The TOWIE star has shown off the results of her '6 pack abs' workout in a Twitter selfie, in which the pretty brunette is posing in a revealing gym kit that showcases her impressive abs and the rest of her toned physique, while holding a dumb bell in one hand.
"These are my results after The '6 pack abs' 12 week challenge .. Send me yours! good luck!" she wrote alongside the photograph.
The brunette beauty – who announced she was leaving The Only Way Is Essex during the show's Christmas special – clearly hasn't been taking the time to rest.
Showing that she is relentless when it comes to keeping fit, the 22-year-old took to Twitter the following day to share with fans that she was exercising in the early hours because she couldn't sleep.
"I can't sleep so I am doing planks, press ups & sit-ups in bed!! Wow! Who am I !?" she tweeted early on 7 January.
Since starting her fitness website Results With Lucy, the reality star has repeatedly shared her super toned figure on social media sites, giving fans a glimpse of what her exercise plans can achieve.
Following rumours that she was to appear in Celebrity Big Brother, Lucy confirmed that she will not take part in the show, saying recently: "I've had a few tweets asking me if I'm going on Celebrity Big Brother with Sam Faiers.
"I can confirm that this isn't true. I don't know if Sam is going to be on the show, but I am definitely not."
In testament to her hard work, Lucy was named the celebrity with the best bikini body of 2013, according to a poll.
