Come home to the fittest version of yourself.
We’re all about functional fitness and high quality movement education and coaching, in other words, we teach you to move bigger loads better.
Whether you're focusing on weightlifting or building strength, we’ve designed a training system that lets you choose your track—think CrossFit, but without the higher skilled gymnastics and more focus on strict movement. Our programs also prioritize cardio development, helping you boost endurance and overall health.
But what truly sets Siege apart is our community. You'll experience the most supportive team environment, where everyone is invested in your success. Here, you’ll feel right at home, building healthy habits and smashing your training goals.
Coaching Thornton and Maitland for over a decade
Siege has been training the Thornton and Maitland community for more than ten years. Same idea the whole way through: small classes, proper coaching and a room full of people who back each other.
We sit somewhere between CrossFit and functional fitness. You'll lift, carry, push and pull, and build a real engine, without the high-skill gymnastics. Strict movement and good technique come first.
Our members aren't chasing a six-pack for summer. They're parents, shift workers, tradies and people who are the one others rely on. They train so they can keep up, lift what life throws at them and never be the one someone has to look after.
You train because you're responsible for more than just yourself.
The reason most of our members walk through the door.Why people stay
Coached, not supervised
Classes are small so your coach can actually watch your lifts. Every session is adapted to where you're starting.
Programming that works
Our PERFORM program blends strength and conditioning, planned week to week so you keep progressing.
Built for real life
Getting off the floor, carrying the shopping, keeping up with the kids. That's what we train for.
People who notice
Miss a session and someone will ask where you were. That's half of why our members keep turning up.
You don't need to be fit to start
Most of our members weren't. Our classes are mixed ages and fitness levels, and every movement has an option that suits you.
