Hi David, first of all kudos for the strenght! squatting more than 300 kg is insane. Since you seem to use also flywheel on the 0.36/0.44, how much inertia do you think is needed for a training stimulus? is it necessary to go so high in inertia or this is just because you are mad strong?
I have two buldging disk in lower back and a bad knee with arthritis. I dont do barbell squats anymore, been doing land mine belt squats and they are ok. Was thinking about getting Squat max belt squat machine. Or pr rack 4000 with squat belt attachment to replace prx wall squat. But now that I see this it looks like I can build my legs with it pretty safetly??
Hi Marco, yes the kBox allows you to train legs in a safe and efficient way. You can read more about health applications on our website: exxentric.com/flywheel-training/applications/health-medical/
man almost bought a squat max md, looking at rhino now looking at this too. I think this is like a c2 rower resistance only one way and the faster you go the harder it gets
It is quite different from the C2 resistance since with flywheel technology you get a variable resistance and a constant tension on the muscles. So with the resistance being variable, you are able to get the maximum effort out of each repetition.
ok so I get resistance both ways going down and up? I have the rhino belt squat which I like a lot bet most of the time it makes my bad knee (arthritis) sore for days. I don't think is the rhino at all. lol but I wonder if this will be easier on my knee?? I see this is useful for people that has no equipment but I already have a nice functional trainer a nice standalone selectorized lat pull down, a rhino belt squat, echo rogue bike and many more equipment. How would this be useful for me?
@@MARCOLOPEZARRIAGA Well technically you only have a opposing force going down, but there is inertia going up. The more inertia there is the slower you go up because f=ma, but then the energy you put into the flywheel going up pulls you downwards ( like a yoyo getting pulled upwards when it reaches the bottom) so then there is a down force and you have to resist it. So in that sense there is only eccentric resistive forces. Whether its easier on the knee probably depends on your specific circumstances and how you apply it. But the flywheel will give back what you put in, .
@@Exxentric Actually, the way I think of it is that pulling faster increases the resistance. Adding more wheels slows down how fast you have to pull to get a given resistance. I guess you are saying that adding wheels increases the resistance for a given speed. BTW, I have one of your Kbox 4 Pros with 3 XL wheels in addition to a full set of the smaller wheels. 2 XL wheels is enough if I pull fast, but adding more slows things down to work on technique.
@@neilpollack3514 exactly! You of course have to play with these two variables (speed and inertia), but ultimately having more inertia (ie more flywheels) will make it harder and thus "heavier". But really good point 💪
@@ryanlen5337 Think about it as gears on a bike. You can either spin really fast at a low gear, or press really hard and slow at a high gear exerting the same amount of force with either gear.
Using the kBox with our Foot Block is a great way to load or overload the eccentric phase of a lateral squat - which can help with both power development and mobility in the full range of motion for side split mobility 💪
A squat with a harness is not even close to a BB squat in terms of muscle activation. It's hard to develop the hip&core strength with the harness. The classic squat works the hips and core a lot if done correctly. The main problem with a harness is the lack of force transmission (slack). And it doesn't work the core/hips as BB squats do. The deadlift works very fine maybe even better with the flywheel because of the accommodating resistance.
Hi Manuel. There are many variations to work different aspects of the lift using bars, grips, belt or harness. If you want to go closer to a barbell squat you can bypass the lumbar band and get a much more axial loading higher up. I also recommend good mornings and front squat variations to work the lower back and hip extension. The higher forces on a maximal kBox squat also compensates for the differences in technique and biomechanics and for sure gives a high muscle activation. To me personally it helped my BB high bar squat a lot. /Fredrik
what about using a belt on hip for squats instead of the harness? don't like harness cause it stills compresses the spine and I have two bulging disk and a bad knee. ok so I get resistance both ways going down and up? I have the rhino belt squat which I like a lot bet most of the time it makes my bad knee (arthritis) sore for days. I don't think is the rhino at all. lol but I wonder if this will be easier on my knee??

it's too much inertia. You don't need that much. If you can't reach a max velocity of 0.5m/s it no benefit. I would be much better tryig to accelerate a moderate load as quickly as possible but with proper form (not like the guy doing squats and being out of position). I don't think anyone needs more than 0.2 kg/m² wich is like doing 150-200kg on a barbell. 0.28kg/m² is like 200-250kg! The best thing about the kbox is that we can focus on the concentric acceleration form 0 load (no pre tension) wich is very effective for increasing rate coding/ rate of force development. But to achieve this the speed has to be higher because the rep duration must be very short. If found that this can potentiate you jumping performance.
@@davidherrera4350 ok. But the velocity is very slow then like a 95%lift? I think with flywheels you can and should use faster speed because it allows you to accelerate through the full ROM. A training buddy also increased his deep squat from 180kg - 200kg just from the flywheel. But we use a different/better device.
@Exxentric I'm confused you say the most important thing about the harness is the length. Then you give sizes for waist not length. If I go by my waist that's not accurate, you need to tell me what length harness I need.
@Exxentric Hi, Anton doesn't look like his waist is 40" . Why is he wearing an XL squat harness? I thought you chose your squat harness based on your waist size. This is very confusing, and then you say the most important thing is to get the length of the harness correct.
@@user-ic1oe4li2i The height is the most important as the waist has an adjustable strap. The Harness our model Anton here is wearing is either a Large or XL as he is around 6"2.
More content around high inertia needed.

This is awesome!!!
I was thinking how to use the kbox to improve mobility and power about sidesquat to improve side split mobility.

I for sure need more than .28kg/m2 I regularly use .38-44kg/m2. helped me get to 335kg squat and 370kg deadlift.

@@m.b.593 we built our own special one.

It's more like the prosquat form proinertial.
Hi, how much inertia is the guy lifting on the kbox. Looks like he has 6 plates attached.
At the timestamp of 0:55, we mention the kBox here hase 3 Large flywheels and 3 XL flywheels which has an inertia of 0.360KGM^2.
