Our Story

The studio the north was missing.

Founded by 2 sisters Paige and Kacey, Onyx Lagree and Co started with a long train to London, a curious mind of what IS Lagree, and a simple frustration. From one class, we had found the workout we loved, and it was nowhere near home.

Pilates wasn't quite enough intensity for us. We didn't like anything HIIT related. But, why was the only thing for the gym? We wanted that community feel. To chat and have a laugh with others. To feel looked after and be able to forget about everything going off outside. BUT we still wanted a workout that challenged our muscles and mindset. 

And that is how ONYX was born - an experience where you get results, but you also have that escapism and you can just feel like the star of the show and be looked after.

How it started

But why lagree?

We already knew about pilates. We already knew about different 'types' of pilates. But, we wanted to find something where the original method and principles were directly aligned with what we wanted.

Discovering the work of Sebastian Lagree and his ever-evolving, patented lagree method, it ticked every single box for us whilst knowing everything we was doing was scientifically backed, and proven to work.

The space

More than 'just a class'

We wanted to create community. We wanted to have a safe space for you to have a laugh, and live your high-life and get the self care you deserve. 

Life can get stressful, busy, lonely - you name it. A class at ONYX we only want you to feel positive. We want to remove ANY stressors you have for that time on the machine.

A friendly face. Instructors that actually remember you. Your complimentary ginger shot pre class. A separate reception area for you to chat. A drink you can order for that post-class reward. 

We want the experience to compliment YOU.


The Refuel Bar

Your post-class ritual.

Every session earns a drink. Our matcha and coffee bar serves nutritionist-approved drinks, so the thing you reach for after class actually works with your training, not against it. No gums or additives - only staple ingredients. And, don't we all love a little pick me up post session?
