To perform a sumo squat, stand with your feet wider than shoulder-width apart, toes pointed slightly outward, holding a weight such as a dumbbell or kettlebell in front of your body at arm's length. Lower your body by bending your knees and pushing your hips back, keeping your chest upright and knees tracking over your toes. Once your thighs are parallel to the ground, push through your heels to return to the starting position, engaging your glutes and quadriceps throughout the movement.
