The 21-year-old model gave fans a glimpse at her workout regime by uploading a video to Instagram on Tuesday (17 December) showing herself hard at work with a personal trainer.
Much like she did in the jungle, Amy looks rather flawless in her lycra gym gear with her long blonde hair pulled back.
She added the caption: "Early morning #gym session with the AMAZING @kpoleonpt - time to get the pack back!!! @kx_life #workout #weights #fitnotthin."
Amy had earlier shared a photograph of herself and her personal trainer. In the pic, she looks fresh-faced and make-up free after a workout.
"Back in my work out haven @Kx_life with my awesome trainer @Ben hearsumpt #doit #boom #train," she wrote.
Amy jetted back to the UK last week after her I'm A Celebrity stint in the Australian jungle, which saw her finishing in fifth place.
Since then, it's rumoured she's hooked up with jungle campmate Joey Essex.
The pair shared chemistry in the jungle and were thought to have gone on their first date to the wrap party before leaving Oz, however Joey later said their first date was yet to happen, although he's looking forward to it.
Amy has already met Joey's close friends and TOWIE co-stars after joining him for his Welcome Back Party in Essex last week.
