Position yourself for this exercise by standing with your feet at a one-shoulder widths distance from one another with a barbell across your upper back. In order to execute the movement, step forward with one leg and flex your knees in order to drop your hips. Descend in this manner until your rear knee almost touches the ground. Throughout the movement, ensure that your head is up and that your back is kept completely straight. Once your rear knee is just above ground level, press through the heel of your front foot in order to extend both knees in such a way so as to raise yourself back up. Step forward with your rear foot and repeat this movement on the opposite side. Repeat for the prescribed number of repetitions.
