The 24-year-old former TOWIE star flaunted her incredible toned six-pack in a skimpy crop top and skin-tight leggings as she posed in the confines of the gym.
Lucy, who recently split from her gymnast beau Louis Smith, looked magnificent in the self-snapped shot which flaunted her long legs and taut abs.
The Essex native looked extremely pleased with herself in the shot - with great reason given her ripped body.
She added the caption: 'Sooo sore after working out today... it’s all worth it though' and despite the gruelling nature of her work-out, Lucy still managed to look picture perfect, Beauty.
Atop her work-out snap, Lucy, who is the founder of Results With Lucy fitness scheme, also shared a video documenting her gruelling exercise which showed off her expert moves. www.tblook.com
