3D optical scans
What is 3D optical scanning?
3D optical scanning captures your body shape and automatically extracts circumference and length measurements (waist, hip, chest, thigh) across the entire body. The result is a detailed full 3D image that lets you visualize body shape and track fitness progress over time.
Shape Up! uses several scanning platforms:
How to prepare
Wear form-fitting clothing — single-layer compression shorts without padding, plus a sports bra (for women) — to achieve an accurate body-shape representation.
What to expect
You stand in the scanning area while cameras capture your body from all angles. Infants who can’t stand are placed in a clear crib. The captured images combine into a 3D avatar that researchers refine and standardize to estimate body circumferences, fat content, and muscle content.
