The only good way to know your bf% is to go to someone skilled with using calipers and get measured. But, now I'm going to contradict myself and post a few Google pics.
This is about 10%.
Brock Lesnar here might be in the 15-20% range. Note that there is a difference between 'manboobs' and having big strong pecs.
Someone who looks like Vic Mackey from The Shield might be in the 25-30% range.
I'm just giving estimates here, and others might disagree with them. Your bodyfat % can fluctuate quite a bit before it "shows up" in your appearance, so that makes it doubly hard to gauge without getting proper measurements.
