Using a Flywheel for Serious GAINS - Exxentric kBox4 Review

[@GarageGymLab]

Have you ever used a flywheel before? If so, share your thoughts!

[@johnnygunzfilmbuff7821]

No I have never used this. Not desperate to buy this nothing against it dosent interest me and one equipment I can survive without.

[@steverapos3904]

@@johnnygunzfilmbuff7821 I bought a knock off version of this - it really does provide a unique experience. I would rather use a barbell and weights but I didn't have the space so this was an alternative for squats and deadlifts. It is a good idea and provides a different stimulation to the muscles but unfortunately it is really expensive - if prices were more reasonable I think flywheels could get quite popular.

[@michaelbutler3250]

One of the best reviews I have ever seen. I am 62, used to own all the stuff. As you age, your get more focused. I use this and have sold 99% of my former gym, and it was nice! I use this for squats, rows, dead’s, curls. I do the rest with pull ups on a stud bar and dips on my bar stools, I sprint and shadowbox. This thing is fantastic. Wish I would have known 40 years ago

[@MudPig6110]

I picked one of these ups about 4 months ago, its amazing. I bought it to supplement the standard squat rack/bench setup I have, but it actually could almost replace a whole gym setup. I don’t even do normal bar squats anymore due to the kbox’s belt squat capability. That’s just one of 20 plus movements you can do on it. If you are thinking of getting a belt squat machine or have limited space this piece of equipment is a must have.

[@GarageGymLab]

Thanks for sharing, Aaron!

[@Crazytaru1]

I just got the kpulley go, 2 of them even though its not necessary. They attach to my rack and I can see what you mean about it replacing a whole gym. I really want a kbox after using the kpulley. The stimulation is similar to squatting on squatmax with bands but dare I say it, its even better on the fly wheel

[@K4R3N]

What does it feel like? How is it different from barbell or single leg dumbbell squats/lunges? More/less challenging, safer etc?

[@MudPig6110]

@@K4R3N it’s a lot more challenging. It contracts your muscles both eccentrically and concentrically so it is like doing double the work. Great addition. This and a bench with some adjustable dumbbells is all you need.

[@1999TransAmWS6]

I've had my Kbox active for almost a year now. I still use it all the time and really like it. The burn I get from it is unlike anything I get from standard weights. I primarily use it for squats, bar and rope curls, one arm rows, bent over bar row, deadlifts, lying tricep extensions (I move my bench over to it so the pulley is behind my head. I have to put weights on the Kbox so it doesn't lift off the ground). I still do squats and everything else with barbells too but it's nice to change it up to have some variety in my training. I have the advanced flywheel knob with 4-Large plates, 1 medium, and 1 small. I recently built a 1" platorm to raise the Kbox so I can purchase the XL plate. The reason it won't fit is because the Kbox pro is slightly taller and allows it to clear. Expensive but worth the money in my opinion.

[@GarageGymLab]

Thanks so much for sharing, Jason! Great idea on raising the platform.

[@1999TransAmWS6]

@@GarageGymLab Thanks for all your videos. I purchased the proloc collars after seeing your video with them. I've been looking for collars to fit my BS Strength hip thruster bar. Spring loaded and standard clamp wouldn't work since the bar is slightly undersized. The proloc worked perfectly.

Do u think the kbox can replace my rhino belt squat and will it still be worth to get k box flywheel if I already have functional trainer, stand alone selectorized lat pull down, rack, rhino belt squat, isolator, echo rogue bike etc....???.

[@cetatlanta]

I have the K box and the K pulley. I really like both of them. The finish on the pulley matches my gray RM6 very well and works great attached to a post. I now do the majority of my squat work on the k box and I don't think I'm going back to a barbell anytime soon, if at all. I've noticed a huge increase in power, as evidenced by my max watts numbers on the air bike. I like the box better than the pulley, but if you have the budget for both it is a great combo to have. My favorite moves on the pulley are lateral raises and overhead tricep press with a rope.

Thanks for watching, Evan! Flywheel training is really fun.

[@generalpunisher]

@@GarageGymLab Did you find there was a long adjustment period when you first got into it? As you mention, the stimulus is pretty different from conventional gravity-based training. Did you have to recalibrate how you think about and perceive stimulus/load/stress on the body?

[@GarageGymLab]

@@generalpunisher there was a small adjustment curve, but nothing major. After a few sessions, I had it pretty well figured out

[@neilpollack3514]

I have a Kbox 4 Pro that I use for squats and deadlifts in my apartment. The main advantages over free weights is that it is so space efficient and quiet. I prefer weighted chins and dips for upper body. I do some pushups and inverted rows on the TRX because it’s just more convenient. I also use some dumbbells for shoulders. Again, that’s more convenient than using the flywheel for it.

[@GarageGymLab]

Thanks for sharing, Neil!

[@qwie100]

Would you be able to comment on how the plates sizes compare to lb/kg weights at a normal squat/deadlift speeds? I'm thinking of picking up the Active, and I'm not sure if a single L flywheel is enough.

@@qwie100 A 700 lb deadlifter named Jordan Fieganbaum of Barbell Medicine tried the kbox with just a medium wheel and said it was “legit”, but he did pull fast. My working sets are normally only around 300 lb, but I like to pull slowly and work on technique, so I have 2 XLs. I’m thinking of adding a couple more XLs to go supper slow. A small change in speed makes a big change in the load.

[@aidenbromaghin7303]

I’ve been looking into purchasing one as a substitute for a power rack/barbell setup as it takes up less space and is more compact. How do you feel your strength and hypertrophy gains from the flywheel compare to using traditional free weights?

[@steverapos3904]

I bought a fake version from Alibaba. Although I had some quality control issues (which were a big hassle to correct) and it took forever to ship, in the end I think it works about the same for much less money. It works ok for squats and deadlifts, but I actually like it better for upper body workouts as it really allows you to get a burn. For me, I am not used to belt squats and it is rather quad dominant, better with a squat harness. For deadlifts, it works but it is a bit jerky at the top - I still prefer barbell though. Overall, it is an alternative but I wish the price for the real version was more reasonable. I did notice some ads on Instagram recently for some new competitors that have more reasonable prices so I would also check those out.

@@steverapos3904 Obviously the Alibaba knock-off version is going to be nowhere near the quality of a high quality exxentric flywheel device..

How many plates/how much inertia do you typically use for a challenging squat or deadlift. Lets say im starting out at around 150kg squat and want to progress to a 250kg what kind of range of plates would I need to get that equivalent progression if that makes sense?.

[@Atif_Ph.D._Kate_Bush_Fan_Club]

Great video…By Casey Affleck. Seriously though very informative and I enjoyed it. Way too expensive 💰though. What are the makers thinking 🤔? You could buy a squat rack and barbell with weights and do every possible exercise with weights and equipment that would last your entire life. As opposed to this wheel mechanism which could easily get damaged and need repairing.

[@meisdetermined]

Man I have watched this video 3 times and for most of the movements I can closely replicate or emulate the eccentric overload on my other equipment. (Such as being able to lean back with the preacher pad and then slowly lower the weight). The one movement that seems hard to replicate is the sideways lunge/squat where one foot is on the platform and the other is on the ground. That seems very helpful with athletic movement. But what other ways are there to put stress on the body in a similar manner?? I’m just wondering if this movement is only able to be overloaded with this machine only.

[@Leonidas-eu9bb]

I have a more budget friendly flywheel product. I think the kBox from exxentric is the 'Ferrari' under the flywheels trainers.
