Onyx Fitness Ltd

Onyx is the best gym I've been to by far. I used to always avoid classes in gyms, but Onyx classes are fun, personal and progressive. It feels like a group PT session, which is the opposite to most gym classes out there. I love going here as the coaches are all really nice people and really experienced trainers.

AMAZING GYM!!! Onyx has great facilities and high quality equipment. Classes are always challenging in a good way which keeps you motivated! They focus on ALL the different muscle groups, movement and mobility; always ensuring that we are all using the right technique. All the trainers are very supportive, encouraging and knowledgeable. The aftercare from all the team is amazing. Atmosphere is comfortable for people of any age, shape, and fitness level. It makes me WANT to go to the gym. The best private gym I have ever trained in. I definitely recommend this gym.

My second year with Christian and though I’ve moved out of the area, I have kept my training sessions with him. Highly professional, he’s meticulous, has great people skills (puts one at ease), and monitors the progress. Training is never boring and I’m very happy with the results,

I absolutely love this gym! The sessions are a perfect blend of challenge and accomplishment. The trainers are phenomenal, providing excellent guidance, and the programs are both diverse and effective.Living nearby is a huge plus, allowing me to regularly enjoy the positive atmosphere and supportive community. Every workout feels like an investment in both my physical well-being and overall happiness. Good job guys!!

Been to a few sessions and can already tell you won't find a gym like this anywhere else in London, let alone North London... Definitely worth checking out if you're tired of the standard, stale, soulless gym atmosphere currently plaguing the city.If you're looking for a gym, or enjoyable/unique classes that will help you get fit & strong - whilst keeping you motivated, definitely hit up Onyx London.

Been a member for a few years now.The team are brilliant and make sessions feel very personal.Simply The Best .

Got recommended by a friend and she did not exaggerate how good this gym is. Solid group PT sessions, I go two times per week and getting so much stronger with good weight training programs, which help a lot with other sports I enjoy. On top of everything, I can feel that the tendon pain on my back left thigh, which bothered me for almost three years, are just getting very much in control now since the weight training started. Magic!Muay Thai sessions on Wednesday night is very stimulating! There are two experienced coaches who really demonstrate the technique, go into details with the sequences and very observant when giving corrections. There are people who are more advance but the vibe of the class is definitely supportive and beginner friendly(meʅ（◞‿◟）ʃ).

Christian, Jack, Clark & Ellie, Ibi & Natasha & Thierry have been absolutely amazing! I was searching for gyms in the area Whetstone for 6.30 am morning classes as I have to work. There were hardly any, but I found this little gem! Ellie was so understanding about my asthma unlike another chain gym down the road! Also they show you the technique if you get it wrong (again other gyms don't focus on this) and I have burnt lots of calories during these sessions as you work hard! Love it and will continue coming. Thank you!!

Onyx is an absolute gem. Fantastic (and brand new!) equipment with highly professional trainers who really challenge you to push yourself physically and mentally. What I like most about is that the trainers make rigorous exercise fun, I made friends with fellow members and trainers instantly. Great community feel and fantastic range of classes. Can't recommend it enough.
