About UNDRGRND TRaining



Imagine the best possible nightclub; tunes spun by an incredible DJ who just seems to “get” the room, it’s dark so you can lose yourself in the lights, and you’re surrounded by the best humans who are bringing high-energy vibes and pumping up the room. 

Now take that nightclub and pop a weight in your hand – that’s UNDRGRND Training. 


Every class is a party where you can immerse yourself in the moment, forget the outside world and let the music drown out all distracting and intrusive thoughts

Jack Gates

After more than seven years in the fitness industry I was keen to work somewhere that valued members. So I built that space with Tim, a mate from footy. 

My vision has always been to create a space where the member and their experience is at the centre of everything. For me, UNDRGRND Training should always be the space you can’t wait to visit, and where you always leave with a smile on your (sweaty) face. 

Come closer, I’ve got a secret…I feel I could have been the secret sixth member of the Backstreet Boys. For real. 
If you happen to know the boys, could you slip in a good word about my skills 😜


Tim Peterson

In my more than seven years in the fitness industry I’ve always wanted to evolve and change the way people approach and view exercise. Just like my business partner and good mate jack, I’ve never felt comfortable focusing only on how people look and perform. I wanted to focus on how people feel, and what’s going on inside rather than outside.  

And we’ve done exactly that with UNDRGRND Training. But even better than that, we bought together a community of excellent humans who connect have heaps of fun, feel comfortable in their skin, and also happen to feel strong, not just look strong.

Did I mention that I am the proud holder of a local Pizza Hut record? When I was a bit younger I ate 21 pieces of pizza. Oh, and I have a bit of an obsession with scented candles, but we’ll keep that just between us 🤐
