J21 Tube's video: Fitness first Lucy Mecklenburgh in a white bralet gears up for workout session in Marbella sunshine

Fitness first: Lucy Mecklenburgh displays her incredibly taut abs in a white bralet as she gears up for workout session in Marbella sunshine Over the years, she's turned her devotion to fitness into a burgeoning business empire. And Lucy Mecklenburgh showed that her commitment shows no sign of waning, as she was spotted getting into the zone for another workout during her trip to Marbella on Thursday. The 26-year-old former TOWIE star displayed her enviably taut abs and toned physique as she walked along the promenade in a white bralet and black leggings - from her line with sports giant Ellesse. With black Nike trainers rounding out her sporty ensemble, the brunette beauty chatted with a male pal as she soaked up the balmy Spanish sunshine. She let her natural beauty shine through as she went makeup-free for her day out, while her wavy chestnut tresses were set in a relaxed ponytail. Later in the day, she slipped into different workout gear, stepping out in a floral tank top with black leggings. Lucy soared to fame on the ITVBe show in 2010 as one of the original stars in its inaugural series, in which she became the centre of many messy love stories surrounding relationships with Mark Wright and Mario Falcone. Having departed the show in 2013 before forging her own fitness website, Results With Lucy, which sees the star run a subscription service with exercise and dieting videos for her legion of loyal followers. Always one to remain devoted to her brand, the Essex native used her trip to Marbella as a window for research as she headed on a week-long boot camp. The outing comes after Lucy has been stepping out with a new tattooed beau. Lucy reportedly met her handyman boyfriend Nathan Sharp after he did some tiling work on her bathroom at her home in Essex. She is said to have hit it off straight away with the 37-year-old father-of-two. One of Nathan's friends recently told the Sunday People : 'Nathan went to tile a bathroom and came away with a stunning celebrity ­girlfriend – it’s the stuff of dreams.' Lucy is said to be enjoying dating a non-celebrity, particularly as her previous relationships played out in public haven't worked out. She has previously dated gymnast Louis Smith. The reality star turned fitness guru was first seen out with Nathan, who split up with his wife Rachel last year, in September as the pair enjoyed a dinner date at Alex's bar and grill in Brentwood. She unwittingly found herself at the same restaurant as ex-fiancé Mario and his new girlfriend Becky Miesner.
