Stand with your feet about hip-width apart under a Smith machine bar set near the floor. Grasp the bar with both hands just outside shoulder-width, brace your core, and hinge at the hips while keeping a slight knee bend. Drive through your heels to stand up straight, lifting the bar by extending your hips and knees. Squeeze your glutes at the top, then lower the bar back down with control by pushing your hips back and bending your knees.
