16-18 percent : You look like you hold no excess weight when fully clothed.
15 percent : Starting to look good naked.
13 percent : You won’t be compromising performance due to excess body fat.

10 percent : Somebody’s resembling the Michelangelo statue…
5-8 percent : Ripped to bits; the optimal level at which all top level, in-form male endurance athletes perform.
