Perceived Effort
You can determine if your estimated MHR is correct by comparing Myzone effort zones to your rate of perceived exertion (RPE) during cardiorespiratory exercise.
Note: RPE doesn’t always match up with exercise intensity during strength training. Our Max HR is based on how hard the heart is working during cardiovascular exercise. We do not have a separate Max Heart Rate for strength training.
Try it out!
Rate of perceived exertion uses a scale of 1-10 (1 = lightest intensity, 10 = maximal intensity). For example:
- You should feel like you’re at about a 6 on the RPE scale when you’re exercising in the BLUE zone (60-69% of estimated MHR)
- You should feel like you’re at about a 9 or 10 on the RPE scale when you’re in the RED zone (90%+ of estimated MHR).
If you’re a new Myzone user, pay attention to your Myzone effort zones and your RPE during your first few cardiorespiratory workouts. Do they align closely? Is there an obvious discrepancy?
Can I change my Max HR in the app?
Myzone is the only wearable on the market that automatically recalibrates your max heart rate if it sees that you are capable of sustaining higher peak rates. While we have built in algorithms to override false readings, if you feel one got through, our support team is happy to review this with you and make any necessary adjustments.
Usually, an incorrect reading looks like a spike of red activity that does not fit within the rest of the workout--these stick out and are easy to spot.
If you see a great deal of red zone activity and the workout flows as usual, chances are you do need a bump. This is ultimately a good thing--we can't truly measure and improve without an accurate starting point!
