health πͺ Low HRV flagged fitness issues, improving it helped training
The author noticed a concerningly low Heart Rate Variability (HRV) score during the brutal winter months. This was tracked using a Garmin watch, showing scores often below the 34β42 millisecond baseline in February. HRV measures the time between heartbeats and indicates nervous system balance between stress and recovery. The author focused on improving this metric, which correlated with feeling unwell and unfocused. Better HRV ultimately helped the author achieve their best training block to date. πββοΈ
