Dumbbell Sumo Deadlift
Here is a you tube video from Kiefer, demonstrating a dumbbell sumo deadlift. You can also do this same movement with 2 dumbbells, you would simply hold them together between your knees. In the video she moves from weight to weight. This is a good way to perform a drop set at the end of a workout. This is a good option if you are forced to deadlift without a barbell.
