Meet the 29-year-old London banker who runs a £1.2 million fitness company

But for Tom Exton, the end of his day at the office only marks the beginning of his main pursuit - LDN Muscle, the fitness company with a turnover of £1.2 million ($1.5 million) he co-founded with twin brother, James, and two friends, Max and Lloyd Bridger, in 2013.

What started as a blog is now a series of downloadable training guides and nutrition plans. The brand has grown in reputation on social media, with LDN Muscle transformation photos contributing to its following. The company currently has 165,000 followers on Instagram and 138,000 on Twitter, while Exton himself has an Instagram following approaching 100,000.

With a clothing brand, a personal training academy, an app, a supplements range, and a "Lean in 15" style new book launching this week with fitness moves and recipes, Exton appears to only just be getting started. And all of this while balancing full-time job spotting potential money-launderers for Barclays, according to the Evening Standard. Scroll on to see a day in the life of Tom Exton.
