Barbell Reverse Lunge

Stand in a shoulder-width stance with a loaded barbell resting across your upper back. With palms facing outward, pull the bar down while squeezing your shoulder blades together for stability. Push your chest out and take a large step backward, lowering your rear knee toward the ground while keeping your front shin as vertical as possible. Pause, then push yourself back to the starting position by driving through the front heel and bringing feet to meet each other.
