See How It Works

Sample Report

The CardioCoach® prints out results in a manner that makes it easy for you to explain results to your customers. It clearly displays key data points, as well as heart rate zones, fitness level, and recovery data. You personalize the results even more by inserting your own logo and adding recommendations.

Sample Report

A unique feature of CardioCoach® is the presentation of substrate utilization: the ratio of fats versus carbohydrates burned throughout each heart rate level during testing. This is especially helpful for weight loss or refueling. This feature is only available on the CardioCoach®MAX and the CardioCoach®PRO.

RMR Sample Printout

Most models of CardioCoach® allow you to test Resting Metabolic Rate, or the number of calories an individual burns at rest. With it, you can easily teach your client about energy balance and their metabolic health.

Make It Personal
