HR zones in KULG

Written By KULG App

Last updated 3 months ago

KULG’s philosophy is largely based on the simple heart rate metric, which is easily accessible and still a highly valuable and objective estimate of your aerobic fitness, overall running progress, and recovery. Here’s what you can see and do in KULG concerning the HR zones now.

Editing your HR zones

  • You can see and edit your HR zones under Settings » HR zones

  • As we bring over your workout history, we’re automatically taking the maximum HR from the previous year as your max HR, and the 5 zones are calculated based on that max HR number

  • You can update your maximum HR and recalculate the HR zones by clicking on “Calculate and save” button.

  • You can also manually set your HR zones if you need more customization by selecting “Edit zones manually”, making the edits, and clicking on “Save HR zones”

    • NB! Please ensure that the start of the next HR zone does not overlap the end of the previous one, and that there are no gaps between zones. For example, if Zone 1 ends at 124 bpm, Zone 2 should start at 125 bpm (not 124 or 126). Please also ensure that all 5 zones are filled.

Which HR zone model is KULG using?

KULG is using a 5-zone model that calculates your training zones as percentages of your maximum heart rate:

  • Zone 1 (very easy) - 50-60% of your max HR

  • Zone 2 (easy) - 60-70% of your max HR

  • Zone 3 (moderate) - 70-80% of your max HR

  • Zone 4 (hard) - 80-90% of your max HR

  • Zone 5 (very hard) - 90-100% of your max HR

How can I use the HR zone info?

Knowing your HR zones gives you a better understanding of how hard you are training. In Activities, you can also:

  • See the HR zone for each activity based on your average HR

  • Easily compare the average HR of similar types of runs when filtering by activity type
