The word “competition” makes a lot of people assume competition kettlebells are specialized equipment meant only for kettlebell sport athletes.
They're not.
“Competition” describes the design of the kettlebell—not the person who should use it.
In fact, many of the features that make competition kettlebells useful in sport also make them a smart choice for everyday training, strength work, general fitness, and anyone who plans to use more than one weight.
And one of the biggest advantages starts with something simple:
The kettlebell doesn’t have to completely change shape every time the weight changes.
What Is a Competition Kettlebell?
Competition kettlebells are built around standardized exterior dimensions.
A light competition kettlebell and a heavy competition kettlebell are the same overall size. The amount and distribution of material inside the bell changes to create different weights rather than simply making the entire kettlebell bigger or smaller.
That may sound like a minor detail.
It isn’t.
It solves one of the fundamental problems with traditional cast-iron kettlebell design.
The Problem With Traditional Cast-Iron Kettlebells
Traditional solid cast-iron kettlebells generally get physically larger as they get heavier.
At first, that seems perfectly logical: more iron equals a bigger kettlebell.
But your body doesn’t change size every time you pick up a different weight.
Your hands are still the same size.
Your wrists are still the same width.
Your forearms are still in the same place.
So when the entire kettlebell grows or shrinks according to its weight, the proportions can become problematic at both ends of the spectrum.
Take a very light traditional kettlebell, such as a 4kg bell. Because so little iron is required to make the weight, the entire bell can become extremely small—including the handle and the inner space created by the handle (the "window").
The window can be so cramped that you can’t comfortably put your hand all the way through the handle into a proper rack or overhead position.
Instead of the bell sitting farther down the forearm where it belongs, it may end up pressing into the bones of the wrist or even the back of the hand.
That isn’t simply uncomfortable.
The dimensions of the kettlebell can make proper hand positioning more difficult and even negate some of the benefits of using kettlebells because the mass of the kettlebell is not as offset from the handle.
Then, at the other end of the spectrum, you can run into the opposite problem.
As traditional kettlebells get heavier, the entire bell—and often the handle—gets larger. At very heavy weights, those handles can become unnecessarily thick and difficult to grip.
Now the equipment is creating a different limitation.
At one end, the kettlebell can be too small to fit the hand properly.
At the other, the handle can become so large that gripping and controlling the kettlebell becomes more difficult than it needs to be.
And at every incremental weight between the two, the bell body size changes, too.
Your technique (like timing, hand position and balance) changes with each individual kettlebell. If it takes 10,000 reps to become a master, now you need to multiply 10,000 reps x each individual weight you use.
The take-away?
Your hand didn’t change. The kettlebell did.
Competition Kettlebells Solve the Size Problem
Competition kettlebells take a different approach.
Instead of allowing the outside dimensions to be dictated entirely by how much material is required to reach a particular weight, the exterior dimensions remain standardized.
That means a light kettlebell doesn’t have to shrink into a tiny bell with a tiny window.
And a heavy kettlebell doesn’t have to become an enormous object with an increasingly oversized handle.
The primary advantage is not that every competition kettlebell is somehow ergonomically perfect.
It’s that you eliminate the extreme changes in size and proportion that happen when a kettlebell simply grows and shrinks with its weight.
And as a result, moving between weights becomes far more consistent.
Your hand goes through a familiar-sized window.
Your rack position doesn’t have to change dramatically because you moved up a weight.
Your overhead position doesn’t suddenly have to accommodate a completely different-sized object.
You’re changing the load—not relearning the equipment.
But there’s an important distinction here.
Standardized Doesn’t Necessarily Mean Optimal
A standard competition kettlebell solves the consistency problem.
That does not automatically mean its shape has been optimized for the human body.
Most competition kettlebells still use the traditional round or nearly round body shape.
And that’s where Pro Kettlebell is different.
We started with the advantages of competition-style dimensions, then asked a different question:
What if the kettlebell itself were shaped around the way the human hand, wrist and forearm actually interact with it?
That question is what led to the patented Pro Kettlebell design.
Why Does Kettlebell Shape Matter?
A kettlebell isn’t a dumbbell.
During cleans, presses, jerks, snatches, windmills and many other kettlebell movements, the bell actually interacts with your body.
Your hand travels through the handle.
The kettlebell rests against your forearm.
Your wrist, elbow and shoulder organize themselves around the position of the bell.
So the dimensions and geometry of the kettlebell can either help you find a strong position—or make you compensate for the equipment.
Traditional round kettlebells create a round contact point against a relatively flat forearm.
We knew the shape itself was part of the problem.
So we changed it.
Pro Kettlebell Takes Competition Design Further
Pro Kettlebell’s patented body geometry was designed specifically around the way a kettlebell sits against the hand and forearm.
The curves aren’t there just to look different.
And they aren’t there merely to make the kettlebell hurt less.
The armrest angle, body shape and balance are designed to help guide the hand and arm toward the proper position.
When your technique is right, the kettlebell fits against you naturally.
Like a glove.
That’s the difference between simply standardizing a kettlebell and optimizing its geometry for kettlebell lifting.
A traditional cast-iron kettlebell changes size with the weight.
A standard competition kettlebell gives you more consistent dimensions.
A Pro Kettlebell combines that consistency with a patented body shape designed for better fit, comfort, leverage and function.
Comfort Was the Goal. Control Was the Discovery.
We set out to make the most comfortable kettlebell ever.
Traditional round kettlebells can dig into the forearm, bang against the wrist, and create painful pressure points - especially during cleans, snatches, presses, jerks, and high-rep training.
So comfort was absolutely the goal.
But the Pro Kettlebell countours for your arms aren't simply shaped to reduce pressure.
Their angles are designed to guide the hand and arm into better alignment.
That alignment helps the hand, wrist, and arm find their strongest leverage - giving the lifter more control and promoting proper technique instead of forcing them to work around the shape of the bell.
So the pursuit of comfort led us somewhere bigger.
A more comfortable kettlebell became a more controllable kettlebell.
And better control means better positioning, better technique, and a better lift.
Greatest Comfort. Greatest Function. Greatest Reps. Greatest Results.
Competition Kettlebells Aren’t Just for Kettlebell Sport
The standardized competition design exists because of kettlebell sport, where athletes need predictable equipment across different weights.
But there’s nothing about consistent sizing that only benefits competitors.
Think about a beginner learning the rack position for the first time.
They’re learning how far to put their hand through the handle, where the bell should sit on the arm, how to position the wrist, and how the entire system should feel.
As they get stronger and move up in weight, why would we want the equipment to suddenly become a completely different shape and size?
Consistency can make learning easier.
It can make progression easier.
And it can make using multiple kettlebell weights in the same workout feel much more natural.
You don’t have to compete.
You don’t have to snatch a kettlebell for ten straight minutes.
You don’t even have to know what kettlebell sport is.
You can swing it. Squat it. Press it. Carry it. Row it. Deadlift it. Clean it.
Do five minutes of training with it or build an entire workout around it.
A competition kettlebell is still a kettlebell.
The word “competition” tells you where the standardized format came from.
It doesn’t tell you who is allowed to benefit from it.
Why Are Competition Kettlebells Different Colors?
Competition kettlebells traditionally use specific colors to make different weights easy to identify at a glance.
That color system is another feature that originated in sport but is incredibly practical for everyday training.
8kg — Pink or Black
12kg — Blue
16kg — Yellow
20kg — Purple
24kg — Green
28kg — Orange
32kg — Red
Once you become familiar with the system, you can walk into a gym and immediately recognize the weight you want without searching for a tiny number printed somewhere on the bell.
It also makes a rack full of kettlebells easier to organize and much easier for coaches and athletes to navigate.
Are Competition Kettlebells Too Advanced for Beginners?
Not at all.
A competition kettlebell isn't an "advanced" kettlebell. It's simply a different - and more standardized - style of kettlebell.
Beginners don't need beginner equipment. They need equipment that lets them learn good technique.
That's especially important at lighter weights, where traditional cast-iron kettlebells can become so small that the handle window itself interferes with proper positioning.
So if you're new to kettlebells, don't let the word "competition" scare you off.
You don't have to earn your way into a competition kettlebell. You just have to lift it.
What Weight Competition Kettlebell Should I Start With?
If you can only get one kettlebell, we generally recommend choosing your medium weight - a weight light enough to use for more technical and overhead exercises, but heavy enough to give you meaningful resistance for swings, squats, rows, carries and strength work.
The goal is versatility.
You don't want your only kettlebell to be so heavy that there are dozens of exercises you can't perform well with it. And you don't want it so light that it offers very little challenge for your stronger movements.
As a general starting point for one kettlebell you can use for a wide variety of exercises, we recommend:
Activity Level |
Women |
Men |
Currently not very active |
4kg (9lb) |
8kg (18lb) |
Works out weekly |
8kg (18lb) |
12kg (26lb) |
Very athletic |
12kg (26lb) |
16kg (35lb) |
If you're between weights, we generally recommend erring on the lighter side, especially when you're learning kettlebell technique. You can always make a lighter kettlebell more challenging with more reps, longer sets, slower tempos and more technical exercises.
And remember: there really isn't one perfect weight for every kettlebell exercise.
A weight that feels easy for a deadlift may be challenging overhead. That's why most people who stick with kettlebell training eventually build a small collection of light, medium and heavy weights.

So Who Exactly Are Competition Kettlebells For?
Competitors, obviously.
But also beginners.
And...
- Coaches
- Strength athletes
- Weekend warriors
- People training in their garage
- People working out for twenty minutes before work
- People who love kettlebell sport
- People who couldn’t tell you what kettlebell sport is
- People who want to get stronger
- People who want to move better
And people who simply want equipment that works well with their body.
In other words:
Competition kettlebells aren’t just for competitors.
Traditional cast-iron kettlebells allow the size of the kettlebell to be largely dictated by its weight.
Competition kettlebells solve that problem by standardizing the exterior dimensions.
Pro Kettlebell takes the next step—combining those consistent dimensions with patented geometry designed to optimize the way the kettlebell fits, rests and moves with the lifter.
Because your kettlebell shouldn’t be another obstacle you have to overcome.
That’s what the weight is for.
Ready to Feel the Difference?
The International Line Apollo Pro Kettlebell combines competition-style dimensions with Pro Kettlebell’s patented ergonomic body geometry and is the Official Kettlebell of the International Kettlebell Organization.
Competition describes the kettlebell—not the lifter. You don’t need to compete to benefit from standardized competition-style dimensions.
Standardized sizing solves the extremes of traditional cast iron. Light bells don’t shrink into tiny handle windows, and heavy bells don’t require increasingly oversized handles.
Pro Kettlebell takes competition design further. Patented angles and body geometry are designed to improve comfort, create stronger leverage, and promote proper technique.
