The key distinction between being ripped and jacked is the balance between definition and overall size. While ripped emphasizes a lean and toned appearance with visible overall muscle separation, jacked prioritizes substantial muscle mass development. The definition is due to low body fat, which allows your muscles to be visible and defined.

A ripped body type is characterized by a pronounced visibility of muscle striations and veins, usually due to a lower body fat percentage. On the other hand, a jacked physique emphasizes greater muscle mass and overall size, often with a higher body fat percentage that still allows muscle shape to be visible.
