Hold your pace. It's a long race.

Whether you’re running a 5K or an ultramarathon, cycling or swimming, going at a pace that is optimal, and yet sustainable for the entire distance, is the key to a great performance. But determining this golden pace can be difficult in varying climates and conditions. Frontier X helps you find your optimal zone by alerting you with a gentle buzz when you cross your sustainable pace.

Most wearables measure Heart Rate, Speed and Distance. While these metrics tell you what you are doing, they don't tell you how your body is doing. They are unreliable indicators of the Effort that your body is experiencing. Heart rate is easily affected by psychological stress and caffeine intake, while Speed based on GPS changes with wind resistance or inclination. Frontier X measures true Effort based on Breathing Rate, which is relatively robust against these external factors.

Work your heart. Don’t wear it down.

The only muscle in your body that never stops working, is your heart. It contracts and expands tirelessly about 100,000 times a day. But when you’re working out too hard for too long, the heart can be deprived of Oxygen, which can overstrain your heart and cause long-term damage. Frontier X helps you fearlessly enjoy endurance sports or workouts by warning you with a double buzz if your Cardiac strain crosses the recommended limit. Frontier X records your ECG for the entire workout, and monitors Cardiac Strain by measuring the Oxygen demand-supply imbalance in your heart while your work out. It alerts you if your Strain increases and you stray too close to the low Oxygen zone. The device has research-backed preset limits; which you can also customise.

Break barriers. Without breakdowns.

Running, swimming, cycling, boxing - you engage in different activities through the week. These activities have different durations and vary in intensity. So, how do you measure your total Training Load across a week? Frontier X gives you an objective, activity-agnostic measure of your internal training load.

Research has shown that Breathing Rate (not Heart Rate or Pace) is best correlated with your Effort. Frontier X tracks your Training Load using breathing rate as the base metric of physical effort and indicates the amount that your body can take each week. With this input, you can monitor and adjust your workout regimen to train right without risking injury.

Free your mind. Train distraction-free.

Pace, distance, cadence, vertical oscillation, GCT - there is an endless list of numbers you can worry about. Or you can just tune into your body and enjoy doing what you love while Frontier X takes care of you. It measures what matters and gives you tactile, distraction-free alerts if you cross your pre-defined thresholds.

Frontier X is intelligently designed to run independently of a smartwatch or smartphone while you workout. It gives you a discreet single buzz when you cross your sustainable pace and a double buzz when you overstrain yourself. You can check the workout data on the Frontier X companion app.
