For men, if you're around six to 17 percent body fat, your abs should be noticeably visible. For women, the range is 14 to 24 percent body fat. Definition will start to show on the higher end (17 percent for men, 24 percent for women), and your abs will become more sculpted as that number lowers.
What % Body Fat Percentage is Needed to Reveal Your Abs? Having a six pack requires a leaner physique - typically within the athletic range. The body fat percentage needed to see your pack of abdominal muscles falls somewhere around 14 to 20% for women and 6 to 13% for men.
At around 15 per cent body fat, men will tend to start seeing muscular shape and definition, while noticing changes in body composition and fat stores. Your arms and shoulders are more vascular too. You're now on-track for a six-pack.
Men who have less than 6 percent body fat and women with less than 16 percent body fat are considered too low.
Your timeline to a six-pack depends on the body fat percentage you're starting with. A good rule of thumb (and a safe one) is to aim to lose 1 to 2 percent of body fat per month. So, unveiling your abs can take anywhere from 3 months to 2 years. It really does vary.

If you regularly perform abs workouts and back that up by eating a healthy diet, your upper abs will quickly start to emerge. Unfortunately the rest of your abs won't simply follow. The upper abs are the first to show and the easiest to work, because most of the best-known abs exercises target them specifically.
You have too much body fat.
The single most important aspect when it comes to getting your abs to show is having a low body fat percentage. All humans have abdominal muscles that can be made more visible with training – but ultimately to see your abs you need to be at 10% body fat or less (18% or less for women.)
There are many people who are obese but still have well-defined abdominal muscles. This is because having "fat abs" does not mean that you do not have any abdominal muscle definition; it simply means that your ab muscles are hidden under a layer of fat.

Then, even rarer than the 2-pack is a total of 10 or even 12 abdominal muscles, meaning 5 or 6 bands of the connective fascia. These statistics are the same for men as for women, with the most common being 6-pack for everyone.
Your Abdominal Muscles Aren't Thick Enough

Men and women need different amounts of fat. For a man, 2–5% fat is essential, 2–24% fat is considered healthy, and more than 25% classifies as obesity. For a woman, 10–13% fat is essential, 10–31% fat is healthy, and more than 32% classifies as obesity.

Men should have 8% to 19%. For people 40 to 59, women should fall between 23% to 33% and men should fall around 11% to 21%.
Always bulk if you are close to or below 8% or 17% body fat for men or women, respectively. Always cut if you are close to or above 18% or 28% body fat for men or women, respectively.
