Why it matters
HRV drops after hard training are normal and expected — your heart rate variability reflects your nervous system's recovery status, and intense exercise is a stressor your body needs to recover from. What's less normal is an HRV that drops disproportionately to your training load, or that takes days longer to recover than it should. This usually means something outside the training itself is amplifying the impact — poor pre-workout nutrition, high background stress, alcohol, poor sleep, or training at the wrong time of day for your biology. Finding out which one is affecting you specifically changes how you train.
When Normal helps
Normal connects your training load to your HRV response over time. It finds whether your HRV drops are proportionate to your training, and if not, what lifestyle factors are consistently amplifying the impact and slowing your recovery.
How Normal finds it
Tell Normal about your training and connect your Apple Health data. Over four to six weeks it finds the specific pattern of what makes your post-training HRV recovery slower or faster. Most people find one or two lifestyle factors outside training that are significantly affecting their recovery speed.
