The kettlebell swing is not a squat. This is the single most important thing to understand before you start. It's a hip hinge -- an explosive movement where the hips drive back and snap forward, projecting the kettlebell with momentum. Master the hip hinge and the swing becomes intuitive. Skip it and you'll hurt your lower back.
The Hip Hinge: The Foundation
Stand with feet hip-width apart. Push your hips back until you feel a stretch in your hamstrings. Your back stays flat (neutral spine). Your shins are near-vertical. This is the hinge position.
Practice the hinge with a dowel rod along your spine: three contact points -- back of head, between shoulder blades, and tailbone. If all three stay in contact as you hinge, your spine is neutral.
The Swing: Step by Step
Setup
- Feet slightly wider than shoulder-width, toes turned out 15–30 degrees
- Kettlebell 12 inches in front of you
- Hinge to grip the handle -- both hands, overhand grip
- Shoulders packed down, lats engaged (like you're bending the handle in half)
The Hike
Pull the bell back aggressively between your legs. The bell should pass behind your heels on the backswing, not simply drop. This loads the hamstrings and creates the stretch-shortening cycle that powers the swing.
The Drive
Snap the hips forward explosively. Glutes squeeze hard at the top. Core braces. Do NOT pull the bell up with your arms -- let the hip drive project it.
The Float
At the top, the bell floats briefly at chest to shoulder height. Arms are relaxed -- they're just guiding the bell, not lifting it. If your shoulders ache after swings, you're muscling the bell.
The Return
Let the bell descend, hinge back aggressively as it reaches waist height, hike it behind you, and repeat.
Common Mistakes
- Squatting instead of hinging: Knees bend too much, the movement becomes a squat with a swing attached. Hips go back first, not down.
- Rounding the lower back: Caused by not loading the hips properly on the backswing.
- Arms pulling the bell: Generates rotator cuff stress and reduces power transfer.
- Short backswing: Not letting the bell travel behind the heels limits the power you can generate.
Programming the Swing
Beginner: 5 sets of 10 reps, 90 seconds rest. Focus on technique for 4 weeks before adding load.
Intermediate: 10 minutes continuous at a 1:1 work-rest ratio (swing 10, rest 10 seconds). This is the Russian kettlebell classic protocol.
Advanced: 100 swings for time. Track your time and try to improve it monthly.
Starting weights: 12–16 kg for women, 16–24 kg for men.
