Exercise Advice: This is the same exercise as the barbell lunges, except you are now using dumbbells. Stand up straight and hold a dumbbell in each hand, letting the dumbbells hang down at your sides. Be sure that you have enough room to perform this exercise. Begin by striding forward with one leg to execute a regular lunge while keeping the other leg set in place. Be sure to really stride forward so that you get a great stretch. Bring that leg back to the start position and repeat with the opposite leg.
