I am not very verbose,so all I can say it is a great product. Back home in Berlin I used to have a Russian friend with kettlebells (24 kg and 32kg), so I can compare. Your product is for me as good to use as the real kettlebells, and has the obvious advantages of being much easier to transport and adjust in weight. MS Germany
Rudy really likes the Kettlestack handles. He's hardly using those p*****s (adjustable dumbbells) as much now. The Kettlestacks are more explosive. I told him, "watch out!" they are killers for power and speed. Hell, now he wished that he bought the Kettlestack handles in the first place and used all that money he spent on the p*******s (adj. dumbbells) ($900) for purchasing a COUPLE of hundred pounds of standard plates and two inexpensive spring or spin collar dumbbell handles to do his dumbbell exercises with, at least he could actually drop those spring/spin collar dumbbells and not have to worry about them bending or breaking. Live and learn through the wallet.
Speaking of bending, I was looking at your web-site last week and noticed some cheap imitation copy of the Kettlestack handle. what a piece of garbage. a good selling point for Kettlestack handles though. All good quality products out in the world are often IMITATED but NEVER duplicated. Good luck to those cheap bastards out there buying those crappy grip handles to save a dollar or two. Stick to the original that has been researched, tried, tested, patented and proven by the ever growing number of testimonials. I hope you keep showing that video for safety sake, it would be a shame to see someone getting hurt from buying and using those imitation grip handles.
It won't matter in the long run as these un-informed people are not serious about training. To lift safely especially overhead or heavy is it really worth it to buy and use sub-standard equipment? Penny wise and pound foolish. When they start lifting some heavier poundage's and getting hurt, some of those injuries that don't always heal correctly and can permanently damage a once healthy body. I hope people will think before they buy those cheap imitation kettle grip handles.
My training is going great, doing some outside double snatches like 2005 WPO SHW power lifter champion Donnie Thompson. I am purchasing your Steve Cotter DVD set. Hope it's as good as or better than Mike Mahler's. It will probably be equal, as everything you guys do from the service to the products has never disappointed me.
The main advantage I see from adjustable kettlebells is "price", in a sense of the word. I have four kettlestacks (www.kettlestacks.com) and they function as a complete set of kettlebells from 10lbs up to >100lbs. Some people will say there is an advantage to progression, and that the large jumps in traditional sizes are a disadvantage, but I don't see that as an issue, for the most part. Varying the resistance by varying the sets reps works just fine.
Price flexibility is the big deal to me. Depending on how I want to work that day, I can adjust the kettlestacks to what I want to do (it's easy, doesn't take much time at all). For example, any given workout I can use (2) 1-pood, and (1) 1.5-pood and (1) 2-pood, or any other combination of the above, or go higher or lower than the above in any combination. Buying the four stacks and all the standard plates set me back around $300, but I have a complete set of kettle bells, 1, 1.5, 2 and >2 KB's. I agree with an earlier post about not throwing adj KB's. That's a disadvantage if and only if you plan to do throwing movements. Also, I can use my std plates that I bought for my kb's for my std dumbells.
As for the type of adj kb's, I looked into many and settled on the kettle stacks as my choice. I called and talked personally to USA Ketlebells and kettlestacks and was just more comfortable with the durability of the stacks, but they were both helpful and very polite.
The only thing I can't comment on is the "feel". That's a bit esoteric to me anyway. I get a great workout with the adjustables, and thats what I want. The only real reason I want to someday purchase dragon doors is to support what I think is a fine institution. But for me, I couldn't afford the full set yet, and I'm sure Pavel would rather have me working out with adj kb's than waiting to buy his, especially since I suppory DD by buying his books and DVD's.
Good luck, you can't really go wrong so long as you start with something.

I've got the old style Kettlestack, which I enjoy immensely. I arbitrarily chose the middle hole for all my Kettlestack builds (35 to 55 pounds). Do you have guidelines for which hole to use (e.g., for less than 25 pounds use the hole closest to the handle)?
I tried a couple of brands of cast kettlebells today. I found that they caused intense pain in my wrist--they hit a spot much closer to my wrist than my Kettlestack. I'm wondering if they have a crappy design, or am I spoiled from my Kettlestack!
I would like to purchase another kettlestack for double KB movements--can I set up a new-style Kettlestack such that it has the same height as my old one?
Thanks!
Just got my first Kettlestack (adjustable kettlebell). I love it. Feels just like regular kettlebells. The cost is equal to the shipping cost of some kettlebells! SL, Brooklyn, New York
I have always enjoyed doing snatches and cleans and the kettlebell versions are quite explosive, closer to competitive movements than I have felt with pulling and pushing barbells and dumbbells. It (kettlestacks) is an amazing supplement to the practical old school barbell and dumbbell exercises that wrestlers, field athletes have always incorporated into their training. The thick handles are a bonus for gripping strength, no straps needed here.
Varying the weight is very fast and simple as you advertised and there is no worrying about anything breaking on a missed pull or push. I controlled dropped a 105 pound one arm repetitive kettlebell clean on a missed 4th set. No damage, no problem, Next set, all set to go. My friend spent a couple of hundred dollars for a set of quick change dumbbells and they are not made to be dropped at all. Let's just say he is lucky that his father is a welder.
No adjustable dumbbells on the market today with cheap plastic parts can match these tough kettlebell handles using solid steel plates.. Simple, tough and practical. Who could ask for more? Undersold is an UNDERSTATEMENT on your marketing. I have the Mike Mahler kettlebell DVD . The Kettlestack kettlebell handles and his DVD are a killer combination. DW British Columbia, Canada

These things are great. I have 3 here is my payment for 2 more!
It is really a genius idea that solves a lot of problems. I have more than one set as as luxury to allow me to move quicker between sets. When these arrive I'll have 2 as 35 lbs, 2 at 55 and 1 at 70. As I get stronger I'll go to 2 55s, 2 70s and 1 80 or 85. I priced out some fixed weight KBs and price-wise it made no sense. I have been working w/ your product for a few mos and I am very pleased.

I have had the kettlestacks (adjustable kettlebells) for a week and they work great. I am so happy I went with your product rather than a solid kettlebell. Being able to increase the weight in increments is very important when your doing challenging ballistic exercises. I quickly found out that 1 1/2 pood kettlebell would have been way to heavy. The 38 lbs. I've got set up is a great start for me in the ballistic moves, but I can set up more weight for the grinds in minutes. Thank you for such a good product. A.S. British Columbia
I ordered your kettlestack handles while deployed to Iraq last year and was very pleased with the ability to change the weight so quickly. Though they thought I was crazy at first, my fellow Marines were impressed as well and made me leave them behind when I returned to the states. The other guys and I were really impressed with the short time it took to buildup strength using the kettle bells. Especially when I, being the smallest guy on our team, could do a bottoms up press with 50lb bells. Now that I am back and tried using the regular gyms on base, I just don't get the same workout as with the kettlebells. A few friends and I are looking to buy a few more and start working out in the barracks and at home. Thanks for a great product.

More kettlebell stuff . . .
Hello everyone - - I've never used kettlebells before but would like to try them out. After reading over this website the Kettlestack seems like a good way to go since it is very versatile and expandable (and I have lots of weight plates). My question is - - what handle would be best for me to get ? More kettlebell stuff . . .
with a 70 pound base, does that mean i can load it with 70 pounds of plates, or 70 pounds including the weight of the handle ( 67.5 pounds of plates plus the handle)?
thank you
Hi folks,
Just wondering what the best option is to get a pair of kettlestacks in Canada. Shipping them from the states? Or is there an official supplier in Canada that would be better?
I'm trying to figure out which hole I in the handle bands I should be using? There are 3 - a little one (same size as the Allen wrench) then 2 big ones. Do I use the top big one or the bottom one?? Seems to make a lot of difference as to where the weight lands on my forearm.
Thanks,
PS. Awesome product.

Pretty decent prices and shipping is reasonable as well, just thought I'd share with your guys here. I plan on getting the 7.5 plates from here if I can't find them local.
I want to build up a 35 pound kettlestack
which slot should I use ?
