Readiness
Push, or rest?
HRV, resting heart rate and strain read against your own baseline, so you know what today can take.
Against your normal
Your numbers compared with your last weeks, never with an average person.
Sleep counted in
A short or broken night lowers today's readiness, as it should.
Strain counted in
Yesterday's hard session is part of today's answer.
One line of advice
Under the score, a sentence on what to do with it.
