Your overall physique score is a weighted composite of all five categories below. It represents how your current physique compares against an idealised benchmark for your gender, age, and fitness level — not against other people.

BMI is calculated by dividing your weight (kg) by your height in metres squared: weight ÷ height². It gives a rough snapshot of whether your weight is in a healthy range for your height. It's a useful population-level tool but has a key limitation — it can't distinguish between muscle and fat, so heavily muscled people often score "overweight" even at low body fat.

The percentage of your total body weight that is fat tissue. The AI estimates this from visual cues — skin texture, visible muscle separation, waist fullness, and subcutaneous fat patterns — combined with your weight and height. Photo-based estimates carry a ±4–6% margin. For precise readings, a DEXA scan is the gold standard.

Calculated as shoulder width ÷ waist width from a front-facing silhouette. A higher ratio means broader shoulders relative to waist — the foundation of the classic athletic X-frame. The AI estimates these widths from pixel proportions in the photo.

Calculated as waist circumference ÷ hip circumference. This is one of the most clinically validated markers for cardiovascular health and metabolic risk. A lower ratio (smaller waist vs hips) is generally healthier. For aesthetics, a lower WHR in women indicates the classic hourglass shape; in men it signals a lean midsection.

The V-Taper Index measures how strongly your upper body tapers from wide shoulders down to a narrow waist — creating the iconic "V" shape. It's a composite of your shoulder-to-waist ratio and lat width visibility. Wide lats, capped deltoids, and a tight waist all contribute to a higher score. This is heavily influenced by lat development and overall upper body muscle mass.

Measures left-right balance across key muscle groups — arms, shoulders, legs, and overall silhouette width. The AI compares the visible size and shape of paired muscle groups from the photo. Perfect symmetry is extremely rare; most people have a dominant side. A score above 80 indicates excellent balance between sides. Imbalances are normal and can be corrected through unilateral training.

An overall score (0–100) representing the apparent muscle mass and development relative to your frame. It combines estimated lean mass percentage, visible muscle fullness, and how developed each major muscle group appears in the photo. A higher score means more total muscle relative to your frame size — not just definition, but overall size and density.

A holistic score combining all proportion-based metrics — V-taper, waist-to-hip ratio, shoulder-to-waist ratio, limb proportions, and symmetry — into a single number. It reflects how closely your overall body proportions align with classical aesthetic ideals (the "golden ratio" physique). This is purely about shape and proportion, independent of how much muscle you carry.

Measures how clearly the three heads of the deltoid muscle (front, side, and rear) are visually distinct from one another and from the surrounding muscles. High separation indicates low body fat in the shoulder region and well-developed deltoids. This is often the first place visible muscle definition appears as someone leans down.

Each posture metric measures alignment of a specific body region using the photo as a guide. Good posture not only looks better — it directly impacts muscle development, injury risk, and athletic performance. The AI checks for forward head posture, uneven shoulder height, spinal curvature, and hip tilt from visible landmarks in the image.

An estimate of how far along you are toward your maximum natural lean physique potential, based on your current estimated body fat, lean mass, age, gender, and fitness level. It's not a comparison to others — it reflects your individual progress arc. A score of 100% would mean you've reached peak natural conditioning. Most advanced athletes sit in the 60–80% range.
