Home / Exxentric® Flywheel
Flywheel.Australia.
The home of Exxentric flywheel training in Australia — equipment, education and elite coaching, led by the country's only licensed Exxentric educator.
Trusted at the top level
Exxentric flywheel systems are used by performance coaches, physiotherapists and elite teams worldwide — across the NHL, La Liga and the Premier League — and by everyday people rebuilding strength and resilience. The same technology, now coached in Newmarket.
What it is
Strength training, reinvented.
Exxentric are the Swedish pioneers of flywheel-based strength training. Instead of fixed weights, their kBox and kPulley use a spinning flywheel that adapts resistance to your strength, rep by rep.
One compact device, 70+ exercises, your whole body trained through ranges most equipment can't reach — never too heavy, never too light.
The science, simply
Why eccentric overload matters.
Every rep has two halves: the lift (concentric) and the lower (eccentric). Traditional weights load both the same — but your muscles are far stronger on the lowering half, so fixed weight always under-loads it.
Flywheel training lets you safely overload the eccentric phase — where much of the real strength, resilience and injury-proofing is built. That's why it's trusted as heavily in rehab clinics as in elite sport.
Why it works
Four reasons coaches switch.
Unlimited resistance
Auto-adjusts from beginner to elite. The flywheel only ever gives back what you put in.
Full freedom of movement
70+ exercises, new ranges of motion, whole-body training from one device.
Perfect reps, every time
Variable resistance means no sticking points — stronger, safer, faster gains.
Train anywhere
The kBox and kPulley Go are portable enough to turn any space into a gym.
Who it's for
Built for people who train people.
Whatever your setting, flywheel resistance drops straight into your existing programming — no new coaching system to learn.
S&C practitioners
True eccentric overload for athletic development, deceleration and return-to-play, without stacking plates.
Coaches & PTs
One device, 70+ exercises — program strength, hypertrophy and conditioning sessions from a single unit.
Gyms & studios
A compact, high-demand station that adds a premium point of difference to your floor without a big footprint.
Performance & rehab facilities
Trusted in elite sport and clinical rehab alike for safe, progressive eccentric loading through full range of motion.
How it works
Start with a package. Build from there.
Every package above is a defined, sensible starting point — not the only option. Add extra flywheels or accessories, drop items you don't need, or combine kBox and kPulley components across packages.
This isn't an online store — it's the start of a conversation. Once we know your space, goals and budget, PrimalThenics will put together a confirmed quote covering equipment, shipping, duties and GST.
Three ways in
Where you start.
Train on it
Experience flywheel training in our Newmarket studio through Primal Warrior classes — coached, and built into real strength and conditioning.
Own one
Buy a kBox, kPulley or LegExx through Australia's official Exxentric partner — with setup, safety and programming support a website order can't give you.
Get certified
Learn to coach it. From flywheel theory and safe solo setup through to becoming a licensed Exxentric Coach — taught by the only licensed educator in the country.
Who leads it
Chris Miller.
One of only a handful of Exxentric Master Trainers worldwide — and the sole licensed Exxentric educator in Australia.
Coaching since 1997, Chris has worked across six Olympic and Commonwealth Games and with elite teams including the QLD Reds, Brisbane Broncos, Australian Wallabies and Western Force.
Having come back from three knee reconstructions and a sinus tumour with neurological complications, Chris doesn't teach flywheel training from a manual — he understands its role in longevity, resilience and genuine physical freedom first-hand.

Beyond the equipment
Education & ongoing support.
Buying flywheel equipment on its own doesn't make it get used well. Every PrimalThenics package comes with the education and support to make sure it does.
- Setup & onboarding — equipment set up correctly and your team walked through it, not just a box on your doorstep.
- Coaching & programming guidance — from Australia's only licensed Exxentric Master Trainer, on how to build flywheel work into your existing sessions.
- Formal education pathways — from foundational flywheel theory through to becoming a certified Exxentric Coach.
- Ongoing access to PrimalThenics — for questions on programming, technique or getting more out of your setup after the sale.
Good to see you
Thanks for stopping by our stand at the show. Everything we had on the posters is below. Pick the systems you want pricing on and we'll pick the conversation up where we left off.
Where to start
Five systems to start from.
These are the setups we take to conferences and recommend most often — examples, not a catalogue. Every one can be added to, trimmed back, or mixed across systems. If none of them is quite right, that is normal: most orders end up somewhere between two of these.
Prices are Exxentric's confirmed Australian figures and cover the equipment listed. Shipping, import duty and GST, and international payment fees are additional, and vary with your location, order size and payment method. We confirm your exact all-in cost in writing before you commit to anything. Exxentric review their pricing roughly every two months.
