Before the first rep
How to set up
- 01
Place the bell. Set the kettlebell on the floor about a foot in front of your toes, so you and the bell form a triangle.
- 02
Stance. Feet about shoulder width or a little wider, toes turned out slightly. You need room for the bell to pass between your thighs.
- 03
Hinge down. Push your hips back with a soft knee bend and a flat back until you can reach the handle. Shins stay close to vertical; this is not a squat.
- 04
Grip and tilt. Grab the handle with both hands, overhand, and tip the bell back toward you so the handle points at your hips.
- 05
Set your shoulders. Pull your shoulders down away from your ears and tighten your lats, as if squeezing oranges in your armpits. Take a breath and brace.
Step by step
How to do the kettlebell swing
- 01
Hike. Pull the bell back between your legs like a football snap. Keep it high, with the handle passing above your knees and your forearms meeting your inner thighs.
- 02
Snap. Drive your hips forward hard and stand up fast. Your arms stay straight and loose; the hips do the lifting.
- 03
Stand tall. At the top your knees are straight, glutes squeezed and abs braced, like a standing plank. Breathe out sharply as you lock out.
- 04
Float. The bell rises to about chest height as an extension of your straight arms, then floats for a moment. Do not pull it higher.
- 05
Wait, then hinge. Let the bell fall back toward you. Stay tall until your upper arms meet your ribs, then hinge and guide it back between your legs into the next rep.
- 06
Park it. After the last rep, let the bell swing back one more time, then lower it to the floor in front of you with a flat back, the same way you started.

Common mistakes
Squatting the swing
Push your hips back, not down. Your knees bend a little, but your shins stay near vertical and your chest leans forward over the bell.
Lifting the bell with your arms
Keep your arms straight and relaxed. If the bell only gets to chest height when you front raise it, snap your hips harder or use a lighter bell.
Leaning back at the top
Finish tall with your ribs down and glutes squeezed. Your body should be a straight line, not arched behind your hips.
Hiking low toward the knees
Keep the bell high in the hike, close to your groin. A low hike drags your torso down and puts the strain on your lower back.
Hinging too early
Wait for the bell to fall back to you before you hinge. Bending over to chase it shortens the swing and tugs you forward.
Rounding your back
Keep your back flat and your neck in line. If your back rounds in the hike, the bell is too heavy or you are reaching too far.
Stay safe
Swing with clear space in front and behind you, a dry grip, and a bell you can control for every rep. Never let go of the handle on purpose. When your form slips or your grip starts to go, finish the set by letting the bell swing back one last time and parking it on the floor in front of you with a flat back, instead of stopping it at the top or dropping it. Expect to feel your glutes and hamstrings; if you feel sharp pain or a strain in your lower back, stop and check your hinge before adding reps, and see a coach or clinician if it keeps happening.
Programming
Sets, reps and how much weight
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Power | 5 to 10 | 5 to 10 | 50–65% 1RM | 1 to 2 min |
| Endurance | 3 to 5 | 15 to 25 | 35–50% 1RM | 1 to 1.5 min |
| Technique | 5 to 10 | 5 to 8 | 30–45% 1RM | 1 min |
Plan your next session
Put in a recent set. You get working weights for your goal, a warm-up and the plates to load.
Estimated 1RM 216 lb
Endurance sets
76–108lb
3 to 5 sets of 15 to 25 reps, 1 to 1.5 min rest. A moderate bell for conditioning. End the set when the bell stops reaching chest height or your back starts to round.
Estimates use the Epley formula and work best from sets of 3 to 8 reps. Treat them as a starting point and adjust by how the first working set moves.
Questions
Kettlebell Swing questions
What muscles do kettlebell swings work?
Mainly the glutes and hamstrings, which drive the hip snap. Your lower back, abs and lats hold your position, your quads straighten your knees at the top, and your grip works the whole set.
Russian vs American kettlebell swing: what is the difference?
The Russian swing stops with the bell at about chest height; the American swing carries it all the way overhead, with the bell bottom pointing up. The Russian version is usually taught first because it keeps the focus on the hip snap and needs no overhead mobility. The American version is a longer path, usually done with a lighter bell, and suits people with full, pain free overhead reach.
Should I feel kettlebell swings in my lower back?
You should mostly feel your glutes and hamstrings. A bit of back muscle fatigue is normal, but pain or a strain in your lower back usually means you are squatting, hiking low, rounding or leaning back at the top.
Are kettlebell swings a squat or a hinge?
A hinge. Your hips move back and forward while your knees bend only a little. Squatting the swing turns it into a weaker leg lift and takes the glutes and hamstrings out of it.
What weight kettlebell should I use for swings?
Use a bell heavy enough that you have to snap your hips to get it to chest height, but light enough that your back stays flat. A common starting point is about 12 kg for women and 16 kg for men, or a size lighter if you are new to lifting; move up once sets of 10 look clean.
Are kettlebell swings good cardio?
Yes. Sets of 15 to 25 or timed intervals push your heart rate up quickly while still training the hips, which is why swings show up so often in interval workouts.
