What 3% Body Fat Looks Like
Competition bodybuilder at peak. Full six-pack with razor-sharp cuts. Prominent veins across arms, shoulders, and lower abs. Paper-thin skin. Gaunt face with hollow cheeks.
Competitive bodybuilders like Helmut Strebl and Andreas Munzer have been documented in the 3-5% range at competition. These levels are maintained for hours to days, never sustained long-term.
