I got one when I started remote work and it works pretty decently in my home office. Compact, looks clean, quick adjustments. Only use it for swings, TGU and press.
@@GingersKing Agreed but at least they can go up to 70 pounds, I don't see many people that've been working out for more than a year finding much use with a 40 pound limit bell, outside of super setting presses or something.
I have the 840s and love them. I would have liked for it to be heavier but I found that they really shine doing double kettlebell work like in the shock and awe protocol. I swing 90lbs but two 40lb 840s have opened up a whole new world for me in kettlebell work
I have 2 Titan Fitness adjustable competition-style bells (which range from 26-70ish lbs each) that I love. Changing weight is not as efficient as the Bowflex but I was willing to trade efficiency for the weight range and handle/shape.
Curious what weights did you get after growing out of the bowflex? I just got mine today, so it’ll be all I need for a while. I’ve seen a lot of recommendations for 50lb, then 70lb, which sounds like the most I’d ever need - but I’ll probably get a second bowflex first.
@@AdamsBrew78 I started simple and sinister which called for 24kg which was a relatively easy jump from the bowflex. Then went up to 32kg and have a 40kg which I'm not really strong enough to properly use but maybe one day.
I picked up the Titan and it's a great kettlebell. Changing the weight is much slower than the bowflex (I had the bowflex and returned it), but it's perfect for my needs. I returned the bowflex because my hand kept hitting the dial and the design is shitty for the 45 degree kettlebell grip.
@@deadapostle good to know! Yeah it seemed very slow to adjust the weight but it also seems very sturdy and seems like it would feel most like a normal kettlebell.
Coop , my dude , pal,bud , mate , friend , can you please do drop tests on the all them adjustable dumbbells, from different heights , pretty sure the general public will benefit a lot from that info.
I had that kettlebell. It felt like good quality but rattled a bit when doing exercises which was annoying. Sold it because I just don’t use kettlebells very often.
Coop! Always with the selectable stuff! A plate loaded adjustable kettlebell, like the Fitness Gear model Dick's sells, is a much better buy. You use the same "standard" plates you use on your spinlock handles. Plate loaded anything is almost always the most bang for your buck.
@@redwhiteandblueblood Thanks! Once I grow out of my 5-90 PowerBlocks I was thinking of getting a set of Ironmasters, knowing they have a kettlebell handle seals the deal, down the road
@@joecowan3719 highly recommend if you outgrow your powerblocks You'll still get some decent resale on the Powerblocks too I'd imagine I have 2 sets of Ironmasters as I find them superior for heavy compounds over lighter accessory movements so I do all my pressing, rows, shrugs, RDLs etc with them and always leave 1 pair loaded with at least 55lbs so I'm not changing plates all the time. Ive got a 75lb set and a 45lb set and 2 kettlebells, but I also have the 120lb add on kit to expand the 75 pounders. For the really big boys, there's a 165lb add on too, but that voids the lifetime warranty as apparently they weren't designed originally to go that big, so I'll probably add the heavy handle kit in due course and that will max out the 120lb set at 135lbs and should retain its lifetime warranty still. 135lbs is just over 60kgs so plenty of weight there.
@@redwhiteandblueblood Thanks! I think we will do something similar, keep the Power Blocks for any workers from 5-90 and drop sets and use the Ironmasters for the heavy work. If I am lucky enough to get strong enough to need up to 165lb dbs then I can get one of the DB spotter systems. By the time I need to expand to the Ironmaster, the surge in demand will have ended and I may be lucky enough to snag a set on the used market as well. Thanks for your thoughts on these and happy lifting 💪!
Nice review as always. Agree that they are weight limited and the casing is potentially fragile. I did not have room for a set so I made adjustable kettlebells using 3/4 in pipe and fittings. They work well and I can load them up very heavy with standard plates and they won't break unless I throw them off a parking garage or someting.🤣
This review is very myopic and he overlooks several things. For starters, the plastic encasing that the Bowflex has is actually quite nice because the encasing keeps the inner plates from your body from usage which some of the other adjustables lack. This is the best adjustable kettle on the market due to best design.
I would have thought he'd like the PowerBlock Adjustable Kettlebell better. Even though it only goes to 35 pounds it looks a lot more solid and compact and has a proper handle on it. Will be interesting to see that review.
They have this up on the rewards network at my job and I'm considering it. Originally I bought a kettle grip for my Dumbbells, but I have the clunky adjustable dumbbells where you have to screw plates on and off and they're kinda bulky, and too wide to do swings without breaking some knees lol. I might have to cash in my rewards on one of these!
Great video bro keep up the good work. Your channel has helped me out a lot with finding products for a good home gym awesome review ? And have you done a review on the powerblock adjustable kettlebell but great video awesome review God Bless
Seems to bulky I would like to see your review of the two other power block kettlebells. My 1st set of adjustable dumbbells was the Selectec but I found them to be too long and to bulky though the weight adjustment was the quickest that I seen. I would have to pass on this one.
I'm a 51 year old, 250 lb guy...drywaller. so I have strength and I'm not very flabby. I run 10k's and even some longer trail runs. But I want to add strength training. I see this on sale at Canadian Tire now. Good option?
Nice video. What made you buy the bofwlex instead of the power blocks kettle bell handle? I have the same power block dumbells🙂 Iam thinking both the bow flex and power block handle are unconformable to do certain kettle bell movements, however good for swings and other basic movements...I also like the rep fitness adjustable kettle bell a lot.. Please help me decide between bowflex, power block handle to use it with existing power blocks dumbbells or rep fitness adjustable kettle bell?? Thank you. By the way I already own power block dumbelss like yours...I also have a 10lbs, 25lbs and 35lbs regular kettlebells
I'd like a comparison between the 3 types of adjustable kettle bells you have shown. I own the old Powerblock kettlebell handle that is compatible with the regular Powerblock
After getting the plate loadable kettlebell from titan I have no further interest in kettlebells as it does everything I need. But I pretty much just use them for swings.
It’s expensive, at least in Europe, for what you get. You could buy 4 Rogue kettlebells for the same price (12, 16, 20 and 24kg) which is a no brainer for me.
How durable can a System be where the weight ist dynamically held by a single pin in axial direction? I think thats a major difference comparing it to the dumbell
Thanks Coop for all your videos because of then I purchase a powerblock pro exp all stages. I was wondering can you review their kettlebell , the handle and the pin ones. Thanks getting into weight lifting thanks again
Hi! How does the kettlebell work for transporting? I haven't seen you pickup and move the kettlbell all together? Can you move the kettlebell all as one piece? How do you carry it to a different spot
I just purchased two. So far it’s good. Like you said it’s not like cast iron, but for what I need and in my basement it works fine. Also, 40 pounds is not that lite depending on the exercise.
Ya know, I don’t particularly care about the Bowflex Kbell, but I do enjoy watching your videos for the info. Maybe its time for you to take on a fitness goal (other than working out for longevity!) so you can have several topics going at once. Plus, you’ll see all of your equipment through a different lens once you specialize in a strength sport. Maybe you just want to use that incredible base you have to put on 20lbs of muscle, perhaps a strongman, powerlifting or kettlebell comp? What do you think?
How does the weight change by the turn of the knob if all the individual weight plates are in the hull? If all the plates are in the hull don't you lift the maximum weight?
This one is a hard pass for me. For the weight, this one is a case where adjustable dumbbells are a better option if you need something adjustable. For kettlebell training, stick with the original.
A few other companies sell the same comp style adjustable bells as kettlebell kings such as SoCal kettlebellz or bells of steel. Titan has some which are similar but not exactly the same. Another thing about the adjustable comp bells is that they feel like a real kettlebell vs kind of like a kettlebell and they’re all steel (with iron plates) and the only plastic that’s associated with them is a little bit in the packaging. Plastic is great stuff - but not for kettlebells.
@@stefhirsch6922 Since I left my original comment, I bought an adjustable competition-style bell from Kettlebell Kings and I LOVE IT! Have to agree with everything you said about how they feel and handle. I'll look into the other brands you mentioned since it's always good to have options. Now I only wish they had an option to go up to 48kg. The jump from 32kg to 48kg is a bit too steep for me for pressing.
@@fallingleaveskungfu a few other companies sell the exact same thing as the kettlebell kings competition style adjustable kettlebell. At least in North America bells of steel and “SoCal kettlebellz” have the exact same thing as the KK one. I’ve got 3 adjustable comp style adjustable kettlebells from titan which are basically the same but the fit/finish isn’t as nice - they also only come with 1 wrench which is the 8mm hex wrench. To make a kettlebell a little heavier you can either tie a weight plate onto the handle or duct tape a plate (or plates) onto the bottom (making an x where it wraps around most of the round part) both work. If doing swings, presses, tgu, windmills, loaded carries… either work. If you want to do cleans or snatches duct tape will get the job done. I used gorilla duct tape but haven’t tried other types. The plate(s) might shift a little but were surprisingly solid. I only used 1.25, 2.5, 3 and 5lb plates with the duct tape. I’d proceed with caution if I wanted to try to add 20lbs/9kg. Having the extra weight come loose and falling on your head is a concern.

@@lilbeanermexican Lucky!
I really love my Bowflex kettlebell, which I got at Sam's Club for $89. Being 71 years old, I'll never need anything over 40 pounds.
So cool to hear someone still working out at that age!
Your an inspiration
You need to do a full comparison like you did with all the adjustable dumbbells. Would love to see that.
Make this video pls
Would love this video of a comparison! Yes yes yes!
I looked all over for this how come it doesn't already exist?
I got one when I started remote work and it works pretty decently in my home office. Compact, looks clean, quick adjustments. Only use it for swings, TGU and press.
Perfect for the home office, lunch break training session 💪.
The kettlebell kings adjustable competition bell is still undefeated
True but they are always on back order. I been waiting for over four months.
Those look nice but man, that's really cumbersome to adjust the weight. 🤔
@@GingersKing its not to bad.
@@GingersKing Agreed but at least they can go up to 70 pounds, I don't see many people that've been working out for more than a year finding much use with a 40 pound limit bell, outside of super setting presses or something.
@@GingersKing The price i pay for the damn things staying in place while you swing them around
While I haven't used it myself, the reviews for the Kettlebell Kings adjustable kettlebell that I have seen have been positive.
Titan sells a similar one that is more easily adjustable, and is $65 cheaper.
Coop: as the name suggests the 840
Me: Weights 840lbs??
Coop: goes from 8-40lbs..
This comment made me 😁
The creators of this kettlebell
" Sir we have some neutron star matter , what should we do with it ?
I know exactly what to do with it "
Thanks for the review. It makes a difference hearing from someone who actually knows how a kettlebell works and how it adds to workouts!
I got one for $80 at target because they had the price mislabeled on the shelf and had to honor it. Big score for me!
Lucky 🍀
I have the 840s and love them. I would have liked for it to be heavier but I found that they really shine doing double kettlebell work like in the shock and awe protocol. I swing 90lbs but two 40lb 840s have opened up a whole new world for me in kettlebell work

All right. It's time to do an adjustable kettlebell multi-company review. To answer the question what's the best adjustable kettlebell to buy.

That's when you know you like a product when your willing to gift it as well.
Found one of these today at my Walmart for 50 bucks. Honestly for that price, it can’t be beaten.

Turn the dial and it locks in the weight.
