Hey, so the idea behind the app would be that users would constantly upload photos of themselves, thereby generating a lot of data, that includes their personal information, time of uploads, and hopefully lifestyle information, which would make the images generated by the model more realistic.

For this to work, the generated images would need to be already realistic enough. I think one way to "fake it until you make it" would be to interpolate between someone's picture and a fitness model, in the method introduced by the paper "Generative Visual Manipulation on the Natural Image Manifold"
