Similar to a barbell row but with the ability to also pull the weight up and out to the sides creating a great contraction in the lats. I typically use this as a supper set following another back exercise.
-Keep a neutral spine. Core tight
-Your back should be flexed and engaged the entire time
-Pull the dummbbells in line with the base of your chest
-You can change the difficulty by leaning forward more. Do not allow lower back to arch
