Personal Training & Nutrition

header graphic 1 Shelves

I launched my business as a Personal Trainer in January 2009 and have been lucky enough to work with some amazing people during this time. Every client I have worked with is special and unique to me, and I pride myself on offering a level of service that is personalised, facilitating life change that stretches beyond that hour or two a week.  

I don’t believe in being cooped up indoors all day – training should be an escape from the four walls of the office, and not a slightly smellier version of it (e.g. underground gym dungeons!) This is why I have chosen to train my clients in the great outdoor spaces of London. I am obsessed with running, but I won’t force you to run the next marathon with me, although I wholeheartedly believe you can, it just takes some people longer than others.

The success of any fitness programme is inextricably linked to correctly balancing exercise with nutrition – whatever your goals are you won’t get there by putting the wrong fuel in the tank. In 2011 I graduated as a Nutritionist with First Class Honours and so my offering is unique in providing best practice training and nutrition that is based on Scientific rigour and not the latest fad.

I have got people in shape for weddings and holidays, shaved times off PBs, helped people with injury rehabilitation and back care, trained people before and after births and a whole lot more. I am also a freelance health journalist, writing regularly for titles such as Triathlete’s World, Runner’s World, Professional Photographer (regular columnist) as well as BodyFit and the Sunday Telegraph.

What I've been up to....

September '10 - 11


Resident Personal Trainer on SKY 1's 'A League of their Own' Sports quiz, with team captains Jamie Redknapp and Freddie Flintoff, hosted by James Corden. The role included demonstrating some of the fitness challenges onscreen for the 'reveal' and coaching the celebrities on how to safely perform the exercises. Running on the same treadmill as Mo Farah for series 3 was a definite highlight!

January - December 2012


Founder and team leader of the '12in12' (, a yearlong fundraiser for charity HOPEHIV, whereby a team of 27 spent 2012 raising funds for children orphaned or affected by HIV/AIDS in sub-Saharan Africa. My challenges included Disney World, London and Edinburgh marathons, my first ultra (35M), my first Olympic triathlon, bog snorkelling triathlon, cycling London to Paris and Bruge to Amsterdam, the 3 Peaks Challenge, trail running and Scotland Coast to Coast. I finished the year running 12 marathons in 12 days from North Yorkshire to London, with a team of three other runners. I also organised various fundraisers throughout the year such as spinathons, yoga challenges, swimathons and sports day races. As a team we raised over £160,000 for HOPEHIV, which I am delighted about, and I have now committed to working one day a week within HOPEHIV organising further sporting this space!


May 2013 onwards....


Pulling together my love of both FOOD and RUNNING, I write a monthly Nutrition blog for Runner's World. My column is devoted to picking out top ingredients, explaining their benefits for runners and then wrapping them up into great, inspiring recipe ideas that will tantalise the tastebuds without packing on unwanted pounds.

Bridal training is a speciality of mine, and I love nothing more than seeing gorgeous girls rocking their wedding dresses! I recently filmed a series 'Bridal Bootcamp' on My Wedding Scrapbook: instructional videos for brides, including some of my favourite conditioning moves to do at home, and videos from the kitchen on how to eat clean in the run-up to the big day.
