About Us

We first opened our doors in August 2012. We have a fantastic location in Milton next to Milton country park so running parts of our workouts are really good.

We believe crossfit is for everybody all you need is patients to learn good form and a willingness to work hard and you will get fantastic results. Here is why it works better than a traditional gym:

  1. High level of coaching means you progress as an athlete.
  2. Diet & support – Means your body shape will be optimised.
  3. Its challenging, fun and different each time you come.

“I enjoy challenging myself as only when I have a real challenge and goal do I train to my best. My Biggest challenge to date was setting a world record for the most consecutive wallballs 452,  I also attempted to swim the English Channel & swam the length of lake Windermere (12.5 miles) in 8 hours and 50 minutes in 2009. Which was a fantastic challenge.“

With a strong background in sport, rowing to Great Britain standard, playing county tennis and rugby to a national standard, exercise is a major part of my life.

Since qualifying, I have coached weight loss classes in the Maldives as well as coaching rowing at Cambridge University.

Outside of competitive sport I am always up for a challenge, having canoed the width of Britain and completed the three peaks challenge. My attempt to cycle from John O’groats to Lands End unfortunately ended early following injury. More recently I have competed in ‘Tough Mudder’ and ‘Spartan race’ events and I’m always looking for new adventures.

Crossfit provides the variety and strength and skills challenges to make it enjoyable every session.

  • Fitness instructor level 2
  • Crossfit instructor Lv 1
  • Bsc hons degree in food and consumer management

Previously employed in the food industry for 5 years as a chef then a product developer , meaning alongside my degree i have a very in depth knowledge about nutrition and diet.

” My passion is fitness and sport of any kind , I’m a true student to the term fitness as an overweight / then underweight teenager, I made all the mistakes and in turn learnt from them and became stronger both mentally and physically to become the person i am today (still learning, but so far from where i was).

I’ve competed in multiple crossfit competitions, run 20 mile obstacle courses and competed against the brownlee twins in a 9 hour charity event … all things i would have considered impossible feats 8- 6 years ago.

My ambition and aim is to impart my years of learning and experience in fitness and weight management, in order to help people avoid the mistakes i made, and in turn set them on a quicker path to be the person they want and deserve to be.”

My motto … “Inspire and be inspired ! ”

I joined the military in 2005 and am still currently serving in the military (10 and a half years to date). I have been a physical training instructor for 7 years.


The main sport in my life is crossfit, which I started practicing 2 years ago, and it has become a great passion of mine. I have always been into running – mainly off road and over hills. As well as this, I have completed various 10km, half marathons and marathons, obstacle races and ultra to double ultra marathons. I have also spent my earlier years doing strongman, powerlifting style competitions as well as hypotrophy and volume training. I have a great passion for hill walking and love the outdoors.

Postural analysis


I have always had a huge passion for Fitness, Nutrition and Sport. Having worked in the Fitness industry now for over 12 years, I’ve gained a vast amount of knowledge & experience. During that time I’ve also seen a lot of ‘gimmicks’ and fads come and go.

My passion for helping others achieve their fitness goals is why I continue in this line of “work”. I genuinely get a kick out of seeing one of my clients do something they thought they initially couldn’t.
Constantly trying to improve myself and learn more is a big focus of mine, I’m always looking for new information and ways to train clients/myself. I’ve found that functional movements performed at high intensity combined with a good diet and 1-2-1 training is the best way to reach your fitness goals. I’ve trained dozens of clients this way with fantastic results.

I firmly believe what you put in, you get out when it comes to training and health. Fitness and Nutrition should be a way of life, and not something that once you reach your goal, you drop.
