Eccentric Training for fast & lasting muscle growth

Eccentric training without limits at any location: an absolute novelty

In classical muscle training we usually work with concentric movements: The contraction of the muscles, like pushing up a barbell in bench press. Flywheel training with the aerobis kinetic trainer, on the other hand, requires mainly eccentric muscle work: the movement against a resistance, such as when lowering the barbell in bench press.

This works with a rotating flywheel, which should be set in motion in the concentric part of the exercise and then slowed down again in the eccentric part with maximum effort. Through this maximum effort, the deceleration of the resistance ideally occurs faster than the build-up of resistance in the concentric phase. This results in an enormous training stimulus, which is difficult to achieve by other means.

When you train with the Kinetic Trainer you increase:

  • Muscle strength
  • Muscle mass
  • Jumping power
  • Core strength

This is how training with a flywheel works

aerobis Kinetic Trainer is a compact device that can be attached in a flexible way to walls, rigs or pillars. The movement sequence is in two phases.

Phase 1 – Concentric movement: The flywheel inside the trainer is set in motion and accelerated by pulling the strap. It builds up kinetic energy. As soon as the strap has been completely unrolled, the flywheel automatically pulls it back again: like a yo-yo.

Phase 2 – Eccentric movement: The strap is pulled back by the flywheel. The challenge is to quickly bring the rotating plate to a standstill through high resistance. Afterwards the concentric movement starts again.

Once you get used to the movement with the aerobis Kinetic Trainer, you can vary the degree of difficulty individually by the amount of force in the concentric phase and the selected flywheel combination!

Decide for yourself how hard you want to train

No matter if warm-up or maximum muscle growth: You can determine the intensity of your training with the aerobis Kinetic Trainer yourself. The greater the force required to unroll the band, the higher the resistance when the band is pulled back. Unlike training with weights, your muscles are always under constant tension. This increases the efficiency and intensity of your workout!

The individually adjustable intensity makes flywheel training perfect for many different requirements: From top-class sport and sport-specific training, general fitness, personal training to rehabilitation and physiotherapy.

  • aerobis Kinetic Trainer Plates 8 mm: For a higher resistance during the workout you can supplement the two included 4 mm plates with two 8 mm plates. This offers you an even greater variety of difficulty levels. You can combine the plates for kinetic training: 4|0 mm, 4|4 mm, 8|0 mm, 8|4 mm, 8 |8 mm
  • powrlink Fitness Sensor: Make your performance visible with our mobile powrlink fitness sensor. Transmits acceleration and resistance wirelessly to Apple and Android smartphones and tablets

10 reasons for the aerobis Flywheel Trainer

  1. Effective training: The regular change between concentric and eccentric movements on the flywheel guarantees maximum training stimulus.
  2. Individual intensity: The more force is used when unrolling the belt, the higher the resistance when it rolls up again – you determine the intensity of your training!
  3. Adjustable resistance: The weight discs can be easily exchanged. For an even higher resistance, two 8 mm discs are optionally available. They allow a total of five different, individual combinations.
  4. Training for the whole body: Together with Kinetic Trainer, you not only get an aluminium double handle for training your upper body. The included ankle loops are also perfect for leg exercises.
  5. Training for all needs: Thanks to the variable resistance, the flywheel training is suitable for top athletes, personal training, but also physiotherapy and rehabilitation.
  6. Easy to transport: With a weight of only 5 kg and a compact casing, you can take aerobis Kinetic Trainer wherever you want. Train at home, in the gym or outside in the park!

FAQ – the most frequent questions about Kinetic Trainer

What are the resistance levels of Kinetic Trainer?

  • 0.012 kgm² = 1x 4 mm flywheel
  • 0.023 kgm² = 1x 8 mm or 2×4 mm flywheel
  • 0.035 kgm² = 4 + 8 mm flywheel
  • 0.046 kgm² = 2x 8 mm flywheel

What is so special about flywheel training?

In contrast to classic muscle training with weights, both concentric and eccentric movements are performed on the flywheel: Your muscles exert strength through contraction and work against the pull of the belt when it rewinds.
You are constantly in motion and control the resistance yourself – for maximum training success!

Can anyone train with the flywheel?

Anyone can train with an aerobis Kinetic Trainer. The intensity depends on the amount of force required when unrolling the traction band: You can determine it yourself. The workout with the flywheel is suitable for top-class sports and personal training as well as for physiotherapy and rehabilitation.
