The Kynett Fit flywheel trainer is something I’ve been very excited to try.
Prior to getting the Kynett Fit, I had never done any flywheel training so I wanted to see what the hype was about.
Flywheel training uses kinetic energy transferred to a flywheel (think of it like a yo-yo).
This puts a big emphasis on eccentric overload (negative part of the exercise).
So the harder you pull on the cord, the harder it wants to pull you back forcing you to control the negative.
Let’s check it out!
Unboxing
Table of Contents
First thing I see when I open the box is a 4mm resistance disc (flywheel).
There’s two flywheels included.
Right below the resistance disc there’s a plastic housing where you insert the resistance discs.
What’s Included?
Here’s everything that’s included inside the box of the Kynett Fit flywheel trainer:
- Strap length adjustment attachment
- Multi-function handle
- (2) Crossfit handles
- (2) Fastening straps
- Ankle cuff
- Disc housing
- Universal bracket
- Carabiner
- Wall mounting hardware
- (2) 4mm resistance discs
Disc Housing
The disc housing is where the resistance discs lie.
And just like a yo-yo, there’s a cord that attaches to the middle of the wheels.
When I open one side of the housing you see there’s a grey knob in the middle.
This is what keeps the resistance disc secured to the center of the housing.
And here’s what a resistance disc looks like once it’s on.
All that’s left is putting on the knob to keep the disc in place.
Put the knob in the center and tighten it.
Then you do the same on the other side.
Here’s a bird’s eye view of the disc housing with both sides open.
Resistance Discs
The Kynett Fit comes with a 4mm resistance disc.
A resistance disc’s weight and diameter determines the maximum resistance it can generate.
The bigger the number on it, the harder the workout can get.
Kynett Fit can work with heavier resistance discs up to 15mm.
Universal Bracket
The universal bracket can be used on many surfaces.
You can see there’s 4 holes on the bracket if you wanted to attach it to a wall.
The back of the bracket has rubber pads that help to protect whatever surface you have it against.
I wrap it around my PRx performance rack and that’s what the fastening straps are for.
You can also use the straps to anchor the Kynett Fit around a tree, column, or any other post-like structure.
Here’s the top of the bracket against my rack with the strap holding it in place.
The bottom of the bracket is set up the same way.
Handles
Kynett calls these two handles “Crossfit handles”.
They have rubber grips and 3 D-rings on each strap.
The D-rings give you the option to make the strap shorter or longer by clipping it on to the carabiner on the flywheel strap.
The bigger handle is the “Multi-functional Handle”.
This one has a longer handle and also connects to the flywheel’s carabiner.
And the last handle attachment that comes with the Kynett Fit is an ankle cuff.
Self explanatory, wrap it around your ankle for lower body exercises.
Strap Adjust
The strap adjust make the flywheel’s strap shorter.
This strap is helpful for exercises that require adjusting the strap length.
What Is Flywheel Training?
Flywheel training is a type of resistance training where the resistance is generated by the inertia of a flywheel instead of weights and gravity.
Contrary to weight training, flywheel training has variable resistance.
The concentric part of the movement is easier than the eccentric.
Because the concentric portion of the movement is harder, it’s been shown to be a good training style for hypertrophy.
How Does Kynett Fit Flywheel Trainer Work?
The Kynett Fit flywheel trainer comes with a universal bracket that can be mounted to a post, wall, or tree.
Once the flywheel is anchored securely, all you do is attach the disc housing.
Then select the type of handle you want to use and you’re ready to start working out.

Pros & Cons
Pros
- Portable: Can be used indoors and outdoors. Just wrap the straps around a pole, weight rack, beam, tree, etc.
- Adjustable: Change be moved up and down to change angles and perform different exercises.
- Variable resistance: The harder you pull, the harder you have to resist the flywheel pulling back.
- Space saving: You don’t need much room to get a full workout
- Versatile: The amount of exercises you can do with a flywheel are endless.
- Accessories: Can be used with a squat harness, handles, straps, ropes, platforms, and more
Cons
- Learning curve: It takes a little bit of time to get used to the pull back from the flywheel but the more you use it, the easier it becomes.
Flywheel Training Exercises
The amount of exercises you can do with a flywheel trainer are endless.
You can anchor the flywheel low, middle, or high and do anything you want with it.
Kynett Fit Flywheel Review
Flywheel training is different than anything I’ve ever done in the past.
It’s like a tug-of-war with the flywheel and the harder you push/pull, the harder it pulls you back.
This is why it’s called an eccentric exercise machine by many, because you’re forced to control that pull back.
The Kynett Fit does a great job at giving you that eccentric overload.
I also like that I can move it up and down my rack to change angles and do a variety of exercises for both the upper and lower body.

Thanks for the review. The coupon code SHREDDED is not working.
Hey Justin, sorry about that.
I’ll message them and see why it’s not working.
Ok Justin, they just fixed the issue and the coupon code SHREDDED is working again. Click here to get to the site.
Great, thank you
Hey coach, I travel a lot so I’m looking for something that can help me build strength and muscle while having no access to a gym. Is the kynett capable of that?
Flywheel training focuses on the negative portion of exercises (eccentric) which is good for both strength and hypertrophy.
It’s not like a regular cable machine where you get equal resistance on both ends of the exercise.
The goal with a kinetic trainer is to slow down the eccentric portion.
So to answer your question, yes you can build strength and muscle.
You just have to get used to the way it works.
Thanks for the review! Just wondering if you’re in the USA and if so, were you charged any importation cost like brokerage fees and duties, and approximately how much? The Kynett site says they ship from Netherlands via UPS (Worldwide Standard).
I am in the U.S. and no, I didn’t have to pay any import fees but that can vary from state to state.
Hi. Do you think this can replace a traditional cable system, such as a single tower or functional trainer? I have adequate space. So considering all things equal, would you go with a Kynett over one of the other options?
If you want to train more eccentrically and explosively, then a flywheel would be a better option than a cable machine.
For example, when I do bicep curls on the flywheel, I can curl with high force but I have to work harder to prevent the pull back from the flywheel.
Hi. Just curious if you think this can replace a traditional cable machine, such as single tower or functional trainer. Space really isn’t an issue with me but I like the versatility.
It’s different than a traditional cable machine. You can do similar exercises but the forces on flywheel are different than the constant forces on a cable machine.
With a flywheel the harder you pull, the harder it will pull back so it’s more eccentric based.
There seems to be some plastic housing around the discs. Do you think the product will last? Also, have you compared it with any other flywheel training devices?
The housing is plastic but I don’t feel like it matters. It’s not getting banged up constantly while I exercise.
Hi,
Thanks for the review!
I’ve seen some flywheel systems, like the Handy Gym, which are very loud. How loud does the Kynett get? As a dad like you, I’m looking for something that won’t wake up the kids if i train at night.
Also, if you had to choose, Kynett or 2 Ancore Pros? 🙂
It’s not loud at all so it should be safe for the kids to stay asleep.
The Ancore Pro is different than a flywheel.
Ancore is more like a cable machine where you can concentric and eccentric resistance.
Kynnet is more eccentric based, the more force you put into it the harder is pulls back.
If you’re on instagram and want to hear how Kynnett sounds, feel free to send me a DM @dadshredded and I’ll shoot a short clip
True. I’ve been looking at both. Similar but very different at the same time.
But if you HAD to choose one.. which one do you find yourself drawn to most often, or which one do you find most useful?
And thanks, I’ll DM you right now.
It all depends on what the workout calls for honestly. I have two Ancores so if i need to do cable crossovers or flys then that’s my go to. Also like them for side lateral raises and reverse flys.
I like the Kynett when doing cable curls because it forces me to fight the negative and the burn and pump is insane on my biceps.
Also like the flywheel for squats when using a squat plate. The squat plate has a pulley below me so it’s almost like doing belt squats.
Does the Kynett fit provide eccentric resistance throughout the entire lengthening of the muscle or is it like a short burst of eccentric resistance?
You get eccentric resistance the entire way
How does this compare with the KPully2?
I’ve never used the KPulley2 so I can’t compare it to Kynett’s
What disc sizes do you recommend.
Were you only using the 4mm disc’s. Is there sufficient resistance or did you need heavier disc’s. What would you recommend buying.
I have the 4mm discs and also have the force extender which doubles the resistance of those discs.
Sorry last question, do you find that gives you sufficient resistance for upper a d lower body work. You do look like you are putting in serious effort. Last thing, how has it held up. Thanks again for your reviews.
Yes it does and the main thing with flywheels is the eccentric portion of the exercises so I’m working on resisting the pull back more than anything.
It’s different than a regular cable machine where the harder you pull/push, the harder the pullback.
It still works well.
Thanks for the great review. Seems that the coupon code is no longer valid?
Had someone mention the same thing so I reached out to Kynett and they say the code is valid for orders above $449.
Just tried to order something over 700 bucks, the code didn’t work. 🙁
Alright, let me message them to see what the issues is and I’ll get back to you.
Hi, thanks for the review, do you know if you can use only 1 disc or 2 discs of different sizes to get different resistance profiles? I’m considering buying a Kynett and am trying to figure out how many and which discs to buy.
Hi Richard, you can use discs of different sizes. They just can’t be stacked.
