One hour, Just for you!
For parents at local schools in Barnet & Finchley
Who we are:
We are a North Finchley based private fitness studio, not a big commercial gym where you walk in and figure it out alone. Every session is led by an expert coach, in a small group, with a structured programme designed to get you real results. Think of it as personal training in a community setting without the personal training price tag.
A schedule that works around you
Built around the school run, our daytime classes start from 9:15am so you can train and be home before the day begins. With over 40 coached sessions every week across mornings, evenings and weekends, there's always a slot that works, whatever your week looks like.
Ready to give it a try?
You can try 2 fully coached sessions for just £10 saving over £40. No joining fee, no contract, no commitment.
Small group coaching. All levels. Every week.
Every session at Onyx is coach-led in a small group so you get the structure and attention of personal training, in a community setting, at a fraction of the price. We also offer 1-2-1 personal training and have an on-site osteopath for individual support.
A progressive strength programme for any level. Structured around an 8 week rotation with a coached full body split so you get stronger, build confidence and protect yourself from injury, without having to figure out the programming yourself.
Push yourself in a structured, pre programmed conditioning session. Testing endurance, speed and teamwork using strength, bodyweight and aerobic movements. Energetic, fun and rewarding every single time.
Footwork, pad work and bag drills from the ground up. Beginner or experienced, you will leave feeling energised and with a real sense of achievement. No experience needed. Just energy and willingness to work.
Improve range of motion, strengthen joints and muscles, and get your body moving as it was designed to. FLEX improves daily movement and boosts performance across every other session. Often underrated and always essential.
Fully bespoke 1-2-1 coaching built entirely around you. Your goals, your schedule, your starting point. Work one on one with an expert coach on a programme tailored to nothing but you.
An on site osteopath works directly from the gym. Carrying an injury, managing chronic pain, or just want to move better? Expert help is right here. No GP referral needed. Just book and come in.
Hundreds of five star reviews from local members in Finchley, Barnet and Whetstone.
Onyx is the best gym I have been to by far. It feels like a group PT session, which is the opposite to most gym classes out there. The coaches are brilliant and really take the time to help you.
The classes are fun, inclusive and cater to all levels whether you are a beginner or advanced. The team have created something really special with a great atmosphere that makes it a great place to train.
I was living in a new area and took a chance. A few days later I was at my first Build class at 7am and have not looked back since. Training is excellent in small groups and the coaches are attentive, correcting form, giving advice and always motivating.
For anyone intimidated or nervous about walking into a gym environment, with Onyx you do not need to be. Small classes led by excellent coaches and friendly members. You will have fun and get a great workout at the same time.
Best gym I have been to. Love everything about it.
Excellent gym. Great coaches, good training programs, always clean and well equipped.
