Analyze Body Fat🎯 Understanding Your Body Type
Your somatotype determines how your body responds to training, nutrition, and lifestyle factors. Understanding your genetic blueprint helps optimize your fitness approach for better results.
Genetic Foundation
Your body type is largely determined by genetics, influencing bone structure, muscle fiber composition, and metabolic rate. While you can't change your basic somatotype, you can optimize your approach based on your natural tendencies.
Metabolic Differences
Each body type has distinct metabolic characteristics that affect how you process food, store fat, and build muscle. Understanding these differences is key to creating an effective nutrition strategy.
Training Response
Your somatotype influences how you respond to different training styles, recovery needs, and exercise selection. Tailoring your workout to your body type maximizes results and prevents overtraining.

Measurement Guide
Wrist Circumference
Measure around the narrowest part of your wrist, just below the bony prominence. This measurement is crucial for determining bone structure.
Normal ranges:
• Men: 15-20 cm (6-8 inches)
• Women: 13-17 cm (5-6.5 inches)
• Men: 15-20 cm (6-8 inches)
• Women: 13-17 cm (5-6.5 inches)
Shoulder Width
Measure the distance between the outer edges of your shoulders at the widest point. Stand naturally and have someone help measure.
Typical ranges:
• Men: 38-48 cm (15-19 inches)
• Women: 35-42 cm (14-16.5 inches)
• Men: 38-48 cm (15-19 inches)
• Women: 35-42 cm (14-16.5 inches)
Hip Circumference
Measure around the widest part of your hips/buttocks. Keep the tape measure parallel to the ground.
Health note: Hip measurement helps determine body fat distribution patterns and metabolic health indicators.
The Science
Somatotyping was developed by psychologist William Sheldon in the 1940s. Modern fitness science uses anthropometric measurements to classify body types based on:
- Bone Structure: Joint size and frame dimensions
- Muscle Mass: Natural muscular development
- Fat Distribution: Where and how easily fat is stored
- Metabolic Rate: How quickly calories are burned
Accuracy Note: Most people are a combination of types rather than purely one category. Our calculator provides percentages for each type.
