dumbbell goblet squat

Stand with your feet shoulder-width apart, holding a dumbbell vertically against your chest with both hands. Keeping your chest up and core engaged, lower your body down into a squat position by pushing your hips back and bending your knees. Continue lowering until your thighs are parallel to the ground, or as low as you can comfortably go. Pause for a moment at the bottom, then push through your heels to return to the starting position. Repeat for the desired number of repetitions.
