Training page - show last 7 days activity by heart rate groups
Many athletes train by heart rate. It would be great to look back on a rolling 7 day set of activities with a sum of how much time was spent at each heart rate zone by activity type (I.e running). I’d hope to see that 80% of my runs are zone 1/2 and 20% in zone 3/4/5 etc. The data should already be available and it’s quite simple maths and can be represented by a pie chart.
