Kettlebell Swing

You hike the kettlebell back between your legs, then snap your hips forward so the bell floats up on straight arms, to about chest height in hardstyle teaching. The hips do the work, not the arms, and it trains the glutes, hamstrings and grip while getting your heart rate up.

How to do it

  1. Stand with feet about shoulder width apart and the kettlebell on the floor roughly a foot in front of you.
  2. Push your hips back, keep your back flat, and grab the handle with both hands.
  3. Hike the bell back between your legs, high up near the groin, as if snapping a football.
  4. Stand up fast by driving your hips forward and squeezing your glutes. Let your arms stay loose as the bell rises.
  5. At the top you are standing straight, with the bell at about chest height and your glutes and abs tight. Do not lean back.
  6. As the bell falls, let it travel back between your legs and push your hips back to absorb it, going straight into the next rep.

Cues

Short phrases to think during a set.

  • “Hips back, not down”
  • “Snap the hips, don't lift with the arms”
  • “Keep the backswing high near the groin”
  • “Stand tall at the top, glutes tight”
  • “Let the bell float”

Common mistakes

  • Squatting the swing, with the knees bending a lot and the hips dropping straight down. Push the hips back into a hinge and keep the knees only slightly bent.
  • Lifting the bell with the shoulders. Keep the arms loose and let the hip drive set the height.
  • Rounding the lower back at the bottom. Keep the back flat and hinge from the hips; drop to a lighter bell if it keeps happening.
  • Letting the bell drop low toward the knees on the backswing, which pulls you forward. Keep it high between the thighs.
  • Leaning back at the top to finish the rep. Squeeze the glutes and brace the abs so you end standing straight.

The short version

The swing is popular as conditioning that also trains the hips: a set of 15 to 20 raises the heart rate quickly without the impact of running, and a single bell is enough for a home setup. Programs such as Simple & Sinister build around it.

Hardstyle teaching, the style StrongFirst follows, has the bell float to about chest height. The American swing takes it overhead and is the CrossFit standard. Hardstyle coaches tend to avoid it, arguing that lifters arch the lower back to get the bell up and that the shoulders take more strain; CrossFit coaches treat it as a normal variation.

Why people do it

  • Raises the heart rate fast with no impact, useful for conditioning when running is not an option
  • Trains the glutes and hamstrings explosively with a single kettlebell
  • Builds grip endurance over long sets
  • Takes little space and suits a home gym
  • Teaches a fast hip hinge that many lifters say helps their deadlift

Drawbacks

  • Kettlebells usually go up in 4 kg steps, a large jump between bells
  • Not a way to build maximal strength; it complements heavy lifts rather than replacing them
  • The timing of the hip snap takes time to learn, and a coach or video of your own swing helps a lot

Questions

Is a kettlebell swing a squat or a hinge?+

A hinge. The hips move back and then forward, with only a slight bend in the knees.

Hardstyle or American swing?+

Hardstyle stops around chest height; American goes overhead. Coaches from the hardstyle side avoid the overhead version, saying it tends to bring an arched lower back and more shoulder strain, while CrossFit uses it as the standard.

Why does my lower back hurt after swings?+

Usually from a rounded back at the bottom, a backswing that drops too low, or leaning back at the top. Use a lighter bell and switch to dead-stop swings for a while: each rep starts from the floor, so you set the hinge fresh every time.

What weight kettlebell should I start with?+

Most kettlebell coaches suggest starting around 16 kg for men and 8 to 12 kg for women, adjusted for size and training history. The bell needs to be heavy enough that you cannot lift it with your arms.

Are kettlebell swings good cardio?+

Yes. Sets of swings with short rests raise the heart rate quickly, and many people use them in place of running or cycling.

Swaps on other equipment

Each has the glutes as its main muscle and is also a pull, on a different piece of equipment.
