Onyx Fitness
every session has a purpose
every member has a plan
nobody trains alone
Onyx is a private coaching gym in North Finchley, London. We offer coach-led classes, personal training and a community built around actually showing up and actually getting results.
Most gyms just give you access. We give you a programme, a coach and a community.
At Onyx, every session is coach-led and every programme is designed with purpose. There's no wandering the floor wondering what to do, no training in isolation and no wasted effort. You get expert coaching, a structured plan and a group of people around you who show up consistently because that's what actually drives results.
This isn't just about the hour you spend with us. Onyx is built to support every part of your training life from coached sessions and 1-2-1 training to programming you can follow anywhere and in-house support when your body needs it. This is what training properly actually feels like.
