-5 bpmAcross the filtered period, average heart rate moved from 141 to 136 bpm — a sign of improving aerobic fitness.
Monthly average (solid teal) and peak (dashed orange) heart rate, with shaded bands marking training zones Z1–Z5 based on age-predicted max HR
For each activity type: whiskers show min/max HR, the orange box spans Q1–Q3 (middle 50% of efforts), centre marks the median — wider boxes mean more variable intensity
Count of activities falling into each 10-bpm average-HR bucket, coloured by training zone (Z1 easy → Z5 max effort) relative to age-predicted max
Each dot is one activity — X-axis: duration in minutes, Y-axis: average HR, colour indicates sport. Useful for spotting long efforts sustained at high intensity
