Loads
How much strain your last week actually cost you.
Recovery is a debt
Every session is a withdrawal; every good night is a deposit. Load is the running total — and it's the number that predicts injury better than anything else.
What we count
volume time in each zone intensity weighted by zone rest sleep + HRV recovery output daily + weekly load
Why it matters
Load that climbs too fast is how every overtraining story starts. We chart it so you can see the wall coming.
