Trainer Connect is the first personal trainer app in the world with AI-powered body composition analysis from a photo. Take the body assessment photos and the AI estimates body fat percentage, somatotype, posture, and muscle asymmetries in seconds — no bioimpedance, no skinfold caliper, with the accuracy of the world's most advanced multimodal models.
In 4 simple steps, right inside the app, you turn a traditional body assessment into a complete visual analysis powered by artificial intelligence.
The student records consent in the app (once), as required by LGPD. They can revoke it at any time under "Profile → AI Analysis."
During the assessment, take front, back, and side photos. Workout clothes, neutral background, even lighting — the better the photo, the more accurate the analysis.
The Claude Sonnet model (by Anthropic) processes the images and generates estimates for body fat %, lean mass %, somatotype, posture, and asymmetries.
Values appear editable so the personal trainer can review them. Clinical interpretation is always up to the professional. Everything is logged in the student's assessment.
A complete visual analysis that goes far beyond a number on the scale. Everything a personal trainer needs to prescribe evidence-based training.
Visual estimate based on body fat distribution, muscle definition, and body proportions. Useful for ongoing tracking between clinical assessments.
Estimate of visible muscle mass, calibrated by gender, age, and skin tone. Detects lean gain/loss between assessments.
Ectomorph / mesomorph / endomorph classification (or mixed type), based on bone width, muscle mass, and fat distribution. Essential for personalizing diet and training.
Identify hyperlordosis, kyphosis, anterior pelvic tilt, rounded shoulders, and other postural issues visible in the side-view photo.
Detection of imbalances between sides of the body (right vs. left arm, right vs. left leg) and disproportions between muscle groups (torso vs. lower body).
The AI generates qualitative observations that help trainers plan corrective workouts: prioritize back work if there's kyphosis, prioritize core if there's lordosis, and so on.
Traditional body assessments depend on expensive equipment (segmental bioimpedance, DEXA, skinfold calipers) or manual measurements that vary widely between examiners. For trainers working online, in gyms without the right equipment, or offering remote coaching, equipment barriers have always limited continuous tracking of a student's body composition.
AI-powered visual analysis changed that game. Multimodal models like Claude Sonnet, by Anthropic, were trained on millions of images and can identify subtle anatomical markers: fat tissue distribution, muscle definition, body segment proportions, and postural patterns. This enables them to generate useful body composition estimates from standard physical assessment photos.
It's not a substitute for high-precision DEXA or bioimpedance scans — it's a practical, accessible complement. Trainers can run multiple analyses throughout the month to track a client's progress between formal clinical assessments, spot trends (losing lean mass? gaining belly fat?), and adjust training more quickly.
Body analysis requires photos. Photos require responsibility. Trainer Connect was built with privacy by design.
AI analysis only runs after the student explicitly authorizes it, logged in the app with date, time, and consent version. The trainer can also record consent on the student's behalf (with their agreement, in person). The student can revoke consent at any time under "Profile → AI Analysis."
Photos aren't sent to the AI in bulk. Each analysis generates signed URLs with a short expiration, used exclusively for the Anthropic request. Once processing is done, the links expire automatically.
Anthropic maintains a zero retention (zero data retention) for enterprise clients via API: images are neither stored nor used to train models. All processing is ephemeral.
The values generated by AI are editable suggestions. The trainer reviews each field before saving it to the assessment. Clinical interpretation and the final prescription are always the responsibility of the professional with proper professional registration.
