barbell single leg split squat

Stand with your feet shoulder-width apart, holding a barbell across your upper back. Take a large step forward with one leg, keeping your torso upright. Lower your body by bending your front knee and hip, while keeping your back leg straight. Continue lowering until your front thigh is parallel to the ground. Pause for a moment, then push through your front heel to return to the starting position. Repeat for the desired number of repetitions, then switch legs.
