• Charge for individual tests. Athletes seeking out testing will normally pay an average of $150 for VO2 Max fitness tests, and $40 for resting tests (measuring their daily calorie burn).
  • Upgrade programs. Provide an upgraded training package that includes training regimens shaped by metabolic testing, increasing your monthly income from training programs. 
  • Re-test clients regularly. KORR customers report that more than 50% of their customers return regularly for re-testing. More testing leads to more revenue (and more satisfied customers).

what is vo2 max?

A VO2 Max Test is a 10- to 15-minute test that shows individuals – from the sedentary to the elite athlete – personalized information about heart-rate zones, calorie burn and more. Results can be uploaded to the CardioCoach app for application in personalized workouts, or used by trainers to shape goals and training regimens for optimal client results.

In addition to VO2 Max testing, the CardioCoach by KORR can also test Resting Metabolic Rate, or RMR.  Use this information to guide clients in calorie counting as you help them achieve their weight-loss goals!
