Case Study

Real-World Results: Braking Force
and mRSI Improved in 5 Weeks

A 5-week case study using Exerfly’s motorized flywheel squat protocol showed measurable gains in key explosive performance metrics. By delivering a powerful eccentric overload and enhancing the stretch-shortening cycle, athletes improved their ability to decelerate, absorb force, and explode upward—all crucial for sport-specific movements.

Escape the Gravity Trap of Traditional Resistance

Traditional weights rely on gravity, creating dead spots where resistance weakens. Flywheel resistance training eliminates these gravitational dead spots, providing constant, adaptive resistance throughout the entire movement. This ensures continuous force production and maximizes neuromuscular adaptation, driving superior performance at every phase.

Weaponize Fast-Twitch Fibers

Explosive movement starts with fast-twitch fiber recruitment—and Exerfly is engineered to target it.

With resistance that dynamically overloads the eccentric phase, Exerfly stimulates high-threshold motor units that conventional weights often miss—resulting in stronger, faster, and more reactive athletes.

Eccentric Overload. On Demand.

Our Motorized Flywheel Technology introduces an unmatched training stimulus—actively increasing eccentric force output to drive superior adaptation. This enables, precise, safe, and true eccentric overload training.

Allows for both high speed and high force eccentric overload

"The Exerfly experience is second to none. Flywheel training is a unique modality that cannot be replicated with another other modality of training.  For a coach who primarily works with team sport athletes we prize deceleration capabilities as high, if not higher, than speed.  Doing intense deceleration training can lead to soreness, impair recovery, or conflict with a competition schedule. The Exerfly accommodates to our athletes output on a given day and has been quicker to recover from leading to better results, faster, even with a congested calendar."

“Having Exerfly at our facility was the best to help our athletes improve their performance, easy to use, amazing customer service and the results are real.”

“I think flywheel training with the Exerfly Rack Fly is a great way to train the trunk and core. It challenges the athlete to a greater degree than when performing the same movements using bands or a cable machine. The uniqueness of the loading helps get more out of even basic exercises like rows and rotational exercises.”

“The reason why I like using Exerfly in training is the gains are so much faster than traditional lifting and you get immediate buy-in. It is more engaging and fun for the typical client because they are learning something new, it's not your typical squat, core, or rowing exercise.”

“How can I prepare my athletes with high forces without jumping? I found that flywheel, especially Exerfly and its motorized technology was the best way to do that."
