Really enjoyed my trial here, the instructors are great and helpful during the workout, it was a friendly and fun atmosphere. I wanted motivation and something to push me and it’s exactly what I got here. Thanks to Josh and Sharon especially 😄

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.

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.

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! 🙂
