I don't have a clue. Unflexed I have a six pack visible though, I have seen pictures of people with that up to 16% BF I also seen people with that around 12%. I drink everyday, about a year ago I was under 8% because I didn't drink at all. I still wasn't peaking due to not working out.
six pack visible at 16% bf? I think you may have misjudged that person's bf%
Was a picture on BB.com. Maybe he was really shredded, no homo, then went on a bulk, making his six pack a lot bigger than normal.
Not how it works, but all those charts and pictures aren't exactly accurate.
Depends how a person stores fat, how visible their abs are and generally who you ask.
Visible abs on a empty stomach can be 15%, bone dry dehyrdated af shredded can be 5-8%. Need a picture to really tell.
The only absolutes are if you have visible abs all day, even after high carbs and lots of sodium and retaining water like a camel you're 6-12%. Same situation but striations on shoulders is safe to assume 10%bf max.
If you look into a mirror and a manatee stares back it's safe to assume you're over 25%bf.
I was probably between 6-12 because I drank near 15 bottles a day. I do stay away from sodium because of loss of bone mass.
