Frequently asked questions

What is muscle definition?
Muscle definition is the visible detail and separation between muscles that shows when the layer of fat over them is low; it's also called muscularity.
How do you get more muscle definition?
Definition comes mainly from lowering body fat through diet and cardio while keeping muscle, so the underlying shape and separation become visible.
Why can't I see my definition even though I'm strong?
You likely have muscle but too much body fat covering it; definition only shows once body fat drops low enough to reveal the muscle underneath.
