Train with an ultra-low-friction flywheel. A brilliantly compact Italian-designed flywheel platform with an integrated resistance change system. Introducing INERTIA by LITE® — a favorite of trainers and athletes.

INERTIA is LITE®'s flywheel platform for exercising against resistance generated by the inertia and kinetic energy of a spinning flywheel. INERTIA is composed of a rotational shaft, to which both a rope and a flywheel are attached.

Once the rope is unrolled from the rotational shaft with a concentric action, the inertia and kinetic energy of the spinning flywheel cause the rope to roll up in the opposite direction, requiring the athlete to perform an eccentric action to decelerate the rope and begin a new exercise cycle. If the rope is decelerated in a shorter time than it is accelerated, muscles can be loaded eccentrically for higher training stimulus.

INERTIA resistance increases with exercise speed, so it can be modulated during each rep and accommodate increasing fatigue. It is well suited to sport-specific movements that involve high deceleration forces.

Key Features

• Speed-dependent variable resistance: with the same inertia, resistance varies with the speed of the exercise — the faster you pull, the greater the resistance. During the eccentric phase, INERTIA returns the energy you applied during the concentric phase, enabling eccentric overload.
• Integrated quick-change resistance system — no adding or removing flywheels; slide the colored sleeve over the shaft.
• Rope regulation system to quickly set rope length to the range of motion of each exercise.
• Optimized design for exercises above and outside the platform.
• Cylindrical shaft (instead of conical) for greater eccentric-phase overload.
• Wall guide compatible for open-kinetic-chain exercises.
• Wheels for easy transportation.
