What we do

THREE WAYS TO TRAIN.

Every path is properly coached, with no guessing and no wandering the floor on your own. Not sure which is you? The 60-second finder sorts it.

ONYXRBT

Results Based Training

Low in energy and confidence? Want to lose 8–12kg in the next 3 months and actually keep it off? This is exactly what Results Based Training is built for.

For weight loss & transformation
ONYXCLASSES

Classes & Conditioning

Coached group classes built on strength and conditioning, with the energy of training beside other people. Turn up, get told exactly what to do, and work harder than you would on your own. Hyrox prep available on request.

For fitness, energy & consistency
ONYXPT

Personal Training

Tried it alone and drifted? Want a coach on you one to one, with every session built around your body, your goal and your schedule? This is the fastest route there is.

For individual, focused goals

The gym

NOT JUST A GYM.
A STANDARD.

Onyx is more than a gym. It's something we've spent over a decade crafting. Coaches here don't just bring experience; they bring the want and the determination to help you actually achieve your goals.

That's backed by a state-of-the-art facility, and a promise to every member who signs up: a clear roadmap from day one, so you always know exactly what you're working towards and what you'll walk away with.

The Onyx app

YOUR NUTRITION,
TRACKED PROPERLY.

Most gyms focus on your training and stop there. We don't. RBT and PT members get the Onyx app from day one: nutrition logged, macros dialed in, and a coach holding you accountable every step to your goal.

"Since working with Declan over the last year or so, I have managed to drop from 96kg to 82kg and have been able to maintain my results while increasing my strength and fitness to a new level. Without his support and guidance, I don't believe I could've achieved these results on my own. 100% recommend!"

"I had struggled getting back to training and being consistent with my diet post-COVID. It was the best decision I made reaching out to Declan and starting training. I have gained so much knowledge around training and nutrition that would never have been possible. My results so far have been losing 7kg of body fat, gaining muscle, lifting heavier than ever before, being fitter than I've ever been, and in general, much happier."

Before you ask

QUESTIONS,
ANSWERED.

No. Most people who join are starting from scratch or coming back after a break. Every plan is built around where you're at, not where you should be.

Depends on the path. Classes are pay-as-you-go, so you bulk-buy your sessions with no contract and no minimum. Results Based Training runs on a minimum 3-month commitment. Any shorter and there simply isn't enough time for us to put a real plan in place and get you actual results.

Yes, built in from day one through our app. You'll log your workouts and nutrition, get set calorie and macro targets, and a meal plan designed around them, plus recipe books, with more added all the time. Whatever your schedule or experience with nutrition, the goal is to make hitting your targets as easy as possible.

Tell your coach on day one. Programming gets adjusted around it. The goal is progress without aggravating it.

Pricing for every path is listed in our booking app. Got a question before you sign up? Just send us a message and we'll talk you through what fits your goal.
