CrossFit Uckfield is one of the largest ‘boxes’ in the UK. We train competitive athletes, ex-gymnasts, golf pros, new parents, grandparents, 5 year-olds and teens.  We have adaptive athletes and those with special educational needs, the overweight, the underweight, the scared and the bold.  We have three CrossFit coaches who take sessions on every day throughout the week. CrossFit Uckfield is a community first and foremost of amazing people who train hard together each week; we work hard to cultivate a positive and encouraging atmosphere so that any newcomer feels welcome instantly.



We provide top-quality strength and conditioning coaching, health education and nutrition support for our members.  We work hard to cultivate a safe, non-judgmental, effective and competitive environment for anyone to train in.   



Paleolithic living as a dietary concept was first promoted by gastroenterologist, Dr Walter L Voegtlin. His book, The Stone Age diet, was published in 1975 and paved the way for a plethora of different Paleolithic approaches, all similar in their core principles but with varying rules and restrictions. Common terms for these types of diet include the caveman diet, the hunter-gatherer diet and of course, the Paleo diet. We promote the fundamental principles of paleo while encouraging people to tailor it to their individual lives.



We are all heros. At our gym you’ll learn how to empower yourself to believe you truly are one too.

Whether you’re a former athlete, are completely new to fitness, or are somewhere in between those two extremes- you’ll find a home within CrossFit Uckfield. We are a diverse community built on the common belief that there’s something more to accomplish, and we will work together to get there. We enjoy our quality time in the gym but also enjoy social outings and various adventures outside of the gym.

CrossFit Uckfield is a place where you can challenge yourself physically and mentally, but find that you are supported by our coaching staff and by the members and athletes around you.
