Why Use Calculators Before Logging
Calculator-first workflows reduce guesswork. You estimate targets first, execute with less decision fatigue, then log what actually happened. This improves consistency and makes weekly adjustments evidence-based.
- Calculate: get load, calorie, or pace targets.
- Plan: choose a range and commit for 1 to 2 weeks.
- Track: log execution and compare against plan.
