Hey there, Elliot here. I’m the owner and head trainer here at C3 Marrickville. I’ve been in the industry for over 11 years, having previously run my own boot camps as well as managed multiple F45s across Marrickville, Petersham, and Neutral Bay.


You’ll generally find me at the gym with my dog Toast (golden retriever). Most importantly, I joined the fitness industry to celebrate what our bodies can do, and not what they can’t. My team and I are here to help allow each person to discover their own unique strengths.
