You might not know her yet but she reckons she’s pretty famous in and around the gymnasiums of NYC.

'I'm recognized wherever I am,' said Jen. 'I don't really go to public gyms anymore just because it is a whole big scene when I'm there. I don't like being watched.'

Jen realised she was on to a winner after she began hitting the gym and noticing the changes to her derriere.

She joined Instagram back in March 2012 and began to document her progress, with photos of her perfect bum garnering nearly 150,000 likes.
