Kettlebell swing
The kettlebell swing is a dynamic, explosive hip-hinge exercise that primarily targets the posterior chain. It builds power, strengthens the glutes and hamstrings, and improves cardiovascular endurance.

- Stand with your feet slightly wider than shoulder-width apart, with a kettlebell on the floor about a foot in front of you.
- Hinge at your hips, bend your knees slightly, and reach forward to grip the kettlebell handle with both hands while keeping your spine neutral.
- Pull the kettlebell back between your legs to create momentum, keeping it high and close to your groin.
- Drive your hips forward explosively and contract your glutes to swing the kettlebell up to chest height, keeping your arms straight.
- Allow the kettlebell to descend naturally, hinging at the hips only when your upper arms touch your torso, and transition directly into the next rep.

Form tips
- Power the movement entirely from your hips and glutes, rather than pulling the weight up with your shoulders or arms.
- Keep your core tightly braced throughout the swing to protect your lower back from strain.
- Wait to hinge your hips until your upper arms are close to your ribs on the descent to maintain proper timing.
Common mistakes
- Squatting instead of hinging, which shifts the load from the glutes and hamstrings to the quadriceps.
- Using your arms to pull the kettlebell up, which reduces posterior chain activation and strains the shoulders.
- Hyperextending the lower back at the top of the swing instead of standing tall with a neutral spine.
FAQ
How many reps and sets of kettlebell swings should I do?
For general conditioning and power, perform 3 to 4 sets of 15 to 20 reps with a moderate weight, focusing on explosive hip extension.
How high should I swing the kettlebell?
For the standard Russian style, the kettlebell should reach approximately chest or shoulder height. Do not force it higher using your arms.
Is the kettlebell swing safe for the lower back?
Yes, when performed with correct hip-hinge technique, it strengthens the lower back. However, rounding the spine or squatting can cause lower back strain.
