How do you time a selfie to make your tummy look good ?

I’m currently in the process of trying to get my sister to like herself more. I’m having a hard time getting her to do her self care routine and I thought that maybe we could take selfies together.<br><br>I’ve seen posts of people over here talking about how difficult it is to take selfies as chubby people and I never really understood until I had to do it. <br><br>I feel like I’m doing something wrong but I’d like a tutorial on how to do it correctly. Please be nice and specific, I’m not that good at this<br><br>Thanks for reading
