'Life is better after 300 sit-ups': Ruby Rose shows off her washboard abs in sports bra and baggie trousers after gruelling workout

She's been working hard to build up strength after landing roles in two action films.

And Ruby Rose appears to be keeping up her fitness regime, showing off her rock hard abs after an intense sit-up session.

Showing off her ripped physique in a post to Instagram on Friday, the 30-year-old model turned actress posed in a white crop top teamed with baggie black trousers which were cropped at the ankles.

She completed her fitness chic look with tie-up black boots, while styling her raven tresses in a messy but stylish do.

'Life is better after 300 sit-ups,' a make-up free Ruby wrote alongside the snap of herself posing in front of the mirror and showing off her colourful body art and the outline of a six pack.

The post comes days after the former MTV VJ's skills were called into question by California DJ Josh Billings in a Facebook video posted on Wednesday which suggests part of her set is pre-recorded or pre-mixed.

Josh shared a clip of Ruby performing at a Tryst Nightclub in Las Vegas over Labor Day weekend last year and wrote:  'Unless she's dropping The Weeknd a capella separately from this beat, she's not mixing anything right now. So I'm not even really why she threw that fader up.

'If you see like in a few seconds here I think she just turns the fader up for no reason. It's very weird.'

He added: 'Anyway she's fantastic at lip syncing, dance moves are top notch. Super impressed by all those. But as far as DJing, not very impressed.'

Later in the video, Josh observes: 'You can see her looking at CDJ right now to try and find the next track to play and everything.'

Meanwhile, Ruby responded civilly to Josh's criticism on Twitter, saying: 'I play a lot of bootlegs and a lot of mashups. Come next time and I'll show you.' 

She also explained there were some technical difficulties during the 2015 performance. 

Criticism: The basis of Josh's claims are the on-air red lights visible on Ruby's CDJ, a specialized digital music player used for DJing, which show when the faders are up
