Your heart rate variability averaged 34ms this week, down from 44ms last week. That's a significant drop.
Possible cause: you trained 6 days straight with no rest day. Your body is accumulating fatigue faster than it can recover.
This week's focus: Take two full rest days. Your HRV typically rebounds within 48 hours when you do.
Works with the Apple Watch, iPhone, or any device you already own. Corro reads from Apple Health — nothing else to buy or wear.
Corro analyzes up to 10 years of health data. Not just today — your entire training history, sleep patterns, and recovery trends.
Ask a question in plain English. Get a specific answer with real numbers — not a chart you have to interpret yourself.
