I just bought the Kbox4 Active. There is definitely a learning curve but it is insane. I love it. Its nice to add this to my regular weight training for some variety.

There is one at my local gym and it is awesome for squats. In particular since I have a bad knee and can’t take heavy loads at full flexion, this machine has been very helpful. I want one myself

I did squats on this with my physio therapist, incredibly hard! Love it!

I've been using mine consistently for over a year and it really does make you a lot stronger. You may not see massive increases in the amount of weight you can lift on traditional machines or barbells, but you can tell that you are just way stronger over all on all kinds of movements. Would highly reccomend that you add this to your routine, even if you go to a commercial gym. When people tell me they have no room for a home gym I really do wish I was rich cause I'd just buy them a kbox.

@Garage Gym Reviews Pulling the trigger on this one and some kabuki merch. Coop thanks for all the great reviews love this channel as a fellow garage gym enthusiast. what do you do for a living? prior to youtube and review success ...

Hello mate! one question, you would prefer the exxentric brand belt or with a regular weighted belt would be okey? thanks!

Really good review. Do you still use the machine consistently?

Nice review as always Coop. I just bought a Rogue butcher sled from a guy on CL who swears by this thing. Says he uses it for everything and is selling off all his other equipment. Looks well built and hard as hell. Little bit too pricey and "new age" for my taste though. Keep up the good work bro!

I see you putting together a Coop flywheel power rack. Top, bottom, back, left and right. With adjustable pulleys on the sides to have funtional trainer capabilities.

Will this replace my rhino for belt squats? I ha e a bad k ee with some artehitis do to sports.

The cleanest mustache and review ever.

how is the relation of inertia to weight in you opinion. I mean how much inertia is like doing a 315lb squat?

What do you think about the Exerfly Portable??

Video quality is legit! Green screen background? Looks sharp and clean 💪🏽

What determines adding flywheels to the Kbox? phil

Anyone know where to get a DIY vid for one of these?

Very cool! That said, I'm soooo glad I bagged an original VersaPulley (with platform) for $500.00

I appreciate this review! Read some studies, bought my own for my home gym. I just don’t believe in home gyms anymore and I love squaring love leg day (2-3x a week). Likewise I want what will replicate what I can perform in a gym. I’m ready to get this going when I move in my own apartment next week!

So it has a resistance kindda like the c2 rower

Do you still use yours? @Coop

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??

Will this replace my rhino belt squay?

rhino, squat max md or this flywheel for belt squats and I guess other exercises

Keep the stache, change is always good. Thanks for the video it was... odd/different/a good thing. At 7:02 of the video were those urethane bumper plates over your left shoulder? if so, can you tell me which brand were they and your thoughts on the plates?

Simple and looks very effective...Something you can take with you to the trailer or cottage for a workout... Imagine adding a generator to the flywheel and charge a battery bank so you can charge your phone! That would be great knowing your workout charged your phone or other electronic items. I may just build my own in my shop😁

Great review, Coop! Having been a S&C coach for almost 30 years, it's great to see some of our tools of the trade be available in the garage gym space. This is the one tool I still covet for my garage gym but can't decide between a horizontal or vertical force vector setup. I'd love to dialogue with you a bit in the future about some ideas. Do you a good email I can reach you with?

One of the local gyms recently got one

What about versa pulley producers ? It can be for squats and other moves.

Training with barbells is necessary so that you can track and maintain consistent progressive overload.

Great idea, but I'll wait for a price reduction.

Coop, I have decided to pull the trigger and get one of these. How does this work for belt squats? Is it worth also purchasing the Squat Max MD?

Mustache crew checking in. Cool video! Weird, but cool.

How did no one give Coop props for the Gucci Mane reference?

Lol when the ad for this video was your Prx video

This episode of Better call Saul is great

Coop, is it possible to build muscle on this? I ask because the Nordictrack magnetic resistance flywheel inertial training has a similar concept, but in a marketing launch video Nordictrack mentioned that it was only effective at toning and not building muscle.

Can you do a review of different deadlift bars??

а почему на эксцентрике два конца шнура?

So it's a big yoyo am i right

Can you tellme the thickness of each disc ? To build my own ?

For the price i ll buy a functional trainer anyday😁 by far more versatile and cool looking 😎

Looks cool and the physics behind it is also very cool but man it’s pretty pricey.

Looks like an awesome piece of equipment, but couldn’t justify spending twice as much on this then I did on my power rack.

I wish I would have seen this video before loading up my garage with $25k+ worth of gym equipment...plus I could have saved a ton of space also had I condensed a few machines and bought this instead.

Actually Coop, it is the centripital force that causes the resistance. I built many atomic bombs you know!

i can see it as a belt squat subsitute but I don't think i would get it for anything else

and how do you progressive overload?

There is a flywheel system wich isn't expensive and also is vertical and horizontal. Basically all in one and affortable!

Damn! With that mustache you look like you could be Trevor Philips's long lost son from GTA 5!

Is it Movember already!?

Sweet stache Coop

So it's an upright rower?

No, I can't get into the mustache. I feel like I've been transported to TV show from 1981.

Why does your new camera setup look like you're filming in front of a green screen?

Check out the Strexbox.. it's half the price

I wonder how this affects joint health vs traditional weights. I’m 48 and the body is starting to break down.

supposedly the only thing Traoré uses in his training

You can attatch a propeller to it, move faster, and you've got yourself a homemade airplane. NO more Flight tickets!!!

That’s a lot of money 💴 more than I thought that it would be

But Coop that sweet stash though

Sold my VersaPulley MV2 and acquired the Sorinex Rack Attached** Exxentric kPulley2™ Flywheel. (** for Power Racks with 1" holes.) Sorinex Rack Attached Exxentric kPulley2™video - kzfaq.info/get/bejne/rMqnnNF41LutgGw.html Looks like I'll be selling my Sorinex/Exxentric kPulley2™ unit... and getting in line for the new Exxentric kPulleyGo!

How much is it?

Can you load it progressively?

I'd go selling these door to door if I could get them to give me 50% off. I would have pulled the trigger long ago if I could get the best model for 2k.... unfortunately 4k (for the set up I want) is just too much money to justify it....

Crazy expensive

Mustache or beard, one is necessary to maximize gains.

Space training.

meant to say mustache

I disagree on the endless amount of inertia idea. It's limited by how fast you can pull it. I highly doubt a barbell cannot create more resistance than a flywheel

You can build this yourself

$1800 too expensive

Flywheel training is the only true alternative to free weights.

lose the stash!

I love unnecessary things

Cool concept but I can’t take it seriously at that price.

That is just silly to be.

Ill buy 2 rogue racks for the price of this shit. Sheep are for shearing

This is way too expensive and unrealistic for anyone to buy. You’re better off buying a fully equipped cable machine than spending 2500 on this. This thing should be at most 600 dollars.

Yes it's not necessary. It looks like a gimmicky POS. I have to yank super hard to get it to do anything and when it reaches the end of it's ROM it yanks you down violently. See the squat and deadlift movements shown which when done properly have defined starting and ending points in the movement. It's a very expensive thing that looks like it's more likely to harm than help. Stick to barbells folks. Wait. I do see a benefit. It teaches bad form.

Hard af for him to get to the point. Listening to 10 min of bs to get 30 seconds of actual useful info. 😒😒

honestly it looks awkward to use, not one move looked stable at all. and i get that stability is a product of the core working, and all that crap, but it doesnt look even fun to workout with. and i get the "unlimited" ammount of resistance is more then a barbell but i dont know many people squatting over 800 pounds anyway. im gonna have to say no to this, its awkward, weird, and just all around not something i see many people wanting to use. also its a no from me on the mustache. way to thin and short. mustaches need to be commanding not just a strip of hairs on the upper lip you missed while shaving
