Fit3D is a web platform that leverages 3D imaging to track health metrics over time. Users get weekly body scans at Key Fit Club and can track their 3D avatar, extracted body measurements, and health metrics over time at fit3d.com. Fit3D provides users with an objective way to track changes in their body as they put in the effort to eat healthy and workout.
This really depends on the fitness plan in which you are taking part. Please work with your trainer to come up with the best scanning schedule for you.
