The Power of the Pivot: Why Flywheel Training Can Outperform Weights for Athletic Agility
Executive summary
A systematic review and meta-analysis published in Kinesiology examined the effects of Flywheel Eccentric Overload Training on athletic performance. The review included 21 randomized controlled trials involving 515 trained athletes. The findings suggest that flywheel training can outperform conventional resistance training for several key lower-limb performance outcomes, including change of direction, countermovement jump, and short-distance sprint performance. However, traditional heavy resistance training remains highly effective for developing maximal strength.
When coaches train athletes for performance, the goal is rarely just to make them stronger in the weight room.
Athletes need to sprint, jump, brake, cut, and re-accelerate under pressure. That means strength matters, but so does how quickly force can be produced, absorbed, and redirected.
This is where Flywheel Training becomes especially relevant. Instead of only loading force production, it also challenges the athlete’s ability to control the eccentric phase, the braking component that plays a major role in athletic movement.
The research: flywheel training vs traditional resistance training
The review analyzed Flywheel Eccentric Overload Training, often abbreviated as FEOT, and compared it with conventional resistance training and bodyweight-based training.
Conventional resistance training typically uses gravity-based loading, such as barbells, free weights, or weight-stack machines. Flywheel Training works differently. Instead of lifting a fixed external load, the athlete accelerates a flywheel and then has to absorb the returning force during the eccentric phase.
This makes the comparison especially relevant for sport performance, where athletes constantly need to accelerate, decelerate, and change direction.
Why Flywheel Training is different
Traditional weights are limited by gravity and by what the athlete can handle at the weakest point of the movement. The load remains relatively constant throughout the repetition.
Flywheel Training with devices such as our kBox and kPulley is based on rotational inertia. The harder the athlete pushes or pulls during the concentric phase, the more kinetic energy is stored in the flywheel. That energy then returns during the eccentric phase, forcing the athlete to brake, control, and reverse the movement.
Why this matters for athletic movement
Athletic performance is not only about producing force. It is also about controlling force.
In sport, athletes must often slow down rapidly before changing direction or accelerating again. Cutting, landing, sprinting, and jumping all depend on the ability to absorb high forces and transition quickly into the next movement.
Because Flywheel Training directly challenges this force absorption and redirection, it can provide a highly relevant stimulus for athletes who need more than general strength.
The results: stronger transfer to agility-related performance
The review found that Flywheel Eccentric Overload Training produced significant benefits across several explosive lower-limb performance outcomes.
The clearest advantages were seen in change of direction, countermovement jump, and short-distance sprinting when compared with traditional resistance training. However, flywheel training did not show a significant advantage over traditional heavy resistance training for maximal strength.
Technical performance summary
The findings show that the value of flywheel training depends on the performance goal. It appears especially useful for qualities that rely on eccentric control, rapid force production, and efficient movement transitions.
The biggest advantage: change of direction
The most pronounced benefit of flywheel training was seen in change-of-direction performance.
This is highly relevant for athletes in field and court sports. Changing direction is not simply about being fast. It requires the athlete to brake effectively, control body position, and re-accelerate with precision.
Flywheel Training naturally exposes athletes to this acceleration-deceleration pattern. Each repetition requires force production followed by force absorption, which closely reflects the demands of cutting and rapid directional changes.
The practical shift
The question is not whether flywheel training replaces traditional strength training completely. The better question is where it creates a more specific stimulus. For athletes who need to sprint, jump, brake, and pivot, flywheel training may offer a stronger bridge between strength development and sport movement.
Why jump performance may improve
Countermovement jump performance depends on how well an athlete uses the stretch-shortening cycle. This involves quickly moving from eccentric loading into concentric force production.
Flywheel Training repeatedly challenges this transition. The athlete must absorb the returning force from the flywheel and then reverse the movement with intent.
This may help explain why flywheel training showed stronger improvements in countermovement jump performance than both traditional resistance training and bodyweight training in the reviewed studies.
What about sprint performance?
Flywheel training also showed stronger improvements in short-distance sprint performance when compared with traditional external-load resistance training.
This does not mean flywheel training replaces sprinting. Sprinting remains specific and essential. However, flywheel training may provide a useful supporting stimulus by improving eccentric control, rapid force application, and lower-limb power qualities that contribute to acceleration.
Where traditional strength training still fits
The review also found that flywheel training did not significantly outperform traditional heavy resistance training for maximal strength.
That is an important point. Heavy barbell and machine-based training remain effective tools for developing maximum force production, especially when the goal is to move the heaviest possible load.
For coaches, the takeaway is not to choose one method for every goal. It is to match the training method to the performance outcome. Traditional strength training can build the foundation. Flywheel Training can help improve how that strength is expressed in dynamic, sport-specific actions.
Practical applications: who could benefit?
Flywheel Training may be especially useful for athletes and coaches targeting explosive lower-body performance.
The method is particularly relevant when performance depends on braking ability, rapid re-acceleration, jumping capacity, and change-of-direction speed.
Why this fits Exxentric Flywheel Training
Exxentric systems are designed to help users produce force, absorb force, and control the transition between the two.
That makes them especially relevant for athletes who need strength that transfers into movement. The harder the athlete works during the concentric phase, the more force they must control during the eccentric phase.
This creates a responsive training stimulus that rewards intent and challenges the exact braking and re-acceleration qualities that are so important in sport.

The bottom line
Traditional resistance training remains valuable. It is still one of the most effective ways to build foundational strength and maximal force capacity.
But athletic performance is not only about maximum strength. It is about how well an athlete can apply, absorb, and redirect force in motion.
Based on the 2025 review, Flywheel Eccentric Overload Training appears to offer clear advantages for change of direction, countermovement jump, and short sprint performance. For athletes who need to move explosively, brake efficiently, and pivot under pressure, that makes flywheel training a powerful addition to the performance toolbox.
Key takeaways

- Flywheel training showed strong benefits for change-of-direction performance.
- Countermovement jump performance improved more with flywheel training than with traditional resistance or bodyweight training.
- Short-distance sprint performance improved more with flywheel training than with conventional external-load resistance training.
- Flywheel training did not show a significant advantage over heavy traditional resistance training for maximal 1RM strength.
- The best use of flywheel training is not as a full replacement for strength training, but as a targeted tool for explosive and agility-based performance.
