AI Physique Analyzer + 4-Week Program
Free here • Paid in Bodbot, DEXA scans ($50-150), Macrofactor body audits
Upload a front-facing torso photo. Our AI estimates your body-fat range, classifies your somatotype, identifies the muscle groups holding you back, and builds a deterministic 4-week program targeting them. Empowering and analytical. No body shaming, no medical claims.

- Powered by Google Gemini. Free use limited to 10 calls per IP per hour to prevent abuse.
- NSCA hypertrophy guidelines (10-20 sets per muscle per week, 8-12 reps, 60-75% 1RM) drive every set/rep prescription.
- Photo-based body fat accuracy: Borgeson et al. (2022). Smartphone photo body composition validation against DEXA. JISSN.
- Body-fat estimate is ±3-5%. This is not medical advice. Consult a physician before significant body composition changes.

Frequently asked questions
How accurate is the body-fat estimate?+
A single-photo body-fat estimate is typically within ±3 to 5 percentage points of a DEXA scan. Accuracy improves with even lighting, a front-facing torso shot, and athletic wear or shirtless framing. Our model returns a low/mid/high band so you can see the realistic range, not a false-precision single number.
What photo works best?+
Front-facing, full torso visible from shoulders to hips, even lighting, no heavy filters. Shirt off or fitted athletic wear. Stand naturally — flexing inflates muscle separation and biases the estimate downward by 1 to 2 percentage points.
Is my photo stored?+
No. The image is sent to Google Gemini for analysis, the response is returned to you, and the photo is discarded. We do not log image bytes server-side, do not run any third-party trackers on the result, and do not retain the file after the request completes.
How does this compare to DEXA?+
DEXA scans cost $50 to $150 and are the gold standard at ±1.5% body fat. A clinical handheld BIA or 3-DPA scan is ±2 to 3%. Photo-based analysis (this tool) is ±3 to 5%. Use this for a directional read, DEXA for medical-grade precision.
Why does the program target my weak muscles specifically?+
Symmetric development is what makes a physique read as "built" instead of "trained one body part". By prioritising the muscles the AI flagged as lagging, you compress more aesthetic adaptation into the same training volume. NSCA hypertrophy guidelines (10 to 20 sets per muscle per week, 8 to 12 reps, 60 to 75% 1RM) underpin every set and rep prescription.
Can I use this if I am under 18?+
No. The analyzer rejects images that do not clearly show an adult. Body composition guidance for minors should come from a pediatrician or registered dietitian, not an AI tool.
Is this medical advice?+
No. This is a directional read for fitness planning, not a clinical assessment. If you are considering significant body-composition changes, consult a physician and a registered dietitian. The disclaimer on every analysis is there for a reason.
