HEART RATE ZONES ARE JUST THE BEGINNING
The Frontier X2 is the world's first chest worn device that lets you set discreet real-time vibration alerts (buzzes), and nudges you into your zone without needing to look at a watch or phone. Set your lower and upper limits for a combination of Heart Rate, Breathing Rate, Cardiac Strain and tailor your workouts to achieve personal training goals and better heart health.
HEART RATE
BREATHING RATE
CARDIAC STRAIN
Customise your training and set personalised alerts depending on your needs. Here are 5 examples:

1. Heart Rate Training
Heart Rate zone alerts can be used to train in the optimal Heart Rate zone for aerobic or anaerobic workouts, and to train according to Heart Rate based training methods like the Maffetone Method.
Example Alert Settings:
- Get a Double Buzz if your Heart Rate is above 180 beats/min.
- Get a Single Buzz if your Heart Rate is below 150 beats/min.
**The above settings are meant to serve as examples. Threshold limits need to be personalized for each individual based on their fitness and heart health. Single alerts can be set if required and you can also disable all alerts.
2. Safe Heart Rate Training
Do your workouts reassured that you are in a zone that is not overstraining your heart. Set upper limits on Heart Rate and Cardiac Strain for a safe and healthy workout.
Example Alert Settings:
- Get a Double Buzz if Cardiac Strain is above 0.18 mV.
- Get a Single Buzz your Heart Rate is above 176 beats/min.
**The above settings are meant to serve as examples. Threshold limits need to be personalized for each individual based on their fitness and heart health. Single alerts can be set if required and you can also disable all alerts.

3. Cardiac Conditioning
Cardiac Strain in limited doses followed by recovery protects the heart, as demonstrated by cutting edge research on Ischemic Pre-conditioning. Use vibration alerts to nudge your heart into a zone that will help protect and strengthen it.
Example Alert Settings:
- Get a Double Buzz if Cardiac Strain is above 0.15 mV.
- Get a Single Buzz if your Cardiac Strain is below 0.1 mV.
**The above settings are meant to serve as examples. Threshold limits need to be personalized for each individual based on their fitness and heart health. Single alerts can be set if required and you can also disable all alerts.
4. Breathing Rate Based Training
According to several research studies, Breathing Rate is a better and more reliable measure of effort than Heart Rate. Train in the right effort zone by setting upper and lower limits on your Breathing Rate.
Example Alert Settings:
- Get a Double Buzz if your Breathing Rate is above 47 breaths/min.
- Get a Single Buzz iif your Breathing Rate is below 36 breaths/min.
**The above settings are meant to serve as examples. Threshold limits need to be personalized for each individual based on their fitness and heart health. Single alerts can be set if required and you can also disable all alerts.

5. Safe Breathing Rate Based Training
Push yourself harder, while keeping your heart safe. Set an upper limit on Breathing Rate to make sure you don’t cross your ventilatory threshold, while setting an upper limit on Cardiac Strain to make sure you don't push your heart too hard.
Example Alert Settings:
- Get a Double Buzz if your Cardiac Strain is above 0.2 mV.
- Get a Single Buzz if your Breathing Rate is above 45 breaths/min.
**The above settings are meant to serve as examples. Threshold limits need to be personalized for each individual based on their fitness and heart health. Single alerts can be set if required and you can also disable all alerts.
