Maximum training results, minimal floorspace footprint: introducing the Kratos EVO. We’ve taken the incredible flywheel power and versatility of the original Kratos's patent-pending dual-axis design and modified it to fit an even broader spectrum of training environments—Chris Duffin himself has the Kratos EVO mounted to the flatbed of his truck! The Kratos EVO is identical in function and hardware to the original Kratos, but it does not include the platform that comes with its original Kratos counterpart. Without a platform, the Kratos EVO allows the user to move around the unit completely unimpeded by elevation change. Combine that freedom with the fact that the EVO takes up small amount of floor space—the unit’s footprint is smaller than the diameter of a standard 45 pound plate—and the Kratos EVO offers a ton of flywheel exercise versatility and minimal gym clutter.
IMPORTANT: Due to its minimalist nature, the Kratos EVO must be mounted to surfaces such as concrete, metal, or other similarly durable material. While the Kratos EVO includes basic installation instructions, we consider this version of the Kratos to only be appropriate for customers who are experienced in mounting major hardware to materials such as concrete or metal. If you are unsure of your DIY abilities specific to projects like installing the Kratos EVO, we do not recommend you purchase the EVO unless you are prepared to utilize the services of an individual qualified to install the EVO using appropriate mounting techniques.

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.
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.
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.

My rack bolts to the floor through ~1/2 in. steel 'feet' that are welded to the uprights and extend out ~2 in. Will the rack mountable version work with my rack?
Assuming there are no other obstructions than the 1/2" feet, then yes the rack mount will work.
I have 3/4" rubber mats. Will the Evo be flush after instalation?
The Evo center tube is 1" so 1/4" will extend above the 3/4" mats. With the radius on the center tube the 1/4" is barely noticeable.
Can the Evo be installed/used outdoors?
It depends on the climate and the set-up. The strap will deteriorate with prolonged exposure to UV, like most cloth/nylon items. The bearings won't do well with exposure to moisture, so if it is a humid atmosphere it would not be recommended.
Does the rack mount version still need to be bolted to the floor? Might be missing it but I don't see a clear answer to that in the description/pictures.
Yes, the Evo will need to be bolted to the floor.
