The CardioCoach delivers simple and accurate fitness testing based on oxygen consumption. This data can be used as the foundation for customized exercise programs that truly meet the needs of the individual. It is so simple to use that any of your current employees can perform a VO₂ Max test. It is affordable, allowing even small gyms, personal trainers and educators to own state of the art VO₂ Max test equipment. To download a CardioCoach product brochure, click here.
Why Choose CardioCoach?
Mixing chamber Technology
A mixing chamber is considered the “Gold Standard” for VO₂ Max measurements.In the past, this system has been complicated and expensive, making it only practical to train professional athletes and for use in research departments. KORR’s advancements in technology make this equipment feasible for gym owners and trainers at any level of expertise to own.
Adjustments for barometric pressure, temperature, and humidity are key to an accurate VO₂ measurement. The CardioCoach measures these parameters during each routine calibration cycle, then automatically compensates to standard (STPD) conditions.
The CardioCoach has a simple user interface with wireless connections. No training or certification is necessary.
CardioCoach uses Anaerobic Threshold and VO2 Max results to define workouts zones unique to each client. These results can be uploaded to the CardioCoach app to guide your client through workouts for cardio-strengthening, endurance, weight loss or other goals custom designed by you.
Routine replacement of the oxygen sensor is required but can be performed on site by your own staff.
The CardioCoach has been independently validated at the University of Southern California and Oregon State University. To view those results, click here.
KORR offers 3 different CardioCoach models
Multiple options allow you to select the model that best meets your needs.
The CardioCoach is all about simplicity. Simplicity of operation means any trainer can learn to perform a test in minutes. Simplicity of the reports means customers receive easy to understand results that define unique workout zones for endurance, weight loss, and cardio strengthening.
The CardioCoach PLUS combines the features of VO₂ fitness testing with Resting Metabolic Rate (RMR) Measurement. An RMR measurement uses oxygen consumed at rest to determine a person’s caloric requirements for weight loss or maintenance. Facilities that offer nutritional counseling can add this very valuable assessment tool for only a slight increase in cost.
The CardioCoach MAX includes the additional measurement of CO2. The added hardware allows you to see Respiratory Exchange Rate (RER) during exercise. This information will show your client at what heart rate they are burning fat most effectively and allow them to monitor fat burn in real time when utilizing the CardioCoach app.
VO₂ Pretest Requirements
Complete the Exercise Readiness Questionnaire (ERQ) or Participate Activity Readiness Questionnaire (PARQ).
Dress in comfortable exercise attire.
Refrain from exercise or endurance training for 24-hours prior to test.
Avoid food, tobacco, alcohol, and caffeine for at least 3 hours before testing.
Continue medications as usual.
Exercise warm-up per usual routine.
Conduct a Test
The client puts on a mask and heart rate strap. The mask is connected to the CardioCoach™ device via the VO₂ hose.
The client exercises on a stationary device such as a bicycle, treadmill, or stair stepper. They gradually increase their intensity over a period of 6 to 20 minutes until the CardioCoach™ indicates that the anaerobic threshold has been detected. At this point, the client may stop exercising and begin a cool down phase.
The CardioCoach™ compiles the data, analyzes the results and will print a fitness profile in a simple, insightful report where exercise zones are identified. Trainers can further customize their client’s workout by uploading the results to the CardioCoach app.

A complete VO₂ fitness test can give trainers the tools to set realistic goals and assess improvement
Many people are inefficient exercisers – they have no understanding of what heart rate, intensity or duration would best help them reach their specific goals such as fat burning, endurance training, or cardio conditioning.
An initial VO₂ Max test can clarify the precise target heart rates that will enable each individual to exercise more effectively, with less fatigue and fewer injuries. Periodic retesting provides motivating feedback as the fitness program progresses. Studies show that previously sedentary people training at 75% of aerobic power for 30 minutes, 3 times a week over 6 months increase VO₂ Max an average of 15-20%.
Anaerobic Threshold (AT)
Even though extensive training can sometimes cause an athlete to reach a plateau in VO₂ Max, he can still use his VO₂ Max test results to make further improvements in performance. This is accomplished as he pushes to increase anaerobic threshold (AT) and maintain that threshold for longer periods of time. This enhances both endurance and cardiovascular performance.
A VO₂ Max test determines the number of calories burned during every level of exercise. Additionally, CardioCoach PLUS and CardioCoachCO₂ measure a Resting Metabolic Rate. This is a scientific measurement of how many calories a person is burning during a day, a vital piece of information when designing a weight loss regimen.

CardioCoach™, and all other KORR™ measurement devices, auto calibrate. It is important to note that KORR devices calibrate to temperature, humidity, and barometric pressure, making them both simple to operate and highly accurate.
The CardioCoach will need the oxygen sensor replaced every 20 to 24 months.Units purchased after August 2019 will be able to perform this service in their own facility by ordering the sensor from KORR directly.Older CardioCoach units are required to be sent to a KORR certified service center for replacement of the Oxygen sensor and re-calibration. Currently, service centers are located in Salt Lake City Utah USA, Sydney Australia, and Athens Greece.
The CardioCoach™ measures oxygen consumption only, providing measurements of Peak VO₂, aerobic threshold, anaerobic threshold, and VO₂ Max. For those desiring RER (information about fats versus carbs burned during exercise), a CO₂ measurement is available with the CardioCoach™ MAX unit.
As a trainer for professional basketball athletes I’ve been using the CardioCoach for over 10 years. There are other pieces of VO2 test equipment out there, but through my research I’ve determined the CardioCoach to be the most reliable and valid. It is also very user friendly; for the most part all you have to do is hit start and it runs itself!

I have used KORR products since 2003. Over the last 10 years I have always recommend (KORR) equipment if someone is looking for an accurate, portable, and easy to use metabolic cart.

CardioCoach gives me a precise and somewhat unique training method. My clients now have what was once reserved for the very best elite athletes, and consequently, an edge on their competition.
Michael BriantBodyology Exercise Science, Columnist “Australian Triathlete Magazine”
(CardioCoach) solved the issue of how to attract those who are not solely interested in a gym membership into the facility. It provides us an opportunity to show how you can improve your results from exercising. Additionally, members love it. It both verifies what they’re doing is working and shows them an opportunity to improve. There is something about seeing your own personal results in black and white, versus guessing what is going on within your body.
Gabriel BradleyGeneral Manager South Reno Athletic Club
Since I have coupled my unique Total Being Programs with VO2 Max testing, my clients have experienced remarkable results. Using KORR equipment and Total Being Programs takes the guess work out of personal training.
Metabolic testing with the KORR CardioCoach can be a phenomenal addition to your training department and service for your members. My staff and I have brought a great addition to the club and to our members by offering a service that is traditionally only offered in elite athlete testing centers or universities.
