Select a medium to heavy kettlebell; 15 kilograms (about 33 pounds) should be a good start, but feel free to go lighter or heavier. There should be about half a foot of space in between your feet.
With your core engaged and your back flat, grip the handle of the kettlebell with both hands, holding it in front of you with your arms fully extended.
Engage your core as you shift your hips backward, like you are going to sit in a chair, lowering the kettlebell down to the ground. Be sure not to round your back.
Still engageing your core, drive through your heels and squeeze your glutes as you lift up.
