Flywheel inertial training (FIT) provides an eccentric overload stimulus dependent on concentric velocity and inertial load, but its effectiveness is highly dependent on user technique and training status.

If using a flywheel device, focus on generating high concentric velocity to maximize eccentric overload. Ensure proper technique to decelerate the flywheel effectively. Be aware that results may vary based on your training status.

ModerateQualifiesMEDIUM confidence
the 'intensity' of the ECC phase of the movement when using a flywheel device may be altered by the CON velocity generated by the individual.
