Personalized Heart Rate Zones are a crucial tool in planning, tracking and implementing workout routines in the Fitdigits app. The most accurate way to get custom heart rate zones is with a metabolic assessment done at a professional assessment center. However, that can be a pricy and time consuming option. A much more affordable option that also provides accurate training zones is a Fitdigits Fitness Assessment.
However, if neither of these options work for you and you are not up to taking an assessment, there are many equations to find custom heart rate zones. If you know your Max and Resting Heart Rate, you can get a wide variety of zones on the Determining Your Heart Rate Training Zones page.
Here you will find HR zones using percent of Max HR, the Karvonen method, Zoladz method, Joe Friel Running or Biking formula, and ABCC/BCF guidelines.
