Fantastic experience: A friendly gym with some of the best coaches I’ve been coached by !!

Sam Roby 6 months ago

Fantastic experience: Joined ATF Fitness thinking I’d “give it a go”…5 months down the line I now own lifters, grips, a weightlifting belt and apparently a new personality. As a knackered mum of 2 I could barely lift the bar off the rack at first. Now it’s a bit easier and I’m throwing weights around my head like I know what I’m doing (I don’t, but all the amazing coaches do, thank God for them). The place calls itself a community but it’s more like a friendly, sweaty, protein shake fuelled gang where everyone wants you to succeed and laughs when you nearly fall over or whip yourself with a skipping rope (lovingly). My husband nagged me for 2 years to try it. He was right. I hate that. But I love this gym and its people. Come for the fitness, stay for the banter. I dare you to find better.

Amazing review Sam thank you! We are so excited that you love it as much as we do!

Fantastic experience: What a community, what a place! Joining ATF is hands down the best fitness decision I’ve ever made. I’ve been coming for over two years now and I’ve learnt so much, but the best part is there’s still so much more to learn and I know I’m in the right place to learn it. The coaching team is genuinely brilliant. Every session is structured, the equipment is great, and most importantly, you can tell that they really care. I stumbled across ATF by chance, but now it’s a core part of my week and I get itchy feet if I can’t make a session. If you’re even remotely thinking about it, just come down. You won’t regret it.

Fantastic experience: I can't recommend CrossFit Against The Fire highly enough. From the moment you walk in, there's an energy and community spirit that sets it apart from other gyms. The Team Kim, Charlie, Daryl, and Gareth are phenomenal. They all bring a unique style, but they all share the same passion for helping members push their limits safely and effectively. Whether you're a beginner or a a Consistent trainer , the programming is challenging, thoughtful and always evolving. The attention to technique and individual progress is unmatched. The workouts are intense but always leave you feeling accomplished. What really sets this gym apart is the culture. It’s not just about fitness it’s about support, progress, and community. If you're looking for a place that will challenge you, support you, and help you grow both physically and mentally, then ATF is The Place to Be

Michael Caton 6 years ago

Fantastic experience: I've been a member for a few months now. I had never worked out before, let alone been to a crossfit box. I arrived with a mixture of excitement and trepidation. At first it was hard to get through the warm ups let alone the work outs. The coaches there have been great, directing me around the various exercises that all seem so strange at first. They are exceptionally knowledgeable and encouraging. Now I struggle if I have to miss a session. I imagine this to be more about the friendly atmosphere and encouragement of this particular crossfit club. Thank you Kim, charlie ad the others and keep it up.

CrossFit Against The Fire (ATF Fitness)

Thank you very much Michael and always great to have you in the session.

Fantastic experience: I visited this box for a few weeks whilst I was over from Australia visiting family - everyone was very friendly and welcoming and Kim made it so easy for me to sign up for a membership that suited my needs. The programming is excellent - you get so much from the hour, and the classes are run very well. Everything is explained clearly and scaling options given where needed. There are so many class options, that whatever your schedule you'll be able to attend. Will definitely be back next time I am in England and would definitely recommend! Michelle B x

Fantastic experience: Fantastic box. The trainers give the most helpful advice: specific, tailored and doable. They're also incredibly motivating and want you to feel supported and encouraged, regardless of your ability. The whole community at this box is the best I've experienced within UK and overseas. Never a dull moment and on the days you feel like you can't do it, there's a member telling you you can. Will wear my Crossfit Crayford t-shirt with pride!
