"The best gym I’ve come across in Sydney. Such a good atmosphere. The best equipment I’ve seen in an Australian gym. Good classes and friendly staff. Feel like I’ve made a lot of progress already and have only been here a month! 10/10 recommend😋"

“Absolutely love this gym! The vibes are always positive and welcoming, and everything is super clean (bathrooms, equipment and machines). As a beginner at the gym, the classes have been amazing for learning skills, technique, and movements without feeling overwhelmed. I take Zuyi’s strength and glutes class, and it’s honestly one of the best parts of my week. He explains everything, and always pushes us to go a little harder in a way that feels supportive. I’ve already noticed such a difference. Highly recommend!”

I’ve been training at ONYX for about 3 months now, and honestly, I’m loving it. The vibe of the place is great — super clean, plenty of space, and the equipment is really solid. The staff are always friendly and make you feel comfortable as soon as you walk in.
