Key takeaways
- Power comes from legs, hips, and core.
- The arms guide the bell instead of lifting it.
- Finish tall with feet rooted and glutes tight.
What it is
The kettlebell swing is a hip-hinge power movement — you snap your hips to float the bell to chest height, then follow it back down. It builds conditioning and posterior-chain strength with almost no equipment, and it is the foundation for nearly every other kettlebell movement.
How to do it — step by step
- Set the bell about a foot in front of you, feet roughly shoulder-width. Hinge and hike it back between your legs like a football snap.
- Snap: drive through your heels and stand up hard into a standing plank — ears, shoulders, hips, knees, and ankles stacked in one straight line. Your feet stay planted; the power goes down through your heels into the floor.
- Float: let the power from your legs, hips, and core send the bell floating to chest height. Your arms only hold on; they never lift the bell. You should feel a momentary weightless float at the top.
- Follow: do not fight the bell down. Let it fall and gather speed, keeping your knuckles at or above your kneecaps as you hinge back, and use all of that momentum for the next rep.
- Keep your eyes forward the whole time — at the top (you are in a standing plank) and at the bottom (not up at the ceiling, not back between your legs).
- Breathe with it — inhale as the bell loads back between your legs, then exhale sharply (like blowing out a stubborn birthday candle) as you snap. The sharp exhale switches on the deepest layers of your core.
Common mistakes
- Turning the swing into a squat instead of a hip hinge.
- Lifting the bell with your arms and shoulders instead of letting it float.
- Dipping the bell below your knees and rounding your lower back.
- Fighting the bell down instead of following its momentum into the next rep.
Muscles worked
- Glutes and hamstrings — the hip snap that powers the swing
- Core and deep abdominals — braced hard on the sharp exhale
- Quads and calves — driving through the heels into the floor
- Lats, forearms, and grip — guiding and holding the bell
- Upper back and shoulders — stabilizing at the top of the float
Variations and alternatives
- Single-arm (one-hand) swing: the same snap, float, follow rhythm with one side working at a time. Let the free arm move naturally and keep the hips and ribs from twisting toward the bell. Earn it once the two-hand swing feels automatic.
How to program it
Use swings for power and conditioning — short sets of 8 to 12 clean reps with full rest early on, stopping before your form breaks. In the app, swings appear in prescribed training blocks. Follow the reps and coach notes, then use your recorded results to choose an appropriate load for the next session.
The jumping-forward trick
The fastest way to learn the swing is to stop thinking about the swing. Trevor's teaching shortcut: the kettlebell swing is literally the same movement as jumping forward — except your feet stay stuck to the floor and you are holding a bell.
Try it. Jump forward ten times, then stop in the loaded position right before a jump and notice where your body is: hips back, shins fairly vertical, weight through your heels, torso tight. That exact position is the bottom of your swing. Everyone's hinge looks a little different, so find it with your own body instead of copying a picture — the jump teaches you the hinge without you having to think about hinging.
Benefits of kettlebell swings
Few movements give you this much return on one bell and a few square feet of floor. Done consistently, swings deliver:
- Conditioning — high heart rate without running or machines
- Posterior-chain strength — glutes, hamstrings, and back working together
- Explosive hip power that carries over to sport and daily life
- A stronger, more resilient core trained by the sharp exhale each rep
- Grip and forearm endurance from controlling the bell
- A self-taught hip hinge — the pattern behind deadlifts, cleans, and snatches

Let's go over the single-handed kettlebell swing, one of the best kettlebell movements we can learn. So, basically, as you can imagine, it's all the same things as the normal swing, guys. There's really nothing different, except obviously we're using one side of our bodies. There's just a couple of things to keep in mind. Number one is your free hand, right? So I see a lot of people when they first learn the kettlebell swing or the single-handed swing, they're going like this.
Now, remember what we learned in the first how to swing video? What is the kettlebell swing like, exactly? It's like jumping forward, right? So when we jump forward, do we go like that? No. When we run, do we run like this? No. Right? We usually involve our arms. When we jump forward, our arms help a lot with momentum, right? So the same thing here. Our free arm is doing exactly what both of your arms are doing naturally if you're jumping forward.
So don't just copy me. In order to figure out how your arms should be moving when you swing the bell, what I want you to do is jump forward several times, feel what your arms are doing, and apply that to this. And it should look like this. See how my free arm almost drives the movement? Just like it would if I were jumping forward. You see how my arms swing before my feet even leave the floor?
Same thing here. My arms swinging before the kettlebell even makes it up here. It's driving the movement, right? So remember, it'll take practice. It won't come instantly. You're going to have to practice, and it'll start to feel natural. And then similar to the normal swing, just some mistakes that people commonly make, again, are letting your arm go too far down. So letting the knuckles pass the kneecaps, letting the hips come forward or stay back, right?
Keeping the free arms still like this, and stopping the kettlebell from falling. Right? Remember, let it fall, let it pick up acceleration momentum, don't hit the brakes on the way down. And that's really it. If you nail those things just like a normal swing, you will get the single-handed swing down no problem. And once you do, you'll correct the imbalances between your right and left sides, which can really over time help with your back pain, even shoulder pain, lots of things like that.
And it's important when you start to get into these single-handed movements, and that's why we do what we do. That's why we do the time circuits. That's why we progress slowly in practice and expose our core and our body to this, because oftentimes single-handed swings can cause back pain, not because they're bad for your back, but because you're finally actually using your back, and you're using it in a unilateral way, right?
So you're starting to expose these imbalances between your right and left sides, heavily expose weaknesses in your core. Your core is not just your abs, it's your obliques, it's your back, your lower back, everything's involved. So this is an extremely important exercise to even everything out and actually really bulletproof your lower back. But with that being said, you have to take it easy, take it slow. So if you start to feel tightness building in your lower back, it's not necessarily that your form is off, because I've trained so many people.
Sometimes people's form is really good, but they're still experiencing the pain more often than not. You either need to slow down and or reduce the weight. So even if you do five reps, you know, on one side, set the bell down, walk around for a little bit, let the back stretch out, and then get back at it five reps on the other side. That's better than just trying to rush through power through the tightness, because the tightness will just keep building.
Oftentimes, if you give it a chance to subside a little bit, even within the same session, you'll be fine. So be wary with the single-handed swings, but know it's probably the most potent thing that you could do to bulletproof your back in the long run. Peace.
Frequently asked questions
What muscles do kettlebell swings work?
Mostly your glutes, hamstrings, and core, with your quads, back, shoulders, forearms, and grip working to drive and control the bell. The swing is a full-body movement powered by your hips, not your arms.
Are kettlebell swings good for you?
Yes. Done with a hip hinge — not a squat or an arm lift — swings build conditioning, posterior-chain strength, and power with very little equipment or space. Start light and stop each set before your form breaks.
Is a kettlebell swing a squat or a hinge?
A hinge. You push your hips back and keep your shins mostly vertical instead of dropping into a squat. Trevor's shortcut: a swing is the same movement as jumping forward, just with your feet planted and a bell in your hands.
What weight kettlebell should I use for swings?
Heavier than you would guess for most people — the hips are strong — but light enough that every rep floats from hip power alone. A common starting point is 12–16 kg (26–35 lb) for women and 16–24 kg (35–53 lb) for men. If your arms are lifting the bell or your form breaks mid-set, go lighter.
How many kettlebell swings should I do a day?
You do not need hundreds. Start with 5–10 sets of 8–12 crisp reps a few times a week and stop each set before form degrades. Quality reps teach the pattern; sloppy volume just grooves bad habits.
Russian vs American kettlebell swing — which one is this?
This is the Russian-style swing: the bell floats to about chest height, driven entirely by the hips. The American swing continues overhead, but it demands more shoulder mobility for little extra benefit — most people should build the chest-height swing first.
What is a good kettlebell swing alternative?
If swings bother your back or you are still learning the hinge, start with kettlebell deadlifts and hip hinges, then progress to the swing. Single-arm swings and high pulls are the natural next steps once the two-hand swing feels automatic.

Let's go over it. Three main things to make this simple. Let's keep it simple, not overcomplicate it. And with all these movements that we learned, just remember, don't be too robotic. Don't focus too much. Don't try to think too much about the form. Let the kettlebell teach you, but keep these things in mind that I'm about to show you. Okay? So three main things for the kettlebell swing. Snap, float, follow. Remember that.
Snap, float, follow. We're going to go over it. So number one, snap. What do I mean by that? I mean snap into a standing plank, right? What do I mean by standing plank? Is my ears are in line with my shoulders, in line with my hips, in line with my knees, in line with my ankles all the way down. That's snap. I'm snapping hard into that position, concentrating a lot of that power in my legs, hips, and core, pushing through my heels into the earth.
Okay? So my feet should not be rocking, snapping through my heels, sending power and energy through my heels into the earth as I snap into this standing plank. Okay? That's snap. Let me just show you a few swings. So you'll notice, and again, we're just going over the first cue, you'll notice when I snap, when I snap into that standing plank, my hips are not going like this. I'm not swinging the bell like this, right?
Because that would no longer be a standing plank, right? And same thing with this. I'm not doing this either, right? Because I'm not ending in that standing plank, am I? Right? So that's number one, snap hard through the legs, hips, and core into that standing plank. And then also, well, I guess this is number two, float. What do I mean by float? When you snap hard through your legs, hips, and core, the kettlebell floats as a result of this power generated by your lower body.
You're not lifting the kettlebell, you're not pulling it up with your arms, shoulders, and back. Okay? Your upper body is pretty much along for the ride, completely relaxed. Okay? Obviously, you're holding onto the kettlebell, but that's it. All the power is coming from your legs, hips, and core. So because your arms are relaxed, you're not doing this, right? You're doing this. Watch. Notice how the kettlebell floats when I snap. See, momentary float, right?
I'm not tethered to the kettlebell, keeping my arms locked out and straight, I'm not lifting it with my upper body. Okay? And then finally, number three is follow. I follow this bell, right? And then just remember some key things when you are following the bell is number one, why I say follow is because what people tend to do is try to stop the kettlebell from falling, right? So you get this sort of thing, right?
Where you're trying to control and muscle the kettlebell wrong. You snap hard, let the kettlebell float as a result of that force, and then just let the kettlebell fall. Let it pick up acceleration on the way down and follow that. Use all that acceleration for your next swing, right? So gather all that momentum, don't lose any of it, right? That's what I mean by follow. And then some key things to keep in mind is as you follow, try to keep your knuckles at or above your kneecaps, right?
To avoid dipping too low. Okay? This will teach you how to hinge without you having to think about hinging properly, right? It just kind of happens over time because you're forcing your body to stay tight here and not bending all the way over because you can see what that does to your lower back, right? So we want to stay tight here. And the way you can kind of connect all the dots in your mind is the kettlebell swing guys is no different than jumping forward, right?
It's literally the same movement, literally the same exact movement, exactly the same. I can't emphasize that enough, except your feet are stuck to the floor and you're holding onto a kettlebell. It's the same thing, same thing. It's crazy. Once you can kind of connect that in your mind, this comes really easily. Okay? So it helps to jump forward a bunch of times, you know, jump forward like 10 times, and then stop, too, in this position and be like, where am I?
What does my body want to do when I prepare myself to jump forward? That is where you should be at the bottom of your kettlebell swing, right? And everyone's body is a little bit different, right? So don't be so robotic in saying, I need to look exactly like Trevor, just find it with your body might look a little bit different, but that's fine. It looks generally the same for most people. It's a hinging motion, which comes most naturally when you do what?
You jump forward. So that's why it's good to jump forward. So you kind of teach yourself how to hinge and teach yourself where you should be at at the bottom of your swing, right? So again, you're not just kind of bending over, and you're also not squatting, right? That's another mistake a lot of people make is they start squatting, right? We're not squatting, we're hinging, right? And then remember with all these movements, all of them, they're going to take practice.
So don't expect it to come perfectly on week one. That's why we do what we do in the first couple weeks as well, to really get the gist of all this stuff and make sure that you're actually practicing the movements that the way you should be. Okay, so snap, float, follow, putting it all together. And that's it. And then another thing, another couple of things that are just important, your eyes, right?
Your eyes notice, where am I looking at the top of the swing? I'm looking forward because I have to be in this standing plank. If I go like this, am I in the standing plank anymore? No, because my ears are not in line with my shoulders anymore, right? Eyes forward. When I'm here, eyes are still forward. They're not fixed. They're also not looking between my legs. They're forward. Do you understand? Okay, straight spine, not like this, because when I go like this, then I'm not going to hinge as far because now I'm stopping my neck.
And if I go like this, then I'm going to get dizzy because I'm looking all over the place like an idiot. Okay, boom, boom, simple, forward, forward. Okay. And then last but not least, breathing. Okay, first of all, again, don't overthink this. People think they need like an in-depth tutorial for everything. How do I breathe? You should know how to breathe, right? You wouldn't be alive if you don't know how to breathe right now.
The kettlebell will teach you how to breathe. That's a beautiful thing about it too. It's because it occupies your upper respiratory muscles, forces your diaphragm to work. But just so you know, just so you can make a conscious effort, what you should be doing with your breathing is simply this, with the kettlebell swing in particular, and we'll go through the breathing with each movement, but it's the same with everything. It's just as simple as this.
When you're loading up, you breathe in. When you're exploding or deloading, you breathe out. So, for example, what do I mean by loading up? When the kettlebell is coming back at me and I'm getting ready to snap for the swing, what am I doing? I'm loading up. And then what am I doing? I'm exploding. Right? So I exhale sharply. And when you do that, when you exhale sharply, you engage the deepest layers of your core.
Okay. And that's it. It's as simple as that. And if you're like, oh, I don't know how to do that, I can't do that. Just think about blowing out your birthday candle as hard as you can. Like a stubborn birthday candle. That's it. That's how you breathe out. That's it. And then as you keep repeating this, as you practice, it comes naturally. So don't overthink it. So one more time. Listen to the breathing.
And that, my friends, is it. Hope this helps. Peace.
