Frequently asked questions
By listening carefully to the wishes of the customer and by gaining more in-depth knowledge about everything concerning flywheel training, Kynett has expanded its range with various mobile devices and accessories which make training with Kynett even more fun, more intensive and more challenging. Moreover, the production and assembly is all carried out inhouse and is entirely located in the Netherlands.
Flywheel training is a unique development in sports and physical therapy. Training with a flywheel is also called kinetic training. Instead of traditional weights, the training is done with a rotating disc. In the concentric phase, the flywheel starts and accelerates by means of pulling a webbing. When the webbing is completely unwound, so much kinetic energy has now been built up that the webbing will roll itself up again, just like the well-known yo-yo. The goal is to bring the flywheel to a stop and then start it up again with a concentric movement. So the resistance you experience is not caused by gravity, but by inertia, also called mass inertia or (rotational) kinetic energy. The harder you pull, the harder the flywheel will spin and the more inertia will occur. To then brake the flywheel you will need quite some (eccentric) force!
With all of our products, you are able to train your entire body. On the website there are a number of instructional videos. It is very easy to think up and try sport specific exercises yourself, think tennis, boxing, golf etc.
You can easily order via our webshop. But if you prefer personal contact, please send an e-mail to firstname.lastname@example.org
The resistance with which you train is not expressed in kilograms, but in a moment of inertia: kgm2. Every object that can rotate around a certain axis has a so-called moment of inertia. Based on the mass and dimensions of the rotating disc, the moment of inertia can be calculated.
Eccentric training improves strength, speed, power and performance related skills such as jump height and running speed to a greater extent than concentric or traditional training. But what do we mean by eccentric training and eccentric overload? Lifting a weight with your biceps is a good example of a concentric movement. Your muscles become shorter and therefore lift the weight to the ceiling. As you lengthen your muscles again, the weight returns to the starting position. Lengthening the muscles and thus lowering the weight is called an eccentric movement. It is possible to make an eccentric movement without much force. For example, by lowering a lightweight dumbbell. However, when we talk about eccentric overload, we are not talking about a movement with a light weight. A movement contains eccentric overload when you produce more force in the eccentric movement than you can produce concentrically. In practice, this often means that you lower more weight than you can lift (> 1RM). Therefore, lowering a weight slowly causes no eccentric overload if you could also lift the weight. It should come as no surprise that slow eccentric movements don't produce the same positive results as true eccentric overload like flywheel training. Flywheel training exercises are also more multifunctional, because at the beginning of the eccentric phase, you have to slow down and stay balanced. This will train more muscles (including your abdominal muscles) and improve your balance. Training with Kynett is suitable for many target groups such as top sports, rehabilitation, physical therapy, personal training, fitness and sport specific training. Training can be both light and intensive, and focused on speed or power.
The production and assembly of the Kynett is done in-house with modern production equipment and is entirely located in the Netherlands.
The Kynett HOME makes flywheel training affordable and easy at home. Due to the compact and durable design, the Kynett HOME takes up almost no space. The weight of the resistance is determined by means of resistance discs. The Kynett HOME comes standard with two 4 mm thick discs. Lighter resistance discs of 3 mm or heavier discs of 5 mm can also be used. A maximum of one disc per side can be used. The discs can be combined, but you can also train with one disc. This way you determine the intensity of the training yourself.
The Kynett FIT is made from durable and sturdy materials and comes with a steel support and two ratchet straps, so you can train wherever you want! With this innovative way of training, all muscle groups can be trained within 1.5 square meters. The Kynett FIT comes standard with two 4 mmthick resistance discs and offers the possibility to train with heavier resistance than the Kynett HOME. Resistance discs of 2, 3, 4, 6, 8, 10, 12 and 15 millimeters are compatible with the Kynett FIT! The Kynett FIT can also be attached on the wall with the mounting set.
The Kynett PRO is made from durable and sturdy materials and comes with a solid wall mount. This makes the Kynett PRO very easy to adjust to different heights and the possibilities are endless. With this innovative way of training, all muscle groups can be trained within 1.5 square meters. The Kynett PRO comes standard with two 4 mm-thick resistance discs and offers the possibility to train with heavier resistance than the Kynett HOME. Resistance discs of 2, 3, 4, 6, 8, 10, 12 and 15 millimeters are compatible with the Kynett PRO!
The most complete and extensive set in our range! With this multifunctional wall setup you have everything in one! The innovative design makes it possible to switch between upper and lower body in no time. The pulleys at the top and bottom make it possible to perform all exercises within a range of 1.5 meters, which results in an enormous space and cost saving compared to renting/ purchasing expensive fitness equipment and large spaces. In addition, the Kynett ULTIMATE offers the possibility to train with heavier resistances than the Kynett HOME. Resistance discs of 2, 3, 4, 6, 8, 10, 12 and 15 millimeters are compatible with the Kynett ULTIMATE!
