Can someone Id this girl?

Probably not. There are so many Chinese fitness enthusiasts now and to a random Westerner they look almost the same. One exception are the few famous or better known ones. Another exception is if someone happens to be a fan of this particular one.

Where is this from? It would help if you could copy and paste here any of that text.

I OCR'd the account name (半杯风情) and Google gave me this (hsiwang168), but I can not access it now to verify.
