Your Maximum Heart Rate, or MaxHR, is an important metric that FITIV uses to calculate your workout intensity and heart rate training zones. It is important to have an accurate MaxHR value listed in your FITIV settings to ensure that your workouts are recorded and displayed as accurately as possible.
You can adjust your MaxHR or use an alternate calculation under MORE>HEART RATE INFO.
Generally Maximum heart rate is calculated according to your age, but you can input a specific value if you have a different MaxHR value that you have found as the result of fitness testing.
By default FITIV uses the following formula to determine your MaxHR:
MHR = 220 - age
If you find that this formula is too low, or you are a highly trained athlete, you may prefer to switch to Formula B, which is:
MHR = 210 - (0.5 * age)
If neither of these values seems right you can input a new MaxHR as desired. If you find that your MaxHR for individual workouts often surpasses the MaxHR value calculated try adjusting it to be a bit higher. If you find that you never come close to your calculated MaxHR you should try lowering the number slightly.
