Lucy Mecklenburgh works up a sweat and shows off her rock hard abs on sexy fitness shoot

INSTEAD of grabbing cake and candles to mark her fitness brand's third birthday Lucky Mecklenburgh opted for a sweat-soaked celebration in the gym.

The ex Towie beauty and founder of Results With Lucy looked stunning as she worked out in a trendy crop top with a mesh see-through panel and skintight black leggings.

Lucy set up the fitness plans and recipe guides after quitting the ITV show and has since secured legions of loyal fans who follow her every ab-crunching move.

Proving the perfect advert for her own business, Lucy showed off her super-toned tummy in the two-piece get up which flashed her sculpted, muscular abs.

She seemed to have just rounded off one of her signature 45 minute fitness routines which she insists "aren't serious" as she posed for the camera with her soaking wet hair scraped behind her ears.

She then turned to the side and pulled her shoulder forward in a pose where fans could clearly spot her bulging bicep muscles.

In other images she can be seeing getting stuck into tricep dips on a gym bench and lifting dumbbells.

For the weights-based routine the beauty had switched to just a pair of black knickers and a bra which revealed her super-toned thighs while the former reality star seemed eager for her pert bum to get a piece of the camera action as she posed from behind.

The shots to mark the milestone have coincided with the launch of Lucy's new hardcore HIIT regime for advanced gym-bunnies.

The 12-week programme, which adds to Lucy's hundreds of recipes and videos, is said to focus on the "after burn effect" to ensure users burn more calories.

She said: "The new HIIT Harder plan is all about challenging yourself and challenging yourself and adding muscle definition expect it to be hard and seriously sweaty but you will thank yourself with the results!"

Lucy, who used to date Olympian Louis Smith, said the interval form of training helped her get ready for a summer spent in a bikini.

She said: "I do a lot of HIIT training. I swear by it. It keeps burning fat for longer and it’s really fun. That’s what Results With Lucy is all about.
You’re never going to get bored."
