1. Start in a staggered stance, like you are about to perform a lunge (the rear foot can be elevated on a bench also) and with the front foot forward.
2. Start by bending at the knee and hip to lower your body down, always keep the front knee in line with the foot and your back straight. At the bottom of the movement, push through your heel to return to the starting point.
3. You can either hold dumbbells or use a barbell for extra resistance.
