Before hard training of the same muscles again.
Moderate load — allow at least a day before loading the same muscles hard again. General physiology, not personal advice — sleep, nutrition, age and training status all shift the window.

What it means
- Adaptation continues after a hard session — reloading too soon undercuts it.
Limitations
- General physiology, not personal advice — sleep, nutrition, age and training status all shift the window.
