The “Kettle Bell” or Russian Kettle is a traditional training instrument developed in Russia and made famous by Pavel Tsatsouline and Valery Fedorenko. Basically it's a big, iron ball with a handle that you swing around, lift and juggle.

Essentially, the centered/raised position of the handle allows the main pay-load to swing, which means that you have to use your grip strength much more to control it, and it becomes harder to use natural mechanical advantage to lift the weight. This Instructable involves welding, bending and shaping metal at high temperatures and working with concrete.

Materials: -1 bag quite concrete mix (the “just add water” kind) -1 dollar store inflatable rubber ball (smaller than a basket ball, ideally) -2.5 ft. #8 (1inch diameter) Rebar or steel pipe (with rebar you get extra weight, which means less concrete, which means it's more compact and easier to use. Make sure you cut the ends of the top and side pieces at an angle so that they fit together flush.

If you chose to go with the forge/torch option, basically just make the handle shape in the above proportions by bending a single long section of rebar. If you used steel pipe, you can probably find corner fittings that will do the job and you can just solder them.

No matter what size you decide to make the handle, and of what material, be sure that the side pieces or 'arms' to extend a few extra inches so that they can have some decent depth when you set them in concrete. This is to reinforce the rubber because it will warp significantly when you deflate it and pour in the concrete.

You can also use a slurry of plaster of Paris, or plaster-impregnated gauze strips to coat the outside -- these will be more expensive and time-consuming, but will product much more aesthetically pleasing results. When it's pretty well covered, cut the holes out with a utility knife and connect them with a slit.

Once you have the holes set up and the slit in the middle to pour the concrete in you can fill it with water to figure out exactly how much concrete you'll need to mix, but be careful: the rubber is pretty fragile and even with the tape, it will rip easily. You can also get a slightly less exact measurement by calculating the volume of the ball.

Put the mold in your first bucket and pad it with some newspaper to keep it centered. I just took two long pieces of string and tied them to some ceiling beams in my studio and tied them to the corners of the handle until it hung parallel to the ground with the arms low enough down to sit in the mold in the right place.

Make sure the arms stick far enough down into the mold and that they are not so high up that you have a giant handle. I typically just mix by hand in a big bucket since it's only a small amount.

It doesn't have to be perfect, but the more water you have the weaker it will be when it dries and the harder it will be to work with. You can cut the top off of a wide-mouthed 2 liter bottle and use it as a funnel if you don't want to be messy, or you can just pour it in a scoop it out with your hands.

When the concrete has dried or at least cured to a reasonable strength, you can cut the mold away. The valve pokes out on the inside of the ball and will get stuck in your concrete.

1 bag of premixed concrete 1 cheap rubber ball 26 inches of PVC, either 3/4” or 1” in diameter A small bit of sand Duct tape Water Use a hacksaw to cut the PVC into 26” length and use duct tape to cover the opening of the pipe.

Fill it with the sand and then seal the opening of the PVC with more tape. Make sure you use an oven mitt or other heat-resistant gloves so that you don’t get burned.

Once it has cooled, if you don’t like the shape you can always reheat it. Then, create two circles at either end of the slit, as this is where your handle will be.

Use the garden spade to fill the ball and put your handle inside. Amy and Add Moreland are the creators and Headmaster Trainers for the Amid Strong programs.

Its wider handle makes it easier to grip with two hands (for the classic swing move), and its smoother finish is less likely to injure your skin over time. Dragon Door was the first company to popularize kettle bells in America, which is why the most other brands simply copy that shape down to the millimeter.

If the goal is to learn kettle bell basics and use two-handed techniques, all of these bells are quite suitable, and being budget conscious (finding sales/free shipping) isn’t a bad route. We (Keira and I) have trained more than 800 clients in kettle bell techniques since 2008, and we’ve taught multiple instructor certifications in the US and abroad.

(Most recently, as the coronavirus pandemic forced people to work out at home, significant stock shortages have become the norm.) Their unique shape and functionality give them many of the strength-building benefits of dumbbells while also providing users with the opportunity to do kettle bell -specific drills that involve a lot of movement, like the swing.

The closed-loop handle of a kettle bell offers users a secure grip for movements with both hands. Dumbbells are better suited to doing squats, curls, bench press, cleans, and other exercises that have less kinetic motion.

That means you can fulfill all your workout needs with one simple tool that stows easily in a closet. One important caveat to this endorsement of kettle bell training is that proper technique makes all the difference between effective and beneficial use and potential injury.

You can also consult credible online tutorials, and many trainers will set up a Skype arrangement where you can send videos to them for feedback and coaching. My wife, master ROC trainer Keira Newton, has an awesome YouTube page with all kinds of tutorials/workouts for kettle bells.

In terms of credible resources on kettle bell techniques and workout ideas, here are a few great sources available digitally and/or in print: Dragon Door has the most resources in terms of kettle bell books and DVDs (at least in the “hard style” approach that I use) available.

Finally, Steve Cotter is a master practitioner/teacher of competition kettle bell lifting techniques. While many people recommend women starting with an 8-kilogram bell (about 16 pounds), I think that the two-handed lifts like squats and swings aren’t very well-served by that low weight.

If you want to start modestly, my suggestion would be to get the 13-pound version of our budget pick and then order a larger, higher quality bell once you feel comfortable. With these three, all kinds of single and double kettle bell work is easily achievable and scalable.

Both of these linked pieces reiterate my earlier point about seeking credible instruction before beginning an at-home regimen. Then there is the question about which kind of kettle bell you should buy: cast iron, competition, or adjustable.

Also, a major frustration with adjustable kettle bells is that they don’t offer a wide enough weight range to make them ideal for many. As it turns out, there’s not a huge amount of difference between these things because most of them borrow their design from the Dragon Door ROC.

Dragon Door was the first US company to run kettle bell instructor certifications (taught by famed instructor Pavel Tsatsouline) and have mass distribution in the US (Dragon Door started selling these bells in 2001). Dragon Door bells achieved great acclaim, but their high price point (roughly $120 each after shipping and handling, the highest in our test) invited lots of competition from other companies.

CAP is another popular fitness company that makes a good bell at a lower price point. For example, this Yes4All bell is one of the most popular models on Amazon, but its large, flat face is hard on the wrists in one-handed positions.

Although much more rare, some companies compete by distinguishing their offerings from Dragon Door’s with different designs. Perform Better at one point implemented a screw-on rubber skid plate on the bottom of their bells, but later on scrapped it due to negative customer feedback.

From left: Matrix Elite, CAP Cast Iron Competition, Rogue, Perform Better First Place, Dragon Door ROC. Photo: Anton BrkicOur testing group, which consisted of myself and five members of the high school varsity baseball team I coach, worked with all five bells at the beginner/intermediate level and did only two-handed moves (dead lifts, squats, presses, high pulls, and swings).

In fact, I wouldn’t use the CAP or Rogue bells for high-rep snatching because they have coarse handles and some tackiness from the painted finish. If you order through the company’s website and have a problem, Kettle bells USA will “make it right, period!” by sending a replacement and taking care of return shipping fees.

Photo: Mark Blythe Matrix Elite kettle bell has a slightly different handle dimension and more distance from the ball part of the bell to the handle to create a larger opening for more comfortable two-handed positions. The Matrix bell clearly outclassed the competition for two-handed work, as the smooth, e-coated handle with a wider grip was consistently easy on the hands, even when doing high repetition sets of 20-plus kettle bell swings.

Even when the user advances to the one-handed moves, both two-handed swings and goblet squats should remain essential parts of a kettle bell program. Any flaws in a kettle bell will be exposed when you use just one hand, but the attention to detail in forging a smooth, seamless handle was clearly on display with this bell.

Besides the handle shape, the Matrix Elite (right) looks almost identical to the Dragon Door ROC, which costs anywhere from $30 to $50 more. Photo: Mark BixbyAnother thing that sets the Matrix Elite apart from other kettle bells (including Kettle bells USA's own “classic” line) is the fact that it’s designed to have the same “rack” position (where the round part rests on your forearm) regardless of weight and size.

Most companies use standard molds repeatedly, and inevitably, residue from previous castings creates uneven surface textures like edges or gaps. Finally, Kettle bells USA showed awesome customer service throughout my process of testing.

If you're used to standard Dragon Door ROC kettle bells (or any of its many clones), the Matrix Elite's rack position might feel strange at first, since the ball part sits higher up on the forearm by comparison. If you see the bell offered at full price (with no discounted shipping), wait seven to 10 days, and you should find it available more cheaply.

If the Matrix Elite is unavailable, or if you just want a standard-shaped bell without the wider handle, the Perform Better First Place Kettle bell feels the same in use as the high-end Dragon Door, but costs about 25 percent less. In fact, its dimensions are identical except for the extra half inch of flat base diameter on the bottom of the Perform Better bell.

While Perform Better wouldn’t divulge what process it uses, I noticed that it’s somewhere between a matte powder coat and a glossy e-coat. Reading user reviews (see here and here) that slam performs Better for having noticeable seams on the underside of the handle or other defects isn’t helpful considering the construction specs on their bells currently.

The bell I received from them was really well-made, and it showed no signs of being defective in build or user experience. I contacted Perform Better about this discrepancy, and company reps explained that among other small changes, they’d since switched to a gravity casting process, which creates a more uniform surface, as you recall.

It’s also worth noting that Perform Better frequently has sales on its kettle bells, and while it’s usually cheaper to buy Perform Better bells directly from the company, it's worth checking Amazon and Strongest before buying to find the best deal. If budget is your bottom line, then we’d recommend the CAP Cast Iron Competition Bell.

But unless you really need to save a few bucks, it’s worth investing in our top pick, since these things last forever. In fact, none of the five baseball player panelists said they would pay extra for any of the other bells for the basic routines they were testing with.

The powder-coated CAP (left) and Rogue (center) bells are rougher than the e-coated Dragon Door (right). Photo: Mark Blythe CAP bell has a powder-coated matte finish and a slightly gritty (though it’s evenly dispersed grit) handle to provide a good grip (though a bit on the coarser end of those we tested) and a flat bottom so it doesn’t rock when used for push-ups or rowing moves.

If imitation is the sincerest form of flattery, then the Dragon Door ROC Kettle bell should feel pretty good about itself. Unfortunately for Dragon Door, other companies have been able to duplicate its design at a comparable level of quality for a lot cheaper.
