How Body Fat % Affects Your Goals

Body fat percentage is one of the most useful metrics for understanding your physique and planning your training. Unlike scale weight alone, it tells you about your body composition.

Why It Matters

For cutting: Knowing your starting point helps set realistic fat loss targets
For bulking: Staying too high makes future cuts harder; staying too lean limits muscle gain
For health: Both extremes (very low or very high) carry health risks
For aesthetics: Most people want visible muscle definition, which requires specific BF% ranges

About This Tool

Photo-based estimation uses AI vision to analyze your physique. It's not as accurate as DEXA scans or hydrostatic weighing, but it's free, instant, and good enough for most training decisions.

For best results: use good lighting, take a front-facing photo of your torso, and stand relaxed (not flexed or tensed).

What's Next?

Once you know your approximate body fat, you can make informed decisions about whether to cut, bulk, or maintain. Our AI can create a personalized program based on your estimate and goals.
