Train Hard Fed, Rest Fasted Rule
Train hard fed, rest fasted means quality sessions get pre-fuel; easy or rest-day movement may stay fasted—protects performance while keeping optional fasted cardio.
The train hard fed, rest fasted rule fuels intervals, heavy lifts, and long quality sessions with prior carbs and protein while reserving optional fasted easy cardio or rest-day walks for fat-oxidation experiments. It prevents the common mistake of fasted HIIT or max squats inside a long daily fast.
Deload weeks may relax the rule slightly.
Common questions
-
Does this rule forbid all fasted training?
No—it limits fasted work to easy intensity. You can still do morning zone 2 fasted if energy and sleep are solid; just do not stack it with a fasted lifting PR day.
