Why flywheel training
Strength that adapts to you.
Pull, and the flywheel spins up. Brake it on the way back. Every rep loads both directions – the way physiotherapists and Olympic athletes train.
Small device. Serious training.
Up to 70 kg / 154 lbs
Heavy enough for athletes
Controlled enough for rehab, heavy enough for elite athletes. Your force sets the load.
7.7 kg / 17 lbs
Aluminium, made to travel
A strong aluminium housing that goes from the gym to the field and back.
Made in NL
Built to last
Engineered and assembled in our own workshop in the Netherlands.
How it works
Three steps. Every rep.
You pull
The strap unwinds and spins the flywheel. Pull harder and the resistance rises with you.
It stores your energy
At the end of the movement the strap rewinds, carried by the energy you put in.
You brake it back
Slowing it down loads the lowering phase – eccentric overload, where strength is built.
Set up in minutes
Your gym, wherever you hang it.
Strap the FIT to a rack, a pole or a tree with the included bracket set, or fix it to the wall with the Wall Adjust for FIT. No plates, no weight stack.

Customer Reviews
Overall rating: 4.9 / 5 from 16 reviews.
Like the dual flywheel setup I have for Great Chest workouts . Chest Flies & Presses !!! Not too bad for a 68 Year Old !! Flywheel training has given me renewed dedication to Training with minimal Joint stress
The design is good, easy to use and it is made from quality material. It comes with a lot of accessoires. I love that one can use different mounts so all needs can be fulfilled. The fact this equipment can be heavily loaded is a big plus for me. Hopefully they make more compatible disks with heavier loads then the current ones
The difference with Home model give a really gap difference to increase the different level weigth. Amazing
Mazing addition to the gym! Great tool. Strong, classy looking. Its awesome!
100% Best Training Equipment Purchase I have ever made!!! Replaces a whole cable machine functional trainer and takes up zero space, yet gives a better workout, and I received in 3 days after purchase while dealing with awesome customer service. Question: would you like to do a skierg and rower style workout in the same machine, but also use it for squats, curls, abs and lower back, chest flies, and much more? Then the Kynett is what you want! Here is my honest review without the sugar-coating. Here's my novel. My name is Joe. I am a U.S. Navy Special Operations Veteran, a former D1 Wrestler and MMA Fighter and Coach. I've had 9 surgeries mostly in my shoulders and feet, and countless other injuries. Despite this, I am still strong at 43 years old and very active. I am an avid surfer. For strength training, I have done it all and had some pretty stellar professional strength influences and coaches. Long ago I discovered that typical weight training became a bit monotonous, and about a decade ago I really became fascinated with unilateral training after years of shoulder issues. I performed very unique exercises during physical therapy. Subsequently, I started incorporating similar exercises into my workouts when I was in good health. I really got into kettlebell training about a decade ago and found the ability to do cardio, strength, flexibility, muscle memory, agility, vestibular and durability training all at the same time. However, with more procedures I needed to be able to isolate muscle groups better with less impact on my body, and I really wanted to target the eccentric phase of training (something we all tend to neglect). I stumbled upon Kynett, and all I have to say is, WOW! I was able to get the same benefits as kettlebell training, but even better!. The Kynett flywheel does so much more than what I was expecting. I didn't know what to expect. I thought it might be too easy, and I was pleasantly surprised. I'm 6 ft Tall and 230 pounds, and this little thing that fits on a single wall stud, is portable with the ratchet straps, or fits on my squat rack is a BEAST! But it is only hardcore if I want it to be. While in the middle of a set I can changeup to a lighter more cardio-oriented workout, an intense, explosive exercise, isometric or plyometric workout and more while in the middle of cranking out repetitions. I was pleasantly surprised to find that I was soon doing HIIT Workouts (High Intensity Interval Training) in the same way I do kettlebell complexes. The difference is, that the Kynett pulls back. Therefore, for the first time in my life, I felt the intensity I used to feel on the wrestling mat with an external force working against me as if there was an opponent standing against me. It just makes training have so much more efficacy. Then, I use it to train my injuries and keep up with physical therapy where I have ongoing issues. Internal/external shoulder rotations on the Kynett flywheel is quite impressive and is way more efficient than using resistance bands. On a down day, or when I'm hurt I can get a stellar workout without the strain, and really target my injuries when needed. I even bought a sit down rower and do long 30-45 minute workouts with it. Let me tell you this thing blows away a typical rower. I also use it like a Skierg (ski workout), and its even more intense if I want it to be. I can load up 15 mm Plates and a Force Extender if I want to have a heavy load with larger muscle groups. Since I'm creative, I can install pulleys on the floor, ceilings and walls to get 90 degree angle changes (haven't done that yet but looking forward to it, but I do have the squat plate that does all that already). The Kynett can completely replace a Functional Trainer (Cable Machine) with zero stacks of weight and taking up none of the space. This keeps my garage spacious! I thought initially I would get 2 Kynetts in order to do Chest Flies...No need! The TRX-style, two-handled straps means one Flywheel allows for two arm use. I have a lot of exercise equipment, but the Kynett is definitely the most versatile piece of gear I have. I can not recommend the Kynett enough! My personal recommendation is to get the Kynett FIT, which is going to give the broadest range of resistances. I have the HOME as well, which is great for portability and taking outdoors. It is perfect for most things, but I like to go heavier and have more versatility. Here's another recommendation: try it several times before final judgement. I found it a little strange at first, but every time I used it I loved it more. I just had to get use to it. So expect a little familiarization time. To get started just adjust the strap close to where you want to stand in the room, then start pulling. Once the flywheel is moving, I move forward or away from the Kynett in order to find my full-range-of-motion (with small steps) without it snapping back too early, and so the strap always remains taught. Bottom line: the Kynett is AMAZING! I know I made the right decision now that I'm reading some of the peer-reviewed scientific and medical information on eccentric, flywheel-based training. This is even more the case having seen the price points and lack of flexibility on other flywheels brands. The Kynett is the next big thing in the fitness industry! I recommend it to all genders, ages and fitness levels. A big hulking power lifter could walk up to they same flywheel with the same disc size and get the same quality workout as an elderly woman with orthopedic issues. You get out what you put into it. Lastly, the Kynett Customer Service is stellar. They answered all of my exhaustive questions. I'm writing this so that maybe I can answer some of those same questions for you. I ordered from Virginia Beach, VA in the U.S. I received all of my items in only 3 days even though the packages came from the Netherlands! Shipping was free too. The squat rack mount works great on my REP Rack. I'm so stoked about this and find myself doing more flywheel exercises than anything else. However, I still supplement with the same exercise equipment I did previously. Some workouts I like better than others and some I just stick to my previous training. You just have to find what suits you. Having the Kynett can be a whole gym on its own (especially if space is an issue), or you can add it to your commercial or home gym setup.
Less of a eccentric loader more of a anti concentric loader. Pedantic difference but important distinction. It will not replace a slow heavy free weight, but its a unique enough feel that there will be plenty of adaptation to get out of it. Game changer for shoulders. Very impressed.
The flywheel is awesome! It replaces entire pulley system in my home gym. It requires a little bit of practice in order to learn how to do exercises with eccentric overload, but once you learn it it's a blast! I recommend to buy additional disks right away if your stronger person, but even with the stock ones you can overload vast majority of movements.
EVERYTHING has been wonderful! The service, the equipment, delivery! I'm in the US and we can NEVER get the on time, early, updates like you have delivered! So appreciated! Your online work outs and instructions are phenomenal! Can not say enough good things about your company and equipment! Thank you!!
What an incredible device!! I’ve started adding it to my regular lifting workouts as a finisher but also as a standalone workout! Can combine exerises and make it a cardio workout as well. Really nice, durable product.
A great addition to my home gym..so much I can do with it..
I do like the product and enjoy the training with it
Great product . So many different exercise options !!
its a really good setup; no problems getting started.
I am having huge success with the flywheel which I wanted to share. I am 34 and have been training since I was 16 without gaining much muscle as I am quite a skinny body type. However, because the flywheel is so incredibly efficient for every rep, I am gaining strength and muscle faster and more effectively than ever before.
The Kynett FIT Flywheel is a game-changer, and I highly recommend it to anyone looking to enhance their home workouts. Its compact size makes it suitable for all types of spaces, and the package includes clear instructions and all the necessary training accessories to get started with flywheel training. In a short training session, you can engage multiple muscle groups, and you can perform a wide range of excercises with this device. The Eccentric resistance by this training device is very explosive and effective, this training device is a must-have for fitnesss enthusiasts!
I love training on my Kynett Flywheel trainer. It is a demanding workout and different from anything that I've ever used before. It has become a integral part of my fitness routine.
Where can I mount the FIT?
On a rack, pole or tree with the included bracket set, on the wall with the Wall Adjust for FIT, or in a power rack with the Rack Adjust.
What's the difference between the FIT and the PRO?
Same discs and the same training. The FIT is the portable version: light, aluminium and easy to take along. The PRO is a fixed station on a 166 cm / 65 in wall adjust, made for daily use in clinics and gyms.
Is it suitable for beginners and rehab?
Yes. The resistance follows your own force, so it suits every level – from first rehab session to professional athletes.
How much resistance do I get?
Up to 70 kg / 154 lbs with the included 4 mm disc set. You set the load yourself: the harder you pull, the more resistance you get. With one 4 mm disc it starts around 20 kg / 44 lbs, and the 15 mm disc set goes up to 200+ kg / 440+ lbs.
How fast is delivery, and do I pay import duties?
UPS, usually 1–4 business days. Within the EU there are no import duties; for US orders Kynett pays all duties and import taxes.
What if it isn't right for me?
You can return it within 30 days.
