Stand with your feet spaced at shoulder width and squat down to pick up the kettlebell with both of your arms fully extended.
Start by hinging your hips and bending the knees slightly to lower the kettlebell, then explosively extend the hips and straighten your legs to raise the weight up to roughly shoulder height. Allow the kettlebell to swing back down between your legs. Keep your back straight and arms fully extended throughout the movement. Repeat for the desired amount of repetitions.
Avoid rounding your back during the exercise.
Fitness for all, for life.
