SUCCESS STORIES

Coach Becky makes 1st Place in Malaga 2026
Our coaches don’t just talk the talk, they live it. Taking 1st place in the Málaga Women’s Doubles, and standing proud on the podium with her flag, this is a true reflection of the dedication, discipline, and consistency she brings to every session.
Coaches Jake K, Antonious & Jake F
Jake K, Antonious, and Jake F took it to the podium with a 3rd place finish in the London Olympia relay 🏆 A huge effort from the lads pushing hard, backing each other, and bringing the same energy they bring to the studio every day. The teamwork, grit, and competitiveness on show says everything about who they are as coaches. They don’t just coach it, they compete it, live it, and lead by it!
Member Cherma-Preethi
Cherma-Preethi’s journey is what transformation is all about. Starting from never really working out, she’s completely changed her lifestyle. Dropping body fat, building real strength and muscle, and growing her confidence week after week inside the studio. As she shared: “Thanks to you and all the coaches Sharon, all your energy is contagious and motivation keeps me going. Even start of this year I thought Hyrox even a relay was impossible for me, but now I am happy to reach the point of trying a Hyrox solo… I might not do it great though 😂😂😂 but I have the confidence that I will try and complete it.” And she did exactly that. From the first step to the finish line, this is what consistency, support, and belief can do. 💪

Just starting my gym journey and chose F45 as it’s a group class so everyone gets help and guidance throughout it all which is perfect for a newbie like me. All the coaches I’ve had so far are so amazing, not only do they demonstrate but they watch and guide you to what is best for you. Must be good if I’ve just signed a membership form right.

From the moment you walk through the door, you’re greeted with an infectious energy that makes every workout exhilarating. The trainers are absolutely phenomenal. They are incredibly knowledgeable, motivating, and genuinely invested in your progress. They push you to your limits in the best possible way, always offering modifications to ensure you’re challenged safely and effectively, no matter your fitness level. Their eagle eyes on form mean you get the most out of every movement, and their encouragement keeps you going when you think you can’t. What sets F45 apart is the dynamic and ever-changing workouts. With a huge library of exercises and different daily class structures, you’ll never get bored. Each session is a perfectly curated blend of cardio and resistance, designed to maximise results in a time-efficient way. The screens guiding you through each station make it easy to follow, even for newcomers, and the team environment truly makes you feel like you’re part of something special. Beyond the incredible workouts, the sense of community at F45 Chelmsford is truly remarkable. Members are friendly and supportive, creating an atmosphere where everyone cheers each other on. It’s more than just sweating it out together; it’s building connections and celebrating each other’s victories. Since joining, I’ve seen incredible improvements in my strength, endurance, and overall fitness. But more than that, F45 Chelmsford has boosted my confidence and mental well-being. It’s become an essential part of my routine, and I genuinely look forward to every session.

Overall Amazing! Great classes so much fun. All of the trainers are so friendly it creates a great atmosphere. I went to my first class alone, which can sometimes feel daunting but I felt so encouraged and supported. My partner now comes too it’s a great way to train together! The shower facilities are always clean with lots of useful bits. I feel that compared to other group classes your not always doing the best for your body – with F45 they pay attention to each person and help with movements, corrections which is fab your really getting the most out of your workout. I’m new to the area and so happy I have F45 to train at! 🙂
