Cannot recommend enough!
I’ve very new to the CrossFit/functional fitness space but was recommended Sleven and it has been incredible. The team are friendly, welcoming and knowledgeable, you’re given the guidance and help to really push yourself no matter your previous experience and skillset. The classes and workouts are challenging but super enjoyable and you can tell that thought and purpose have gone into designing them! Honestly just give it a go and you won’t regret it!

Sleven Fitness is hands down one of the best CrossFit gyms I’ve ever trained at. The coaching quality is exceptional – every coach is incredibly skilled, attentive, and genuinely invested in helping you improve, whether you’re a complete beginner or more experienced. I feel always supported, corrected, and encouraged in a way that pushes me forward safely and confidently.
The management team is also outstanding – super approachable, helpful, and always willing to go the extra mile to make sure members feel looked after and part of the community. Class times are well structured and accessible, the facilities are excellent with plenty of well-maintained kit, and the overall atmosphere is welcoming, motivating, and inclusive.
On top of that, the community vibe is brilliant – friendly, inspiring people, great energy in every session, and plenty of opportunities to connect through events and training. I genuinely couldn’t recommend Sleven Fitness more. 💪🔥

I absolutely love training at this gym! The coaching quality is outstanding — the coaches are knowledgeable, supportive, and always make sure you’re improving while staying safe. The class variety keeps things exciting, and the atmosphere is super friendly and motivating, no matter your level.

It’s such a welcoming, beginner-friendly place, but also full of inspiring people who push you to do better. I genuinely enjoy it so much that I’m always trying to bring friends with me to try it out — I can’t recommend it enough!

Genuinely the best gym I’ve been to in London 🥹 I’ve only been training here for a short time but in that time every coach has remembered my name, given me some really helpful tips and I’ve thoroughly enjoyed every workout! You can tell the community are genuinely happy to be training there and the gym has a number of events organised throughout the year to strengthen this. So happy to have found Sleven, I only wish I had joined sooner!
