In the contest for fave free weight, kettle bells are quickly gaining on dumbbells and barbells for the top prize as more people catch on to their versatility—they let you train for power, muscular endurance, and strength all in one weight, says kettle bell specialist Lauren Kan ski, CPT. Part of what makes them such a complete package is the way that they're designed: “The kettle bell loads the weight on one side instead of it being evenly dispersed like a barbell or dumbbell,” says Kan ski.
And while all KB's have this one feature in common, there are other distinguishing factors to consider before buying one. Laura Miranda, DPT, CSS, points out that heavier weights are good for power movements like swings and snatches, while lighter loads are ideal for things like presses and Turkish get-ups.
Opting for an adjustable kettle bell lets you play with different levels of resistance with just one weight. You can also consider going for a soft kettle bell set instead, which will protect you and your floors in case of accidental drops.
Bottom line: The weight set you should buy really depends on your lifting history, says Kan ski. But for newbies, she considers 8–12 kilograms to be a good range for women working on overhead movements, and a little heavier for lower body movements, like swings and goblet squats is a good idea.

A 16-kilogram (35 lb) “competition kettle bell Arthur Saxon with a kettle bell, cover of The Text Book of Weight-Lifting (1910)The Russian girl (, plural girl) was a type of metal weight, primarily used to weigh crops in the 18th century. They began to be used for recreational and competition strength athletics in Russia and Europe in the late 19th century.
The birth of competitive kettle bell lifting or Gregory sport ( ) is dated to 1885, with the founding of the “Circle for Amateur Athletics” ( ). Russian girl are traditionally measured in weight by Food, corresponding to 16.38 kilograms (36.1 lb).
The English term kettle bell has been in use since the early 20th century. Similar weights used in Classical Greece were the halter, comparable to the modern kettle bell in terms of movements.
Variants of the kettle bell include bags filled with sand, water, or steel shot. By their nature, typical kettle bell exercises build strength and endurance, particularly in the lower back, legs, and shoulders, and increase grip strength.
The basic movements, such as the swing, snatch, and the clean and jerk, engage the entire body at once, and in a way that mimics real world activities such as shoveling or farm work. Unlike the exercises with dumbbells or barbells, kettle bell exercises involve large numbers of repetitions in the sport, and can also involve large reps in normal training.
Kettle bell exercises are in their nature holistic; therefore they work several muscles simultaneously and may be repeated continuously for several minutes or with short breaks. This combination makes the exercise partially aerobic and more similar to high-intensity interval training rather than to traditional weight lifting.
In a 2010 study, kettle bell enthusiasts performing a 20-minute snatch workout were measured to burn, on average, 13.6 calories/minute aerobically and 6.6 calories/minute anaerobically during the entire workout — “equivalent to running a 6-minute mile pace”. When training with high repetitions, kettle bell progression should start out slowly to build muscle endurance, support the joints and prevent injury.
Like movements performed with any exercise tool, they can be dangerous to those who have back or shoulder problems, or a weak core, when performed without proper education and progression. They can offer improved mobility, range of motion, agility, cardio vascular endurance, mental toughness and increased strength.
The following is a list of common exercises that are uniquely suited to the kettle bell for one reason or another. A kettle bell exercise that combines the lunge, bridge and side plank in a slow, controlled movement.
Keeping the arm holding the bell extended vertically, the athlete transitions from lying supine on the floor to standing, and back again. As with the other slow exercises (the windmill, get-up, and halo), this drill improves shoulder mobility and stabilization.
It starts lying on the ground with the kettle bell over the shoulder in a straight arm position, as in the top of a floor press, but with the other arm along the floor straight overhead. The trainee then gradually turns their body away from the kettle bell until they are lying partially on their front.
The kettle bell is held hanging in one arm and moved smoothly around the body, switching hands in front and behind. Also called a front leg pass, this is a backward lunge, circling the bell around the front leg, returning to the standing position, and repeating.
Like the slingshot, but the bell is swung forward until the arms are parallel to the ground. Starting with the bell in the rack, the bell is pushed away to the side slightly, the swung down to the other side in front of the body, and reversed back up into the rack.
A variation of the press where the other arm assists by pushing open palm against the ball. Stand on one leg and hold the kettle bell with the opposite arm.
By then lowering and raising the kettle bell you can work stabilization and power. A press utilizing a bent-leg windmill position to lift heavier weight than is otherwise possible.
One bell is rowed to the chest while maintaining the plank position, then returned to the ground and repeated with the other arm. Alternatively performed with a single kettle bell, one arm at a time.
This requires more control than an ordinary push up and results in a greater range of motion. Feet may be elevated to increase the difficulty, until the trainee is performing a handstand push-up on the kettle bells.
In any movement involving the rack or overhead position, the kettle bell can be held with the ball in an open palm (sometimes called the waiter hold) for a greater stabilization challenge, or for even more precise control and added grip challenge, the bottom-up hold, squeezing the kettle bell by the handle upside-down. Holding a single kettle bell in the rack position bottom-up with two hands (“by the horns”) makes for goblet exercise variants.
Conventional swing: The kettle bell is swung from just below the groin to somewhere between the upper abdomen and shoulders, with arms straight or slightly bent, the degree of flexion depends on the trajectory of the kettle bell. Hang clean: The kettle bell is held in the rack position (resting on the forearm in the crook of the elbow, with the elbow against the chest), lowered to below the knees, and then thrust back up in to the rack.
The kettle bell is held in one hand, lowered to behind the knees via hip hinge, swung to an overhead position and held stable, before repeating the movement. Jerk: As a push press, but with two dips, for more leg assistance (as in the barbell clean and jerk) Thruster: A rack squat with a press at the top using momentum from the squat.
Pistol squat: A single-leg squat with one leg held straight in front parallel to the ground, holding the bell in the goblet or rack position. An easier variant for those with less hip mobility is to perform the squat parallel to a step or ledge, so that the foot of the free leg can dip beneath the pushing leg at the bottom.
Carry: Walking with the kettle bell held in various positions, such as suitcase, rack, goblet, or overhead. Row: While bent over anywhere from 45 degrees to parallel with the ground, the kettle bell is held hanging from a straight arm, pulled up to the hips or laterally, and lowered again.
Keeping the bell arm vertical, the upper body is bent to one side and rotated until the other hand is touching the floor. The single kettle bell version is called the suitcase walk.
These build grip strength while challenging your core, hips, back and traps. The kettle bell is swung from just below the groin to somewhere between the upper abdomen and shoulders, with arms straight or slightly bent, the degree of flexion depends on the trajectory of the kettle bell.
The key to a goodkettlebell swing is effectively thrusting the hips, not bending too much at the knees, and sending the weight forwards, as opposed to squatting the weight up, or lifting with the arms. The one-arm swing presents a significant anti-twisting challenge, and can be used with an alternating catch switching between arms.
Within those variations there are plenty more variations, some are, but not limited to: pace, movement, speed, power, grip, the direction of thumb, elbow flexion, knee flexion. The kettle bell has more than 25 grips that can be employed, to provide variety, challenge different muscles, increase or decrease complexity, and work on proprioception.
Competitive lifter (Greek) performing jerk with 32 kg kettle bells (rack position). Contemporary kettle bell training is represented basically by five styles. Hard style has its roots in powerlifting and Gj-rykarate training, particularly hobo undo concepts.
With emphasis on the “hard” component and borrowing the concept of time, the Hard style focuses on strength and power and duality of relaxation and tension. Gregory, sometimes referred to as the fluid style in comparison to the Hard style, represents the training regimen for the competitive sport of kettle bell lifting, focusing on strength endurance.
Juggling is a training style where the practitioner releases and catches the kettle bell with all manner of spins and flips around the body. Kettle bell training is extremely broad and caters to many goals, some being, but not limited to: mobility, flexibility, cardiovascular endurance, strength, speed and power.
The sport can be compared to what the CrossFit Games is to CrossFit, however, the sport has been much longer in existence, and is only recently gaining more popularity worldwide, with women participating as well. One such example being Valerie Wazowski, who at age 52, was the first US female lifter in the veteran age category to achieve Master of Sport in 24 kg Kettle bell Long Cycle.

Though kettle bell lifting competitions are relatively new in the United States, they have historical significance in other parts of the world. Kettle bell training was “discovered” by U.S. athletes and particularly mixed martial arts fighters.
Kettle bell workouts are designed to increase strength, endurance, agility, and balance. However, since practically any KB exercise can also be executed with a dumbbell, it is reasonable to ask why you should use a kettle bell instead?
The kettle bell shape (remember the “cannonball with a handle” description) makes the weight displacement different from a dumbbell's. The off-center weight of a kettle bell makes it more unwieldy, requiring the use of more stabilizing muscles to control it.
By the nature of their design, nearly all kettle bell lifts are compound movements that work the body as a whole, rather than isolating muscles. Common kettle bell lifts also tend to work muscles through a longer range of motion, which improves flexibility.
So while barbells and dumbbells are certainly good free-weights, keep in mind that the unique unwieldiness of kettle bell training is precisely the reason many athletes use them today. Many of the most common kettle bell exercises, such as swings, cleans, windmills, and snatches, really work the hips, hamstrings, glutes, and waistline.
Combined with proper nutrition, KB workouts will burn off fat better than almost anything you can think of. I am not aware of any reported serious injuries, but you sure wouldn’t want to bonk yourself on the head or drop one on your foot.
Ideally, some sessions with a competent instructor is a good way to go, although I've seen some excellent video instruction, too. Either way, once you know and practice proper form, kettle bells are certainly no riskier than lifting other free weights such as barbells and dumbbells.
Good judgment is the key to safe, successful kettle bell training, just as it is with barbells and dumbbells. Then begin with modest efforts, perfect your form, and gradually work up.
Next, you must consider your present strength and fitness level when deciding what weight to start with. Most of the companies selling KB's offer beginner guidelines for what weight(s) to buy.
As your strength grows you can buy a heavier bell and sell the lighter one or keep it for higher repetition work. Best of all, if you can attend a KB training workshop before you buy, or find a trainer nearby, you can try out different weights at the same time you are receiving some coaching.
There shouldn’t be ridges in the handle and the finish should be fairly smooth but not slick. But I will say that some kettle bells I've seen in department and sporting goods stores appeared to be second rate.
If you do not have a piece of equipment you trust or enjoy working with If it will affect your ability to work out correctly and you will end up not using it over time or will simply be unable to because of the physical deterioration of you or the bell. Make sure that you check descriptions on kettle bells for them to say 'Single Cast' or 'Single Piece Casting', you might also consider looking at the images very closely to see if you can tell welding around the base of the handles where the handle meets the ball of weight.
It is very important to look for kettle bells with lifetime warranties in case anything ever happens to the bell you can get it replaced. One of the best ways to determine how the paint holds up is to look through reviews on a website, this is usually one of the most important things to lifters so verbiage about how previous customers have experienced the paint should be evident in reviews.
This is fairly common in some well known brands, but if it is inserted you risk the insert coming out and then the service of the bell being uneven which will be very uncomfortable on your arms when you do any movement that involves contact with the body of the bell. This can be hard to tell looking at product images at the web, but if you have ever picked one up at the gym with a seam you can tell the difference.
Default to reviews as well for these but these you should be able to tell more if a website has detailed product images you can zoom in on and look at imperfections in the cast. A good textured or drippy paint on a smooth cast is ideal.
This creates a uniform feeling and training experience as you move between different weights. Generally speaking, everything mentioned above is important for competition kettle bells as well with a few exceptions. Paint is less important on competition kettle bells because the handle should always be bare steel in order to hold chalk and not be as tough on the hands.
Competition kettle bells are designed for high repetition workouts getting into the high tens and hundreds of reps and a bare steel handle is easier on the handles during tons of reps. In competitive kettle bell lifting the bells bang together a lot so there is not a focus on the durability of the paint.
Most competition style kettle bells in the United States including our Steel Standard Kettle bells are a steel shell and then have fillers tightly packed to achieve the desired weight while maintaining the same size and dimensions regardless of weight. The cost is able to be kept down because it is the same amount of steel in every bell and more fillers to gain the weight.
The other way to manufacture competition kettle bells is cast as a solid piece of steel. In order to maintain the same size and dimension regardless of the weight, the steel is poured into the handle and the top of the bell.
This creates a unique feeling of balance as most of the weight is in the top of the bell so it can sit in the rack and overhead position more comfortably. If you are considering competitive kettle bell lifting you definitely need a competition style kettlebell, but they are also great for high rep workouts involving snatches, jerks and clean and jerks.
They might look like iron casts with handles, but they are the most efficient type of workout equipment you can have in your collection. Ever since its invention in Ancient Greece, Kettle bells have been known to offer numerous health benefits like encouraging core stability.
However, for you to experience the countless benefits kettle bells have to offer, you need to use the right weight when exercising. For men and women who are active and athletic, the kettle bell weight they should purchase should be higher.
Therefore, make sure that before you buy any weight kettle bell, the handle has undergone flashing. Handling flashing is the process of filing down the hands’ underside, leaving the surface smooth.
If it has sharp edges, don’t purchase it as this can injure your hands as you work out. If it’s uncomfortable or too tight when you place both hands, don’t buy that dumbbell.
Be careful in purchasing plastic kettle bells, they may appear like the best option because of their affordability, but they do come with their drawbacks. Starting with one kettle bell allows you to master proper form and technique for each exercise.
The primary reason why experts recommend the use of one kettle bell is because it fully integrates your body during every workout. However, once you can comfortably perform the proper technique and form for each exercise, you can add the second kettle bell.
Therefore, make sure you don’t bite off more than you can chew when choosing the kettle bell weight to purchase. In today’s world we spend the majority of our days doing things in front of us with terrible posture.
Cubicles) for hours at a time not moving and making the front of our body even tighter. If You’re Not Doing The Kettle bell Swing, You’re Destined To Stay Fat, Tight & Weak For The Rest Of Your Life!
This overuse of the muscles on the front side of our bodies is called “anterior dominance” and it is plaguing our society. Anterior dominance results in imbalances in our muscles causing us to move and perform at sub-optimal levels.
And because of our terrible posture — because our anterior muscles are shortened and tight pulling us forward — we give the illusion of being weak and unconfident as opposed to standing erect with our chins up. It’s no wonder that we’re generally unhealthy compared to previous generations that didn’t live a convenience lifestyle in this information age.
And there is one exercise — that if you incorporate it into your daily routine — can easily combat the ill effects of anterior dominance and the Western Lifestyle. FrequencyExercise TypeIntensityRepetitionsRest up to 7x per week strength training high intensity varies by workout varies by workout Once labelled “hard core”, kettle bells are now popping up in every gym, garage and backyard because of their portability and reputation for fast results.
Go into any gym and you’ll see inexperienced exercisers turning a swing into a front squat and shoulder raise exercise further tightening our hips, quads, chest and shoulders and just adding to the anterior dominance issue that I told you about above. A hip hinge — like a dead lift movement — forces you to use those posterior chain muscles to move the kettle bell.
It will allow you to loosen your tight hips and strengthen your butt so that you’ll develop the rear end of an athlete. It will bulletproof your low back by creating an armored brace around your midsection, and it will get rid of that paunchy gut.
“If You’re Not Doing The Hard style Kettle bell Swing, You’re Destined To Stay Fat, Tight & Weak For The Rest Of Your Life!” As opposed to starting your set of swings from the standing position like how you see most amateurs do it, the hike pass allows you to overstretch your lats — a powerful muscle in your upper body with a direct relationship with your glutes — and get more “juice” out of your swing.
Push your hips back keeping your butt high and bend your knees slightly. Always making sure your shoulders stay above the level of your hips, “hike pass” the kettle bell through your knees by contracting your lats.
When you push your hips back keeping your butt high and your shins vertical, you are hinging. This is good because most people today are hip flexor and quad dominant (your anterior muscles), so learning how to load and use your posterior chain creates a natural balance between front and back that will help in preventing knee and hip issues.
Imagine that you are growing roots through your feet and grab the ground with your entire foot. Getting proper instruction from an expert so that you can MASTER THE KETTLEBELL SWING is the best thing that you can do for your training regardless of your goal.
If you want to build strength, kettle bell swings will forge a grip of steel and will add pounds to your dead lift & squat. If you want to boost your athleticism, kettle bell swings will make you more powerful and add height to your jump and shave seconds off your sprints.
If you want to pack on muscle, swinging a heavy kettle bell will build an intimidating upper back & set of shoulders. And if you want to shed body fat, swings will incinerate blubber like butter melting in an iron pan.
You’ve breached the barbells and dominated dumbbells, but if you’re still steering clear of kettle bells you’re missing out on arguably the best burn at the gym. Think about a baseball bat, says trainer Jason C. Brown, creator and owner of certification program Kettle bell Athletics.
“Kettle bells create a longer lever arm, which requires you to use more force to move an equal weight the same distance,” Brown says. This recruits more muscles, challenges inter- and intramuscular coordination, and generally delivers one hell of a burn.
But resistance is assistance, so going too light or too heavy can compromise technique — not to mention increase your risk of injury with the added momentum of most moves, Brown adds. The general rule of thumb is the more joints involved, the heavier the kettle bell weight you can use.
The dead lift is a multi joint move, so the average guy can probably handle 32 kg/70 lbs here to start, Brown says. Not only are your shoulders and abs working hard to keep you stable, but there’s more challenge to your grip since all the weight is in one hand.
“Most use a goblet squat solely as a mobility exercise — they get low and do a hip pry. “It teaches a powerful hip snap and can be a great bicep and PEC builder — but it’s difficult to master the clean unless you really have your swing dialed-in,” Lopez says.
Turkish Get-Up This move involves a lot more than just lying down and standing up with a weight overhead. “The get-up is known in most training circles as the perfect exercise because the whole move — all 14 steps — includes every possible human movement pattern,” Lopez explains.
Lopez actually makes clients ace all 14 steps while balancing their shoe on their fist before they’re allowed to try it with a kettle bell (you can opt for a two-pound dumbbell to save face at the gym). When you feel confident that you have the form down sans resistance, reach for a 12 kg/26 lb kettle bell.
Since form is so imperative here, Lopez says you shouldn’t move up a weight until you’re able to maintain perfect vertically with your arm, keep the elbow fully locked throughout all 14 steps, and feel comfortable going slow (most people rush due to discomfort). But because it doesn’t require swinging momentum or extension, a carry has a lower risk of injury than other kettle bell moves, which means you can go a bit heavier.
Grab a kettle bell that’s the equivalent of half your body weight to carry in each hand, Brown recommends. These kettle bells come in different weights and you can make use of these equipments as you do lunges, shoulder presses, and lifts.
The kettle bell workouts get your heart pumping and are quite beneficial in burning calories, offering body flexibility and many other things. Kettle bell exercises mostly targets areas like the core, arms, glutes, legs, and back.
These kettle bells come in weights that range from 5-100 pounds and you can purchase them from sporting goods stores or from online retailers. There is a short review of research on kettle bell exercises that teaches about some workouts and its benefits.
Kettle bell exercises stimulate an incredible amount of abdominal contraction because of their explosive conditioning movements. The abdominal contraction along with coordinated breathing offers quite a high level of conditioning that actually has made kettle bells popular among athletes and fighters.
In one study there was absolutely clear evidence of some effective positive changes in cardiovascular health from kettle bell exercises. Since there are several kettle bell exercises which we do with our arms in an overhead position, the muscles that are responsible for assisting our breathing process are pretty engaged in the muscular activity; thus not allowing them to assist in the process of respiratory.
This in turn forces the muscles that are most responsible for the breathing process to play an even higher role in the cardiovascular health. They also enable you for increasing your strength and building up speed and also your endurance levels simultaneously.
The first thing that must be kept in mind is that your entire back and abs remain absolutely straight. Most physical therapists value these exercises because they teach us to move in a better, stronger, and a safer way.
Kettle bell exercises help you build powerful forearms and also improves your grip. Moreover, such exercises also allow you to devote your attention towards your skill, strategy, rest and recovery.
The workout gets your heart pumping and uses up to 20 calories per minute: about as much as running a 6-minute mile. Buy a DVD or sign up for a kettle bell class at the gym to learn how to do the moves safely.
It won’t take long to understand why celebrities like Jennifer Aniston, Jessica Biel, and Katherine Hall are huge fans of kettle bell workouts. You’ll work up a sweat doing a series of fast-paced cardio and strength-training moves like kettle bell swings, lunges, shoulder presses, and push-ups.
Most kettle bell workouts include squats, lunges, crunches, and other moves that work your abs and other core muscles. The kettle bell is used as a weight for arm exercises like single-arm rows and shoulder presses.
Lunges and squats are among the most popular moves in a kettle bell workout. Your tush will be toned by using the kettle bell for added weight during lunges and squats.
Using a kettle bell for a dead lift helps tone your back muscles. The kettle bell is an effective weight that will build muscle strength.
You may want to buy DVDs or sign up for classes to learn the basics of a kettle bell workout. Yes, if you take a class or pick a DVD that's for beginners and use a lighter kettle bell.
Depending on the program, you may be getting both your strength training and your aerobic workout at the same time. If you choose a kettle bell that is too heavy or if you have poor form, you are likely to lose control of it.
This can lead to a serious injury to your back, shoulders, or neck. Start out with an experienced trainer who can correct your technique before you hurt something.
Adding a kettle bell to your existing workout is great if you want to burn more calories in less time. This type of high-intensity workout is not for you if you would rather do a more meditative approach to body sculpting, or if sweating isn’t your thing.
With your doctor’s OK, you can include kettle bells in your fitness routine if you have diabetes. Muscle burns energy more efficiently, so your blood sugar levels will go down.
Depending on the workout, you may also get some cardio to help prevent heart disease. Using kettle bells in your workout puts some serious demands on your hips and back, as well as your knees, neck, and shoulders.
If you have arthritis or pain in your knees or back, then look for a less risky strength-training program. If you have other physical limitations, ask an experienced instructor for advice on how to modify your workout.
If you worked out with kettle bells before becoming pregnant and are not having any problems with your pregnancy, then you will likely be able to continue using them -- at least for a while. Talk to your instructor and your doctor; they might suggest switching out your kettle bells during your last trimester.
