To do the Sumo Squat with a kettlebell, hold a kettlebell in both hands and set your feet wider than shoulder-width apart. Turn your toes out slightly as you stand in a wide stance with the kettlebell hanging down in front of you.
Squat down, sitting your butt down and back. Do not let your knees cave in as you squat. Drop the kettlebell to the ground but do not round forward.
Then drive back up to standing and squeeze your glutes at the top.
