The Real Benefits of Kettlebells: Strength, Power, and Fitness Anywhere

As any kettlebell enthusiast — any kettlebell aficionado — will tell you, there are many benefits to these pieces of iron.

They’ll improve your strength, cardio fitness, power, and mobility. They’ll teach you how to move like an athlete. And with kettlebells, you can train anywhere, without spending a fortune.

In this article, I’ll break down the biggest benefits of kettlebells. But I’ll also give you the lowdown on what they aren’t that great for, so you can decide if they’re the right tool for your fitness goals.

What Are Kettlebells?

If you’ve seen those weird, teardrop-shaped weights at the gym and wondered what the deal is, here’s a very brief breakdown.

Simply put, kettlebells are cast-iron or cast-steel balls with a handle on top. They were originally used as counterweights to weigh crops in Russia back in the 1700s. The Russian military later adopted them for strength and conditioning, and they’ve been building more athletic people ever since.

Unlike a dumbbell, with the weight evenly balanced on either side of your hand, a kettlebell’s center of mass is offset, down in the bell part, away from the handle.

That unbalanced design is what makes kettlebell training special. The design forces your body to work in ways other weights don’t, and it’s easy to sequence kettlebell exercises into circuits that hit both strength and cardio in the same session.

What Are the Benefits of Kettlebells?

A kettlebell is way more than a dumbbell with a weird handle.

It’s a full-on strength and conditioning machine packed into one bulbous iron orb.

Its design forces your body to work harder to stabilize, control, and move the weight. You could call it the king of functional training. And some do.

Here are the six biggest benefits of kettlebells in detail.

1. All-in-One: Strength & Cardio

Kettlebells are tremendous for hybrid training. With exercises like swings, cleans, and snatches, you can combine strength training with high-intensity cardio and get good results in both. You get better work capacity or “metabolic conditioning” and improve your general athletic performance in pretty much any physical sport (and everyday life).¹

Plenty of research shows that kettlebell training can improve maximal strength even in advanced athletes. And it’s effective enough as cardio to be considered a viable alternative to something like running for improving aerobic capacity.²

A 2010 study sponsored by the American Council on Exercise (ACE) found that a 20-minute kettlebell snatch workout burned an average of 20.2 calories per minute.³ That’s more than 400 calories, the equivalent of running a 6-minute mile, but with the added benefit of full-body resistance training.

In short, kettlebells can help you build muscle, strength, and cardiovascular capacity all at the same time. Quickly, too, which means time saved.

2. Explosive, Athletic Power

Power is strength applied quickly.

• If you use a lot of strength slowly, that’s, well, strength. Like a heavy deadlift.
• If you use that same strength quickly, that’s power, like a sprint start or an Olympic clean.

Power is what makes an athlete athletic. Traditional lifting builds absolute strength, the kind you need and use when you do a slow, heavy squat, while kettlebell ballistics build explosive power, much like with Olympic lifting.

The difference is that Olympic lifts involve triple extension (extension at the hips, knees, and ankles), while most kettlebell exercises involve double extension (extension at the hips and knees, but not the ankles).

You cannot slowly perform a kettlebell swing or snatch. It is, by definition, a fast and powerful movement. You’re training your nervous system (your CNS) to recruit muscle fibers instantly.

When a 2012 study compared kettlebell swings to traditional jump squat power training, the researchers found that both improved vertical jump height (a classic test of explosive power) similarly.⁴

That means kettlebell training is super effective for real-world and sport-specific activities that require you to use your strength quickly, i.e., power, like jumping for a rebound in basketball or tackling an opponent in football.

The hip-hinge power you get from, say, a kettlebell snatch forms the base of almost every athletic movement I can think of, from jumping to sprinting to tackling. Heck, even just picking up a heavy bag of mulch without blowing out your back.

3. A Posterior Chain of Steel

Your posterior chain (your glutes, hamstrings, and your entire back) is the engine of your body and what powers most athletic things you do. If you’re like most people in the Western sit-all-day world, these muscles can get sleepy, weak, and underdeveloped, a condition called dead butt syndrome or gluteal amnesia. Not a joke.⁵

Kettlebell training is very effective for your posterior chain, especially for hip-dominant power. Exercises like the kettlebell swing, snatch, and clean load the hinge pattern dynamically and require eccentric control, hip extension, and glute–hamstring coordination.

If we take the most famous kettlebell exercise, the kettlebell swing, as an example, it’s a pure hip-hinge movement. It teaches you to load your hips and glutes and then explode them forward. I’d say there are very few other exercises that teach this explosive hip-hinge so effectively, especially considering the low learning curve.

So what’s the payoff? You build a powerful and athletic backside, which will be a tremendous help for jumping higher, sprinting faster, and lifting heavier. It’ll also protect your lower back by making all the muscles that support it stronger, potentially improving back health.⁶

Outside the gym, too! A 2011 study looked at the effects of kettlebell training on musculoskeletal pain in Danish blue-collar workers.⁷ The group that performed swings and other kettlebell drills saw significantly less lower back, neck, and shoulder pain, with the researchers calling it a “markedly positive and rapid result on pain in our study compared with previous studies.”

4. A Strong and Functional Core

Your core’s main job is to stabilize your spine and transfer power from your lower body to your upper body (and vice versa).

I’ve waded through the academic papers so you don’t have to.^{8 9 10} Here’s what they found:

• Kettlebell training is core training. Studies using those sticky EMG pads to measure muscle activity show that swings, especially one-arm swings, fire up your rectus abdominis, obliques, and erector spinae (your lower back muscles).
• The one-arm swing adds anti-rotation power to the mix because your body has to fight even harder to prevent twisting.
• Your core muscles co-activate, meaning they all fire together to create a stiff and stable trunk. That is how your core is supposed to work in sports and in life, not just when you’re lying on the floor doing crunches.

The swing is the most researched kettlebell move, but I would think exercises like the Turkish get-up and windmills are arguably even better than swings, as they are multiplanar and require core strength and stability in multiple directions for a long time.

But activation isn’t the only thing that matters. While kettlebells are great for functional strength, they might not be the absolute best tool for every single core goal.

For example, there isn’t much research on how well swings hit the deep, internal muscles like the transverse abdominis compared to exercises like a dead bug or a good old plank.

And if your only goal is to have the thickest, strongest six-pack abs possible, you’ll still want to add some direct, heavy, loaded core work (like weighted cable crunches or ab rollouts).

That all being said, 9 out of 10 regular people would probably get most, if not all, the core training they need from a varied kettlebell protocol, especially if it includes single-arm work.

5. Grip Strength for Days

Forget those little spring-loaded grip trainers. Or actually, don’t. I exaggerated for dramatic effect. Grippers are generally better for building maximal crush strength, that short, bone-crushing handshake power. But holding onto a thick kettlebell handle for dear life during a set of 20 swings or a heavy suitcase carry will build functional grip strength and endurance like nothing else.

It really boils down to two main things: the design and the movements.

1. The handle of a typical kettlebell is thicker than that of a dumbbell or a barbell, which immediately makes your hand and forearm muscles work harder just to hold on.
2. The kettlebell’s offset center of mass pulls on your grip in weird ways, forcing the little stabilizer muscles in your wrist and forearm to either step up or fail.
3. When you’re explosively moving a kettlebell, at the top of, for example, a swing, that bell is essentially trying to fly out of your hand. Your grip has to fight that momentum, rep after rep, which is awesome for grip endurance: the ability to hold on to something heavy for a long time.

Research shows that not only elite athletes benefit from kettlebell training, grip-wise. In one study, older women with sarcopenia (age-related loss of muscle mass, strength, and function) improved their grip strength (along with several other benefits) after doing two weekly kettlebell sessions for eight weeks.¹¹

6. The Practical Perks

Let’s not forget the simple stuff.

• You don’t need a $10,000 home gym setup. A single 16 kg (35 lb) bell can provide a beginner with months of workouts. Add a few bells of different sizes, and you’re set for life.
• You can use them in your living room, your garage, your backyard, or take one to the park.
• It’s a cannonball with a handle. Unless you drop it on concrete from a 20-story building, it will outlive you.
• Lastly, kettlebells are fun! And different! I’ve seen lifters who have been going to the gym on fumes and routine rather than motivation for years and years, but find new excitement in their training with kettlebells. Of course, everyone enjoys different things, so I’m not going to put words in your mouth and say that you’ll enjoy them for sure, but decades of experience tell me that people like kettlebells and the variety they bring.

What Are Kettlebells Less Good For?

Even I, who consider myself a bit of a kettlebell evangelist, will admit they aren’t the be-all and end-all. Every tool has a purpose, right? A high-performance race car is amazing, but it’s terrible at hauling lumber. You want a logging truck for that. Same idea.

The kettlebell’s greatest strength, the offset, unstable design that forces your body to work as a unit, is also its weakness for certain goals.

Here’s where the kettlebell falls a bit short.

1. They Are Not Great for Maximal Strength

Can you get strong with kettlebells? Absolutely. But if your one and only goal is to reach your absolute one-rep max (1RM) on the big three (squat, deadlift, bench press) lifts, for example, the barbell is, and always will be, the undisputed champion.

A barbell allows you to load your spine and body bilaterally (both sides evenly) with massive amounts of weight in a stable and predictable way. You cannot load a 500-pound deadlift or a 400-pound squat with kettlebells.

Progressive kettlebell training will make you strong, but the barbell and other traditional forms of strength training are the right tools for building top-end strength.

2. They Are Not the Best for Bodybuilding and Hypertrophy Training

If your primary goal is purely aesthetic and you just want to build the biggest pecs, lats, and biceps in town, or focus on bodybuilding, kettlebells are not the most efficient tool.

A bodybuilder wants to be able to isolate a muscle, control the tempo (especially the eccentric, or negative, part of a rep), and pump it full of blood to stimulate growth.

Kettlebells are designed to prevent isolation. They force your muscles to work in teams. That can be superb for muscle growth, but not if you throw the weights around like with most kettlebell exercises. Stable strength-training exercises with barbells, dumbbells, cables, or machines are better at targeting and exhausting specific muscle groups than, say, a kettlebell swing.

Now, you can do bodybuilding-style exercises like presses, curls, rows, and squats with kettlebells, but once you become reasonably strong, you’ll likely find the kettlebell versions awkward and difficult to load properly.

3. The Learning Curve for Ballistics Is Steeper

You can hand someone a pair of dumbbells and they can do a decent (if not perfect) biceps curl or shoulder press on day one.

You can’t necessarily do that with kettlebells.

To learn to snatch or clean a kettlebell safely, effectively, and quickly, you really need hands-on coaching from someone qualified. You can’t just wing it and expect good results. Or maybe you can, if you have strength-training experience, but an absolute beginner who has never touched a weight will have a harder time.

This is not really a criticism or a massive negative, as it is not hard to learn kettlebell training. The learning curve is just a little steeper than sitting down on a machine and pressing away. But the time and effort spent learning is usually well worth it.

4. Progressive Overload Can Be a Nightmare

This is a bigger, practical issue. To get stronger, you need to gradually increase the load (weight) over time.

• With dumbbells, you can go from 20 lb to 22.5 lb to 25 lb in a well-equipped gym. If you train at home, you can get a pair of adjustable dumbbells and change weights in small increments with a flick of a switch.
• With a barbell, you can add tiny 1.25 lb plates.
• Traditional kettlebells are often sold in 4 kg (8.8 lb) or even 8 kg (17.6 lb) jumps. Going from a 16 kg (35 lb) overhead press to a 20 kg (44 lb) press isn’t what I would call a “step”. It’s a 25% leap in weight and makes small, steady progress difficult. Perhaps not in exercises like the swing where you use large parts of your body, but certainly in isolation exercises for smaller body parts.

5. They’re Just Plain Awkward for Some Classic Lifts

Want to do a traditional bench press? Trying to get two heavy kettlebells into position and then stabilizing them over your chest is… a thing. The bells rest on your forearms, the offset weight is wobbly, and a dumbbell or barbell just feels 100x more stable and effective for that specific movement.

Same for a classic biceps curl. Again, you can do it, but the handle and shape make it feel unnatural compared to a good old-fashioned dumbbell.

So, yeah, you can do most regular strength-training exercises with kettlebells, and if they are the only equipment you have, you’ll get results. But dumbbells or barbells will be better for this kind of thing.

10 Kettlebell Exercises You Should Be Doing

So, how do you get all these benefits of kettlebells?

Easy: you include kettlebell exercises in your training. Here are 10 of the best:

• Kettlebell Swing: A hip hinge that builds explosive power and a backside of steel (glutes, hamstrings, back) while torching calories.
• Goblet Squat: One of the best ways to learn and perfect your squat form. It’ll hammer your quads, glutes, and core.
• Turkish Get-Up: Builds shoulder stability, a “whatever-you-throw-at-me” core, and full-body coordination.
• Kettlebell Clean: Your ticket to a bunch of other exercises (like the press). It’s a full-body exercise that teaches you how to get the bell into the rack position.
• Kettlebell Press: Pressing a kettlebell overhead is different from pressing a dumbbell; the offset weight requires more effort from your shoulder, triceps, and all the little stabilizer muscles to keep it steady.
• Kettlebell Snatch: Kettlebell power in one fluid motion where you take the bell from the ground to overhead, building full-body metabolic conditioning and an athletic physique.
• Single-Leg Deadlift: A triple whammy for balance, hamstring injury-protection, and strengthening your glutes one side at a time.
• Renegade Row: It’s a plank. It’s a push-up. It’s a row. It’s all of these things, but meaner. In a good way.
• Kettlebell Windmill: Great for shoulder stability and thoracic (upper back) mobility while giving your obliques and hamstrings a loaded stretch.
• Suitcase Carry: The definition of functional fitness. You pick up heavy things and walk, building a stronger grip, core, and traps you can hang your coat on.
