Body Scan · Onboarding preview
See what your training hits. Find what it misses.
Body Scan reads your logged workouts across 7, 30, or 90 days. It maps muscle coverage, detects undertrained areas, and turns the clearest gap into your next focused workout.
Read the record
Uses workouts you already logged — no camera body diagnosis.
Map the coverage
Shows which muscle groups were trained and which were missed.
Build the fix
The strongest gap can become a focused Auto Trainer workout.
Start your scanTraining guidance only. Body Scan visualizes workout coverage; it is not a medical or anatomical diagnosis.
