This is a great supplemental or accessory exercise to help build your deadlift. You can use it with higher weights, working up to a heavy 3 or 5 reps. Or you can use medium weights and do higher reps.
Begin by standing between the two bars so that your toes are just behind the plates. Grab one bar in each hand. Drop your hips, arch your back and keep your shoulders back. Push your feet into the floor and stand as if doing a traditional deadlift. Squeeze your glutes at the top and slowly return the bars back to the ground. Repeat for desired number of reps.
