Why VOA?

Resistance, powered by air alone

Precisely controlled air pressure in place of mass and motors.

Air resistance

Find your flow. Smoother strength training with Aerokin™ Technology.

What it gives you

Precision progression

As little as 100 g at a time.

Fine resistance adjustments enable more precise progression across different strength levels, abilities and training goals.

Smooth by design

Minimal mass. Responsive movement

Air creates resistance without heavy moving weight stacks, reducing the influence of moving mass and inertia.

Built for speed

Strength. Speed. Power

Minimal moving mass enables responsive resistance across different movement speeds, from controlled strength to high-velocity training.


Shaped by biomechanics

Designed around human movement

Engineered lever geometry shapes resistance through the range of motion to align with the intended biomechanics of each exercise.

Common questions

Frequently asked

VOA machines use air resistance technology called Aerokin™, which utilises the natural transmission of power. Dial in the resistance to match the natural force and movement of the user's muscles to make workouts smoother and more effective.

Strengthspan goes beyond how strong we are today. It's about maintaining the strength and physical capability to stay active and independent, while continuing to do the things we love throughout life.

VOA turns training data into meaningful insight, giving fitness professionals the tools to understand every individual, personalise training and guide progression. Technology provides the insight. Human Intelligence turns it into action.

Lightweight machines with a smaller footprint offer environmental advantages, minimising the carbon footprint while maximising investment gains.
