[@Davis.smith.weightlifting]

While I agree it might be hard to do traditional progressive overload, generally strength and conditioning is trending towards velocity based training for the specific reason that it takes out subjective input of auto regulation and allows athletes to truly auto regulate. I think for most people this would actually be better for training because it eliminates the ego and also notice misunderstanding of exertion and allows the athletes to put in the work they’re capable of on that day. Progressive overload is a great scientific principal but only works perfectly in a controlled environment with no external variables adding any of millions of external stressors in daily life that could impact training on a given day.

[@kimomendoza5074]

Good review, as always Coop! But I’d rather spend $2K+ on a functional trainer.

Yep, totally get it. Thanks for the kind words.

[@shifter8207]

I was thinking the same thing

[@neilpollack3514]

Yes, most people would rather get a functional trainer but, 1. This is a different workout. Some people want this. 2. This takes up less space. Some people just don’t have room for a functional trainer. 3. This makes less noise. That can be an issue especially if you live in an apartment of have a baby. 4. This is portable. You can’t pack your functional trainer in your trunk if you have to move a lot.

It is equally outstanding. I don't have one complaint other than putting it together is a job. The instructions and packaging of the parts are very well designed and organized. Also, I stripped and damaged the pull down cable the first day, admitting it was my stupid fault, and they quickly replaced it at no charge. I'm 6'5, 280lbs and fit in the cage just fine. Glenn B

[@thomasbrown7328]

Coop you should have shown it with a rotational woodchop kind of movement- the flywheel really shines with that transverse plane stuff. For my kbox I can do those movements too - just put a couple kettlebells on the box and stand aside and chop away. Their attachment called the rotational sling is handy too for those movements to focus more on trunk and legs. As a whole the flywheel stuff is a nice supplement/finisher. The harness flywheel squats are so brutal you end up talking yourself out of doing them like the way that little voice in your head can talk yourself out of using the fanbikes/airdyne/echo.

Prepare for a future where all we get is cheap hardware and overpriced features on a subscription basis to subsidize it. If we don't support quality we deserve that outcome.

[@graham1034]

As someone with very little space, this could actually work really well for me. Right now I only have room for a bench and a set of adjustable dumbbells. I could probably clear out a little space on a wall to mount this, though having the room to move with the straps might be an issue. This is pretty comparable to a cable/weight setup but has the advantage of being much quieter (no weight dropping) which is a major plus living in a wood framed apartment. Not being able to measure progress and the awkward feeling of the resistance (compared to a traditional cable/weight setup) would be annoying, but with no alternatives I could get over it. The price is a little harder to accept though. If it was $1000-1200 then maybe I could justify it.

[@johnhemphill80]

I love this channel and reviews. I wish you would do more reviews on cheaper home gym equipment. $2200 is much more than alot of people will pay.

More important than the product, Coop, you're looking in great shape! Kudos. Fleewheel training thankfully isn't my thing, because all of the products in this area are ridiculously expensive. These are a great addition to a commercial gym or someone that has a studio/training space to take PT/S+C clients.

[@seanfan84]

High quality material? Zinc plated Machined steel? I’d rather say it intellectual property worth. It is a very smart design.

[@BeGrizzlyStrong]

The machining costs are probably more eye-wateringly high than most people would believe. I wonder about how sturdy it is. Precision machines often sacrifice ruggedness.

[@seanfan84]

@@BeGrizzlyStrongstainless steel 316 is $4-6 per kg, mild steel $2-3 finished. Depends on where you are. Does not need to be strong. Never gets dumped. I thought about it for a day, i assume it pulls back with the same force you pull it out. the pull during release cycle is annoying. If you jerk it, i dont know if it’s gonna jerk you you toward the upright. Then you could actually get hit. So better Easy steady does it.

[@billklatsch5058]

@@BeGrizzlyStrong Its not the machine that makes the part expensive its the guy who operates it. Also literally every machine on the market can produce results in the IT7 tolerarances or better on repeat if the operator has at last some clue what he is doing.

underrated comment

[@hinmanj88]

I've been using the kmeter app more recently, and though I have a bunch of issues with it (like accidentally losing my sets before I save them when I'm trying to delete a pre-rep), you can set your "Inertia" (i.e. how much flywheel mass you have on the unit) and then when it auto-tracks your reps it gives you exact power/force readings for concentric and eccentric portions of the lift (per rep!), as well as range of motion, average/peak speeds, etc. So when you say one of your complaints is that it's hard to track your progressive overload progress, I'd almost say it's even more fine-grained than with barbell training because you know exactly how much force you're producing *per rep* whereas when you're doing a barbell squat you just have a general feeling of how your reps went. Recently I've been loading 2 L flywheels on the kbox and doing squats and I've noticed that I get progressively more force-producing with each workset until about the 4th or 5th and then I start to deteriorate, but from workout to workout I have good guidance for how my force production in general is changing (i.e., increasing slowly). Tangentially, I own both the kbox4 and kpulley2 (thanks to your original review of the kbox) and though I use the kpulley2 more often (for rehab'y type movements) - as someone who likes barbell training I agree the kbox is more versatile. Just look at what Stefan Ostling has been doing with it on instagram for example (posted yesterday): instagram.com/p/CKMqyyksjKA/

[@GarageGymReviews]

Wow, this is very helpful information. Thanks for taking the time to share. I need to play with the kMeter more. I actually follow Stefan now. So many great ideas and another reason why I think this type of training is underutilized.

300 USD gets you a set of dumbbells up to 20lbs, a barbell, standard squat rack, standard cable pulley machine.. the kbox provides something unique to those things, but a minimum of $2000 seems very steep even then

[@neilpollack3514]

It’s a shame that Coop didn’t explain the real use case for this device. If you have the space for a rack, barbell, functional trainer, etc, and noise isn’t an issue but money is, then this isn’t for you. This and the kbox are either for somebody who doesn’t have the space for traditional equipment or needs to avoid the noise and can afford an expensive alternative. Or, it’s for somebody who has everything and wants to change up their training once in a while. I spent around $4k on the Kbox pro, but I live in an apartment where space and noise are issues. I could have rented another apartment to have space for a rack and barbell, but that’s $4k/month here. So, this was actually much cheaper.

Oh okay so how much force you use for the concentric, determines how much force the flywheel produces for just the eccentric. That sounds difficult to keep things consistent. People sometimes like to do some reps more explosive than others, but with this flywheel, that would then give them a really hardcore eccentric in the middle of their set to deal with. Some of the demonstrated exercises looked weird as far as the pace and stuff goes. Definitely interesting.
