Track physique progress.

Training levels measure what you lift. Physique measures how you look. The two never mix.

A physique scan is a photo-derived view of your appearance at a particular moment. It gives you another way to review progress alongside the weights and repetitions in your training log. The result is not a direct measurement of how much you can lift, how much muscle tissue you have, or how healthy you are. SET keeps this track separate because those are different questions.

The scan can describe visible proportions and estimate appearance-related scores. Treat the numbers as model outputs, not lab measurements. A camera records a two-dimensional image under specific lighting. It does not directly measure body composition, and a precise-looking number does not remove that limitation. If you need a clinical assessment, this feature does not provide one.

Use the result to organize a visual history, then interpret it with context. A training log may show stronger lifts while a photo looks similar. Photos may look different when your performance is stable. Neither observation requires the other to be wrong: performance, appearance, pose, clothing, and capture conditions are different inputs.

Choose a repeatable place for your photos. Keep the camera at a similar height and distance, use the same orientation, and avoid switching between a wide-angle close-up and a distant shot. Include the same body regions in each frame. A comparison becomes less useful when one image shows your full body and another cuts off your legs or shoulders.

Use similar lighting from one session to the next. A bright side light and a soft front light reveal different shadows. You do not need a professional setup; a consistent setup is the priority. Avoid filters, dramatic exposure edits, or stretching the image before scanning. Those changes affect the input the model sees.

Keep your pose and clothing comparable. If you choose a relaxed stance, use it again. If the first photo is flexed and the next is relaxed, treat that as a different capture rather than a clean before-and-after comparison. Review several consistent observations over time instead of interpreting every small score movement as a physical change.

A front view only shows the front. A back view adds information that a front photo cannot provide, and side views add another perspective on proportions and posture. The guided capture flows help you collect the selected angles together. Follow the framing prompts so that the comparison includes the regions you want to track.

If you previously used front and back images, repeating that pair gives you a more consistent comparison than changing the angle set at every scan. More views can add context, but they do not turn an image estimate into a validated body-composition test. Clear, repeatable photos are more useful than a large collection with inconsistent framing.

The iOS guided camera provides framing and lighting guidance and a countdown to help you hold a shot. You remain in control of the images you submit. Review the capture before continuing when the app offers a preview, particularly if the frame contains something you did not intend to include.

Images submitted for analysis are sent for inference and are not persisted as server-side photo records. SET stores the resulting scores for your account. This distinction matters: a score history can be available even though the service does not keep an album of the images you submitted.

Optional local copies are different from server storage. A photo retained on your device for the viewer or saved to your photo library is managed on that device. Your photo library may have its own backup or sharing settings. Review those settings if you choose to save images there; the app’s server retention behavior does not control your personal photo library.

Face detection guidance on iOS runs on the device. That does not mean an image you explicitly submit for a physique scan stays entirely on the device: the submitted image is used for remote inference. Read the privacy policy for the data categories and processing details before using a photo feature.

Keep logging the exercises, load, repetitions, and dates that establish your training progress. A physique scan does not add a workout, award training strength, or erase a detraining deficit. Your training levels continue to come from saved lifting data. This makes it possible to inspect both tracks without making one a substitute for the other.

When comparing two scans, first ask whether the capture conditions match. Then look at the interval and the broader history. A single score change without a consistent photo comparison is weak evidence. A repeated visual pattern alongside a well-documented training block is easier to interpret, even though the score itself remains an estimate.

You can also choose not to use physique scanning. Workout tracking does not require photos. If visual scores are not helpful to your goals, use the training log, readiness guide, and strength calculator to focus on performance. The best tracking routine is one whose information you can use without making every day a judgment of your appearance.
