Venezuelan fitness model Michelle Lewin took in some rays at the beach in Miami this week, wearing a skimpy thong bikini to show off her voluptuous curves.

Lewin, who has not one, but TWO Instagram pages, often shares selfies and modeling shots on one page, while sharing photos and videos from her bodybuilding sessions on the other.

If that wasn't enough, the 28-year-old beauty currently has 683 photos and videos on her Twitter page -- talk about self-promotion!
