Kettlebell swing

The kettlebell swing trains explosive hip extension without joint compression. It is conditioning, hip-hinge practice and posterior chain strength in one. For lifters past 40 who want to keep producing power, it is one of the most useful lifts in the gym.

Setup

Stand with feet shoulder-width, kettlebell on the floor about a foot in front of the toes. Hinge at the hips, knees softly bent, and grip the handle with both hands. Pack the shoulders down, take a sharp breath, and tilt the kettlebell backward to start the first rep.

How to do it

  1. 1

    Hike pass

    Hike the kettlebell back between the legs, high enough that the forearms contact the inner thighs. The trunk hinges forward; the back stays flat.

  2. 2

    Snap the hips forward

    Drive the hips forward fast, squeezing the glutes hard. The kettlebell floats up to roughly chest height, propelled by the hip extension. The arms do not lift it.

  3. 3

    Float at the top

    At the top of the swing the body is fully upright, glutes squeezed, the kettlebell weightless for a fraction of a second. The lats keep it close to the body.

  4. 4

    Hinge to absorb

    As the kettlebell falls, hinge at the hips to absorb the load. Let it pass between the legs again, then snap the hips for the next rep.

Common mistakes

  • • Squatting the kettlebell up by bending the knees rather than hinging at the hips.
  • • Lifting the kettlebell with the arms rather than the hips.
  • • Letting the kettlebell drift away from the body at the top, which loads the lower back.
  • • Rounding the back at the bottom of the hinge.
  • • Holding the breath through the set; exhale at the top, inhale at the hinge.

Variations

American swing

Bell swung all the way overhead. CrossFit favourite. Pointless for most lifters and brutal on the lower back. Skip it unless you train for AMRAPs.

Single-arm swing

One hand at a time. Adds anti-rotation demand and surfaces side-to-side weakness. Earned after 8 weeks of the two-handed version.

Dumbbell swing

Same lift with a dumbbell held vertically. Most gyms have these. The kettlebell handle is more comfortable, but a dumbbell works.

FAQ

Two-handed or single-arm? +
Two-handed for the first 8 to 12 weeks. The two-handed swing is more stable and lets you build the pattern without an anti-rotation demand layered on top. Once two-handed swings feel clean for sets of 20, start single-arm.
How heavy? +
Start at 16 to 20 kilograms. Most lifters past 40 will reach 24 to 32 kilograms within 8 to 12 weeks. Adding weight matters less than adding speed; a 20 kilo bell moved fast is harder work than a 32 kilo bell moved slowly.
How many reps? +
Three to five sets of 10 to 15 reps. Treat the swing as both strength and conditioning. Two sessions a week, not stacked next to heavy deadlift days.
Will swings replace cardio? +
For most older lifters, yes. Heart rate climbs fast on a moderate-weight swing set and the recovery cost is lower than running. Pair them with a weekly walk and your conditioning will be better than 90 percent of your age group.
