Understanding your Target Heart Rate (THR) Zones can help you maximize the efficiency of your workouts, recover more quickly, and prevent injuries due to overtraining. Just fill in some simple information, and we'll walk you through each step of calculating your THR.
Thank you. Based on the information you provided, your estimated Maximum Heart Rate (MHR) is:

The formula we used to calculate your MHR is:
Males: MHR = 214 - (0.8 X your age)
Females: MHR = 209 - (0.7 X your age)

We used the Karvonen method to calculate your THR. Using a range of 50–85% intensity, the Karvonen formula looks like this: THR = ((HRmax − HRrest) × % intensity) + HRrest
Zone 1 THR intensity: 50% – 60% - Zone 2 THR intensity: 60% – 70% - Zone 3 THR intensity: 70% – 80% - Zone 4 THR intensity: 80% – 90% - Zone 5 THR intensity: 90% – 100%
