Onyx's Vision

Onyx is the collaborative vision of 5 coaches and friends.

    • Functional Strength – structured strength training using a variety of free weights and bodyweight techniques

    • Onyx Flow – a class designed to reconnect you with your body and have you moving well

What People Have To Say About Onyx London

My training has improved significantly since onyx. Its challenging, fun, intense, and safe given Im someone who has had extensive injuries in the past. Would say Its a good place both for beginners and people who like to be challenged. Trainers are experienced, professional, and all round lovely humans.

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.

Amazing gym, I trained with Ibi and I have noticed a huge difference not only the way I look but my overall health. He is extremely detailed and patient. If you are looking for a PT, I highly recommend Ibi.
