Five questions before you push through fatigue:
1. What was this session meant to achieve?
2. How does the effort compare with normal?
3. Is this one difficult day or a changing pattern?
4. What has changed outside training?
5. What does the rest of the week need?
One score rarely settles the decision. Look at the direction across several days and add context.
Depending on the answers, the useful adjustment may be lower intensity, shorter duration, different timing or complete rest. Match the change to the reason, then reassess.
Pain, illness or concerning symptoms require a separate health decision. This checklist should not be used to justify pushing through them.
Today's email explains how I use these questions to adjust a training week without abandoning its purpose.
