FizryVO2 is a free app that provides a quick, convenient way to estimate VO2 max. It was designed by experienced trainers and martial artists who tried to make it simple to use, so that you can use it while you are actually working with a client. Apps that are difficult to navigate, or take too much attention away from the client aren’t helpful and aren’t going to get used that much. FizryVO2 is streamlined, with simple clear, user interfaces.
Not all tests are appropriate for all individuals; for example clients with knee or hip pain are poor candidates for the step test, or the one-mile jog. The resting heart rate method of evaluation might be a useful alternative to get a base-line estimate. Because clients and available equipment vary FizryVO2 includes calculators for four separate methods and instructions for performing each of them. It also includes a convenient stopwatch and a kilogram to pounds converter so that you don’t have to fumble around changing apps while testing a client.
