The Hot Right Now, 32, songstress gave her Instagram followers a glimpse into her fitness routine with a series of snaps taken in Sydney.
They captured Rita in a Pilates equipment studio, wearing grey leggings and a black cropped hoodie.
Her amazing figure was on full show as she completed a series of plie squats with weights, before stretching out over the barrel.
After some push-ups she switched to some side body work before heading to a reformer machine with a Swiss ball.
The Shine Ya Light hitmaker then laid back on the cadillac machine with the ball to finish off with some glute bridges.
Rita tagged her Pilates trainer and the studio in Australia before gushing about her sweat session in her caption.
She wrote: “I decided to use what I love with other things I love – hence why the sound is off I was playing my new album while working out!
“Hmmm should I set up a competition to do a one on one class with me and my trainer (don’t worry it won’t be to hard) with a lucky fan who wins the competition (whatever it is I don’t know yet) and potentially play new songs off the album and show them some secrets of who the features are?!!”
Rita recently kept up her Pilates routine while taking a trip to New York.
Last month, the chart star looked incredible as she showed off her gym-honed body in workout gear.
She also previously stripped to her underwear for a selfie after hitting the gym.
The Sun recently revealed Rita has named her third album after her husband Taika Waititi.
The record titled You & I is all about finally finding The One with the New Zealand director, 47.
You & I is Rita’s first album in five years and her first since signing a bumper deal with BMG.
Talking about the album, Rita said: “This album really means a lot to me.
“It’s like my diary of the last few years, it’s my sound and it just feels so true to me and who I am today.”
