Body fat percentage is a key indicator of fitness and can determine whether your abs are visible:
| Category | Men | Women | Abs Visibility |
|---|---|---|---|
| Essential Fat | 2-5% | 10-13% | Extremely defined (not sustainable long-term) |
| Athletes | 6-13% | 14-20% | Visible six-pack, very defined |
| Fitness | 14-17% | 21-24% | Visible abs, especially with flexing |
| Average | 18-24% | 25-31% | Abs not clearly visible |
| Overweight | 25%+ | 32%+ | Not visible |
Men typically need to be below 15% body fat for abs to become visible, with optimal definition around 10-12%.
Women typically need to be below 22% body fat for abs to become visible, with optimal definition around 16-19%.
Neck: Measure around the middle of your neck.
Waist: Measure around your waist at the level of your belly button.
Hip: Women only - measure around the widest part of your hips.
For best results, take measurements first thing in the morning before eating or drinking. Use a flexible measuring tape and ensure it's snug but not tight.
