I got down to 6.3% bodyfat and I can say its a struggle and looking at your pic, I would say your not at 7 % no offense. But when your at a lower single digit number your should not have to flex your abs to see them. The key to low bodyfat and abs, is little to no sugar in the diet. In my opinion, if you want to see your abs without posing, shoot for 20g of sugar of less a day. Remember a can of soda is 41g of sugar, so it takes alot of strict dieting.
