Flywheel Training

Smarter Resistance for Superior Results

Whether you're rehabbing an injury, training for everyday life, or building elite performance, flywheel resistance training adapts to your effort—giving back what you put in. It's resistance that meets you where you are and challenges you to move better, stronger, and more efficiently.

What Is Flywheel Resistance Training?

Flywheel resistance training swaps gravity for momentum. Instead of lifting weights, you spin a flywheel—and that spinning wheel pushes back. The harder and faster you move, the greater the resistance, especially in the eccentric (lengthening) phase. It’s called iso-inertial because the inertia of the wheel stays constant, but your effort changes the outcome.

The Flywheel Training Cycle

1

Concentric Phase – Push or Pull to Spin

You generate force to spin the wheel—activating muscle shortening like standing from a squat or deadlift.

2

Eccentric Phase – Resist the Pullback

The flywheel pulls back. You fight it, slowing the momentum and building strength as your muscles lengthen.

3

Amortization – Quick Transition

At the switch, you pause briefly before reversing direction—mimicking the explosive changes of direction seen in sport.

4

Repeat

This continuous rhythm trains your body to control deceleration and acceleration in one fluid motion—just like sprinting, jumping, and cutting.

Why Flywheel Training Outperforms Traditional Weights

Traditional Weight

Load limited by gravity

Eccentric phase is often underloaded

Variable resistance through range of motion

Fixed resistance regardless of fatigue

Progress by adding weight

Flywheel Training

Load created by inertia (effort-based)

Eccentric resistance is equal or greater

Constant tension throughout full ROM

Continuous, fluid transitions

Adaptive load based on user effort

Progress by increasing force or flywheel size

Why Eccentric Matters

The eccentric phase—when muscles lengthen under load—is where much of the magic happens. Flywheel training naturally emphasizes this phase, helping:

Build resilience and reduce injury risk

Improve strength and muscle quality

Enhance power, control, and stability

Support effective rehab and return-to-play timelines

Built for All Who Move

Whether you're a physiotherapist guiding recovery, a coach refining athletic performance, or someone who wants to move better for longer—flywheel training adapts to your goals.
