What is BFP (Body Fat Percentage)?

BFP stands for Body Fat Percentage - the proportion of your total body weight composed of fat tissue. It is a more accurate health indicator than weight or BMI alone.

How accurate is the Navy Method body fat calculator?

The U.S. Navy circumference method has an accuracy of ±3.5%, comparable to a $100 DEXA scan. It is much more reliable than BIA body fat scales which can vary ±10% based on hydration.

How do I calculate body fat percentage at home?

Use our free calculator with either the BMI-based formula (only needs height, weight, age, gender) or the U.S. Navy method (also requires neck, waist, and hip measurements with a tape measure).

What is a healthy body fat percentage?

For men, a healthy body fat percentage is typically 14-17% (fitness range). For women, a healthy range is 21-24%. Athletes tend to be lower: 6-13% for men, 14-20% for women.

How is BFP different from BMI?

BMI only considers height and weight, so it cannot distinguish between muscle and fat. BFP directly measures body composition. A muscular person may have a high BMI but a healthy BFP, while a skinny-fat person may have a normal BMI but a high BFP.

Strength Standards: How Strong Are You? Squat, Bench & Deadlift Percentiles by Body Weight

How Strong Are You for Your Size?

A 200 lb bench press means very different things depending on your body weight. For a 150 lb person, it's elite. For a 250 lb person, it's intermediate. Strength relative to body weight is what matters.

Our free Strength Standards tool compares your lift numbers to population standards based on your body weight — and even adjusts for body fat percentage.

The Four Strength Levels

Level	Description	Squat	Bench	Deadlift
Novice	New to lifting, still learning form	Bodyweight	0.6x BW	1.1x BW
Intermediate	Consistent training 1-2 years	1.3x BW	0.9x BW	1.6x BW
Advanced	Serious training 3-5 years	1.8x BW	1.3x BW	2.2x BW
Elite	Competitive powerlifter level	2.2x BW	1.5x BW	2.8x BW

Approximate multipliers for a typical male lifter. Standards vary by weight class.

Body Fat Matters for Strength Standards

Someone at 15% body fat and 80kg carries more muscle than someone at 30% body fat and 80kg. More muscle = more strength potential. That's why our tool adjusts standards: if you have a high BFP for your weight, your strength-to-weight ratio expectations are slightly lower. If you're very lean, they're slightly higher.

How to Use Strength Standards

Test your 1-rep max (or calculate it from a 3-5 rep max)
Enter your body weight and body fat % in the Strength Standards tool
See how each lift ranks: Novice → Intermediate → Advanced → Elite
Set your next goal: move up one level in your weakest lift
