Every week, Paceline tracks a handful of signals from your connected device.
Together they show not just that you moved — but how much, how hard, and how consistently.
Elevated Heart Rate minutes (eHR)
Your headline number. Any minute your heart rate is elevated to moderate intensity or above counts — a brisk walk, a bike ride, a dance class. It doesn’t matter what you do, only that your heart is working.
The number that earns your Streak
Hit about 150 eHR minutes in a week and earn your Streak. That target comes from major health guidelines for weekly moderate-to-vigorous activity.
Heart Rate Zones
A heart rate zone is a range of beats per minute, expressed as a percentage of your maximum heart rate (the fastest your heart can safely beat). As you move harder, you climb from one zone to the next.
A common starting estimate for max heart rate is 220 minus your age. Your true max is personal, and most devices refine it over time.
Different zones, different gains
Lower zones build endurance and aid recovery; higher zones build speed and peak fitness. The mix is what matters.
The sweet spot for health
Major health guidelines target moderate-to-vigorous activity — roughly Zone 2 and up. That is where the heart-health benefit lives.
Train smarter, not just harder
Zones keep easy days easy and hard days hard — progress without burning out.
A simple way in: warm up through Zones 1–2, spend most of your time in Zone 2–3, and add short pushes into Zone 4–5 to build fitness — then ease back down to recover.

The simplest signal there is — counted from the motion of your wrist or phone. Steps don’t ask how hard you worked; they capture how much you move through your day, which matters on its own.
Floors
Climbing counts extra. Devices with a barometric altimeter sense changes in air pressure as you gain elevation — one floor is typically about 10 feet (3 meters) of climb. Stairs, hills, and hikes all register.
Distance
How far you traveled under your own power. Outdoors it comes from GPS; indoors your device estimates it from your stride and pace. Distance gives your walks, runs, and rides a size — and a way to see them grow.
Why your numbers differ across devices
If your device and Paceline show slightly different numbers for the same week, that’s expected. Every metric here is calculated, not handed down, and every device makes its own assumptions:
How they sense movement
Wrist sensors, phone accelerometers, chest straps, altimeters, and GPS all measure differently — and each has blind spots.
What they assume about you
Max heart rate, stride length, sensitivity thresholds — different assumptions shift every number.
How they define a unit
Apple, Garmin, Fitbit and Whoop each use their own formula for a “zone minute,” a step, or a floor.
How often they sample
Brief spikes near a boundary can land on either side.
