Fuel for the Work Required
Fuel for the work required adjusts daily carbs and calories to that day’s training load rather than using identical macros every day.
Fuel for the work required (FFWR) matches daily carbohydrate and calories to that day’s training load—more carbs on long or intense days, less on rest days—instead of flat macros year-round. It supports body composition and performance without chronic low-energy.
Protein stays relatively stable; carbs flex.
Common questions
-
Is FFWR the same as carb cycling?
They overlap—both flex carbs by day. FFWR explicitly ties fuel to session type and energy expenditure, not arbitrary high-low days.
