Just a guess, but A. She's clearly retired, B. I don't think she's in the same shape she used to be in, and is maybe embarrassed to be on camera on her old accounts. Her physique was a full-time job. Nobody looks like that naturally, and if she isn't making money off fitness content anymore, there's no way she still looks like that. Of course she's probably still a 10, but she's probably feeling self-conscious.
