Begin standing with your feet shoulder-width apart, core pulled in toward your spine. Hold a dumbbell in each hand, palms facing in toward your sides. Roll your shoulders up, back, and down to press your shoulder blades together. Make sure to keep this posture throughout the movement.
Keep a slight, relaxed bend in your knees and brace your core as you shift your hips backward, like you were going to sit in a chair. Lower the dumbbells toward the ground until your chest is parallel to the floor, making sure to keep your back flat and shoulder blades pulled in toward your spine, not rounded forward.
Continuing to keep your core tight, drive through your heels and squeeze your glutes to lift your torso back up to the starting position. Squeeze your glutes at the top but avoid leaning back or arching your back.
