1. Stand in spine-neutral position with feet slightly more than shoulder-width apart.
2. Hold kettlebell with one hand, palm down and arms in front of body.
3. Bend knees slightly and thrust hips back, as for a squat, but don’t go down as far.
4. Maintaining a fluid motion, drive hips forward explosively while swinging the kettlebell forwards with one hand to shoulder height, engaging hips and glutes all the time. Swing the other arm out at the same time to maintain your balance and help drive momentum. The hips and glutes, rather than your arm, should be driving the kettlebell forward.
5. Take kettlebell in your other hand after swinging it back between your legs and swing it out again, focussing on the hip thrust to power it out.
6. Repeat swinging motion for 12-15 repetitions per side, or according to your particular program and weight of kettlebell.
