What do you show off on Instagram when you're a hot cheating Russian swimmer who doesn't have a gold medal??
Easy ... your ass.
That's the case for Yuliya Efimova's -- the 2-time convicted cheater who just won the silver medal in the 100m breaststroke in Rio.
Yuliya's page is packed with hot bikini shots from over the years -- but thanks to Team USA bad ass Lilly King, it's missing that golden photo.
King famously wagged her finger at Yuliya after beating her down in the 100m semi-final race over the weekend.
Oh, and if you're still looking for that gold medal shot ... that's over on King's page.
