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.

"Exerfly continues to provide high quality flywheel training products and still stands superior to the rest by featuring the eccentric motorized technology. One thing is for sure, the eccentric motor serves as a way to avoid underloading a very important phase of movement that is critical to success in sport."

Chris Chase

Former Director of Performance at Memphis Grizzlies

"The Exerfly experience is second to none. Flywheel training is a unique modality that cannot be replicated with any 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 RackFly 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."

Jan Seiler

Strength Training Expert at the Swiss Federal Institute of Sport

“The Exerfly flywheel has been a great addition to our weight room this year. It’s given us the ability to load quicker eccentric contractions, work on reactive strength, and also dose hypertrophy training. We’ve used it both as the main stimulus for certain movement patterns as well as a faster contrast stimulus for certain patterns such as bilateral squats. It gives us options that other equipment in our weight iron is unable to do.”
