Stand with feet shoulder-width apart holding a dumbbell. Begin by slightly bending your knees as you lower into a squat position while keeping your chest up and core tight. As you descend, simultaneously hinge your hips backward (like a good morning) while allowing your torso to lean slightly forward in a controlled way. Keep your spine neutral and weight centered through your heels. Lower until your thighs are at least parallel to the floor (or as mobility allows), then drive through your heels to stand back up. As you rise, extend your hips and return to an upright position, squeezing your glutes at the top.
