rate and the corresponding zone in a readable format.

FAQ

How this task behaves.

  • 01

    Can the AI calculate my actual heart rate from a chest strap?

    No. The AI only estimates heart rate based on the subjective RPE scores you provide.

  • 02

    Does the AI work with both Borg and CR10 scales?

    Yes. It has specific tools to handle both the Borg 6-20 scale and the CR10 scale.

  • 03

    Can the AI change my training plan based on these scores?

    No. The AI only performs the conversion and mapping. You must decide how to adjust your training.

  • 04

    Can the AI save these scores directly to my fitness app?

    No. This MCP only performs the mathematical conversion. You'll need to copy the results into your app manually.

  • 05

    Will the AI delete my previous RPE scores?

    No. This MCP only processes the data you provide in the chat; it does not manage or delete your personal records.
