Kettlebell Swing

1. Stand with feet slightly wider than shoulder width, a kettlebell of 12 to 24 kg on the floor about 30 cm in front of you.
2. Hinge at the hips with a flat back and grip the handle with both hands, tilting the bell toward you.
3. Hike the kettlebell back between your thighs like a snap in football, keeping your forearms high against your inner thighs.
4. Drive your hips forward explosively, standing tall and squeezing your glutes to launch the bell.
5. Let the bell float to chest height with arms relaxed; the hips power the swing, not the shoulders.
6. As the bell falls, hinge again and let it travel back between your legs with your forearms brushing your thighs.
7. Exhale sharply at the top of each swing, inhale on the backswing, and repeat in a continuous rhythm; finish by guiding the bell back to the floor with a hinge.

Common Mistakes

• Squatting instead of hinging: bending the knees and dropping the hips turns the swing into a front raise with legs; the movement is a hip snap with shins close to vertical.
• Lifting with the arms: muscling the bell up with the shoulders caps the load and misses the point; arms are ropes, hips are the engine.
• Rounding the lower back: letting the bell drag the spine into flexion on the backswing is the main injury risk; keep the back flat and the bell high in the hinge.
• Overextending at the top: leaning back and cranking the lumbar spine at lockout replaces glute squeeze with back strain; finish standing tall in a straight plank.

Programming Tips

The kettlebell swing is a power and conditioning tool, so program it in one of two ways: heavy sets of 8 to 15 explosive swings for hip power, placed early in a session, or timed intervals such as 30 seconds on, 30 seconds off for 10 rounds as a finisher that torches the posterior chain and lungs together. It slots neatly onto the end of lower body days or stands alone as a knee-friendly conditioning session.

Pick a bell heavy enough to force a real hinge; too light and people squat and lift it with their arms. Around 16 to 24 kg suits most men learning the movement and 8 to 16 kg most women. Every rep should be a crisp hip snap with a floating bell at chest height, and the set ends the moment the snap goes soft.

Common Questions

Is the swing a squat or a hinge?

A hinge. The hips travel back with modest knee bend and the power comes from the hips firing forward, not from standing up out of a squat. If your knees drift far forward on the backswing, that is the first thing to fix.

Russian or American swing?

The Russian swing to chest height is the better default: all of the hip power with none of the overhead compromise. Take the bell overhead only if you have the shoulder mobility to finish without leaning back through the lower spine.

Why does my lower back ache after swings?

Almost always a lifting-with-the-back pattern: rounding on the backswing or pulling the bell up with the arms and spine instead of snapping the hips. Relearn the hinge with a lighter bell and let the arms be ropes, not levers.
