Many of my students are nervous about kettlebell swings—here’s how to avoid the common mistakes beginners make

Many of the students in my group fitness class are nervous about doing kettlebell swings because they don’t really know how to do them and worry they might hurt themselves.

They’re right to be wary. It’s very easy to get it wrong and strain the muscles in your lower back.

But I regularly include the kettlebell swing in the plans I create for my one-to-one students, because of the unique benefits the move offers, and because I can safely supervise and make sure they have the technique right.

ISSA-certified strength and conditioning specialist Bridget Moroney and head coach at EGYM Fitness agrees.

“The kettlebell swing is one of the most efficient exercises you can add to a workout routine. It primarily targets the glutes, hamstrings, and lower back, but your core, lats, and shoulders all kick in as stabilizers, too.

“What makes it special is that it trains explosive hip power—the kind that carries over to running, jumping and pretty much every athletic movement. It also gets your heart rate up without the impact of running, so it's genuinely useful whether your goal is strength, conditioning or both.”

Her colleague Jonah Berman, also a NASM-certified personal trainer, adds that “kettlebell swings are an amazing power-builder by forcing you to explode through your hips and glutes. Especially if you spend a lot of time at a desk, these can help keep lower back and hip pain that comes from sitting all day away.

“And because it’s so dynamic, it sneaks in a cardiovascular burn without you ever having to touch a treadmill—bonus!”

Here Moroney and Berman explain why people are often put off by the kettlebell swing, common mistakes for beginners and how to perform the move safely.

The biggest kettlebell swing mistakes beginners make

Many people wrongly assume the kettlebell swing is an upper-body exercise, says Moroney.

“The arms are just along for the ride,” she says. It’s actually a full-body move that has a crucial element—the hip hinge. This is the same movement pattern you use when you deadlift, jump or pick something up from the floor.

Not hinging properly from your hips and bending your back instead is how people end up injured, says Moroney. “Plus, if the back rounds, the load goes to the wrong place and this can strain the back. The fix is simple in theory but takes practice. Keep your chest up, push your hips back like you are trying to touch a wall behind you, and think about snapping your hips forward to drive the bell up.”

Another of the most common mistakes beginners make when doing a kettlebell swing is squatting instead of hinging, says Moroney. A bend in your knees is necessary for stability but not so that it becomes a squat.

“With a hip hinge movement, the power comes from pushing your hips back and then driving them forward explosively. When people treat it like a squat they drop their knees, lose the hip drive, and end up pulling with their lower back instead.”

The dynamic nature of swinging a weight means that some coordination and timing are needed too, to control the weight like a pendulum and maintain the rhythm of your hip swings.

“Many beginners tend to emphasize the top of the movement, leading to hyperextension [when a joint moves beyond its typical range of motion] of their lower back. This can pinch your spine and cause injury or discomfort over time. You should be stable through your upper body with your glutes and core engaged.”

How to tell you’re ready for the kettlebell swing

If you want to introduce kettlebell swings into your workouts, Morony suggests making sure you’ve mastered a few things first.

“Before picking up a kettlebell, you need to ‘own’ the hip hinge,” she says. “Here's a simple test: stand about a foot away from a wall, push your hips straight back until they touch it, and keep your spine neutral the whole time. If you can do that with control, you understand the movement the kettlebell swing is built on.

“You also want basic core stability, meaning you can brace your midsection under load without your lower back caving. If either of those feels shaky, work on those first. The swing rewards good foundations and punishes bad ones.

To improve your core stability for the kettlebell swing, incorporate exercises such as glute bridge, bird dog, dead bug and plank into your regular fitness routine.

How to perform a kettlebell swing safely

• Start with your feet shoulder-width apart, with the kettlebell on the floor about a foot in front of you.
• Engage your core.
• Hinge forward from your hips and push your hips back, grasp the kettlebell handle in both hands.
• Pull the kettlebell back between your legs, keeping your back flat.
• Drive your hips forward explosively, squeezing your glutes, to generate the momentum to swing the kettlebell up to chest height, following it with your gaze—your arms should guide the bell but not lift it.
• As the kettlebell falls, hinge at your hips and push your hips back, letting the kettlebell between your legs, ready to go straight into the next rep.
