"Best Gym in North London"

Great environment for classes and PT 1-2-1s, the PTs at Onyx are knowledgeable and really help in all aspects of training, pushing your limits, testing your strength, helping with any issues. Friendly atmosphere and excellent set up.

"A boutique gym with top coaches"

I joined Onyx from a mainstream gym as I was tired of doing my own thing and as a result suffering repeated injuries. Onyx has been a breath of fresh air, I now enjoy going to the gym and each class is like a personal training session.

The expertise of the coaches is second to none, they really going the extra mile when planning classes and ensuring you adopt the right technique. Having been a member at Onyx for the last two years, I can’t see myself moving anywhere else and if you want to get fit, join Onyx.

"The best gym"

The best gym, trainers, environment and atmosphere. Couldn’t recommend it enough.
