A coach asked harlen.

Why is Elena's recovery trending down?

You

Sleep tanked after April 14. Duration dropped from 7h12m to 6h47m, efficiency from 88% to 81%. Travel that week broke her routine. Load held — this is recovery debt, not overreach. Pull Tue/Thu volume. Recheck Monday.

why it pays
01

Charge more.

Adjustments backed by real data look different from memory and feel. Clients see the difference. They pay for it.

02

Keep them.

Clients quit when they stop feeling progress. Show them the data on a flat week — they remember why they're with you.

03

Your edge.

Most coaches still run on feel and spreadsheets. You're running on each client's real data. The gym down the street can't catch up.

Watches the whole roster. Tells you what changed.
