1. Define the decision: Start from current ability, recent training, health context and available recovery.
2. Check the controlling information: Choose the smallest repeatable dose that addresses the specific limiter.
3. Rehearse the plan: Progress one variable at a time and keep demanding sessions separated by recovery.
4. Review and adjust: Use symptoms, perceived effort and performance together; stop for concerning signs rather than forcing the schedule.
