Hypertrophy Training

There are many pathways and strategies for stimulating muscle hypertrophy. Of them, mechanical tension, total volume, and metabolic stress are the primary catalysts. The Kratos excels at stimulating metabolic stress under high mechanic tension making it an unconventional yet effective tool for hypertrophy training. The Kratos may be used as a standalone device however it can be a formidable 1:2 punch when combined with traditional barbell, dumbbell or machine training. Traditional methods of training emphasize concentric muscle load to produce an overloading hypertrophy stimulus whereas the Kratos provides an overloading eccentric muscle load. Combining these two types of muscle loads will provide a much greater stimulus than if you were to target a single type.


Sport Specific Strength Training

One unique application of the Kratos is in grappling sports such as wrestling, and the various subdivisions of MMA. Combat sports require athletes to resist movement of an opponent. At the physiological level this movement resistance is translated as isometric/eccentric muscle load. Resisting the force of an opponent can be simulated on the Kratos through the overloading action of the flywheel. In practical terms the stored energy in the flywheel feels like a constant force pulling on your body while you are performing exercises. This is far different than a standard cable machine or free weight implement where the load is static.

An emerging area of study for eccentric overload training is teaching movement deceleration. Deceleration is a primary component to agility and change of direction for field sport athletes. The Kratos may also influence post activation potentiation (PAP) by providing a significant neural response during eccentric overload. Overloading this phase of movement may prime the nervous system before jumping, bounding, or doing other explosive type exercises. This neural priming allows users to express greater power output when external load is removed.



The ability to change the intensity of the Kratos without having to switch between different machines, bars, or weights makes it a perfect candidate for applying time under tension training techniques. By using variable load management, you can effectively perform very hard total body exercises over a longer period of time. To do this with traditional implements you would need to combine different dumbbells, bars, or machines to effectively scale load. The benefit of the Kratos is the ability to sustain continuous work without taking time to transition to different implements or weights. This will lead to higher training density which should be a primary goal of anyone who wants to improve their conditioning. Greater training density ultimately means your time in the gym will be spent efficiently.


Rehabilitation and Recovery

When it comes to exercise intervention during rehab and recovery scaling load is one of the first variables strength coaches and clinical experts will adjust. A unique advantage the Kratos has is letting the user adjust load based on effort and how challenging they feel the stimulus is. This is more of an agile approach to scaling exercise load than traditional fixed training implements such as barbells and dumbbells. Specific case studies involving lower back injuries show benefit of the Kratos to re-introduce load by limiting the total axial force through the spine. Other unique strategies include reintroducing load to tendons without relying on excessive amounts of concentric muscular action. Because the Kratos overloads the eccentric portion of movement users are able to target connective tissues post injury with much higher eccentric loading than would be possible with barbells, machines, or dumbbells.

    Can't use it due to missing floor peace!

    Waited over 3 months for an in-stock item and when it arrived I had no floor mount and no clue if it will ever come. ((Paid over 3k for the set))

    Instructions on the Kratos website are very unclear and I don't have the floor mount as shown in the manual - I don't even know if I will ever get it or if it exists in my order, as there isn't a proper items list.

    Furthermore there isn't any phone for support on the Kratos website.

    I will review the item again, when I get all the pieces!

    Feels Underdeveloped and Unowned

    Underdeveloped: All the 3-D printed components have some delamination. The cam in my opinion is upside down. The webbing pulls on the cam’s metal flaps increasing the probability of fraying, cutting, and sudden and complete failure. The clamp for the flywheels should have a rotational lock feature like Olympic barbell clips. The clip detents allow for plate wobble there should be rubber gaskets to reduce the severity. The pully should have a brake in the event impact between the pully and the sliding webbing guide occurs. The ultimate upgrade in my mind is for the wood platform to be on sturdy adjustable stilts or a frame. The fly wheel subsystem could hang beneath the platform for larger range of motion while on the platform. Or a sliding platform connected to the metal frame which elevates the user and allows for platform removal. I recommend sourcing Kevlar webbing. Kevlar is expensive but again safety should be a high priority when dealing with high tension, high energy, rotating systems.

    Unowned: The logistics of assembly and delivery felt like there wasn’t much care. Not all the bolts were tight on the platform or the inertia subsystem cover when delivered. The assembly hardware wasn’t delivered with the system. The holes in the platform didn’t line up with the holes in the inertia assembly.

    I hope Kabuki Strength continues to improve the design as I believe it has the potential to help everyone perform power movements.

    Didn’t come with all the hardware for minimum use, 3-D printing enclosure needs work

    The device didn’t come with the necessary hardware to start using it. I expected more from a device of this expense. The enclosure near the fly wheel is delaminating and makes me question the other 3-D printed components. I’ll update as the issues are resolved or explained.

    KStarr here. I had a chance to play around and use the Kratos unit thanks to my good friend Chris Duffin sending one down via the inventor Wes, who dropped it off at our facility (some of you may have seen it on TheReadyState insta).

    It’s an exceptionally crafted piece of equipment that looks good in any setting. The oak floor is gorgeous! Applications are endless not just in terms of movement variety but use for conditioning purposes, rehab, time under tension training, and of course strength development.

    It’s versatile in that you can slap on pretty much any common gym attachment and find a movement or use for it. Of course, the big feature is having a horizontal option in the same unit and not just being limited to vertical. This opens up possibilities for fighting and other dynamic, upper-body dominant sport applications.

    Awesome product, huge fan. Check out my channel for more videos with Kratos.
