Resistance Ratio

The resistance is reactive, meaning the force you apply concentrically is the force you get back eccentrically. Concentric:Eccentric

+80%

Eccentric Overload

Exerfly’s Motorized Technology adds up to 80% more resistance during the eccentric phase, delivering true eccentric overload.

Performance Training with Motorized Flywheel Technology

Accelerate Results

Motorized Flywheel Technology delivers faster developments in strength, power, and muscular endurance than traditional resistance training and traditional flywheel training.

Optimized Training Intensity

The unique combination of eccentric overload and user-defined resistance work together to ensure athletes are consistently training with the optimal intensity, maximizing strength and power gains while avoiding overtraining.

Safely replicate the high loads athletes experience in sport

Train game-speed deceleration and direction changes—safely and effectively.

Train for both high speed and high force demands in one movement

Motorized flywheel resistance enables eccentric overload at both high velocities and high forces—replicating the explosive demands of elite sport while building resilience against injury.

Precision Rehab

Proven Recovery Acceleration

Exerfly’s motorized technology has been shown to significantly accelerate recovery by promoting muscle and tendon repair through controlled, progressive loading.

Reduced Risk of Overuse Injuries

Minimize the risk of re-injury or overuse during recovery with gradual and precise increases in load.
