I dont know if i created this excercise but i feel it works fairly well. You would use the v-bar that you would normally use for cable low rows and keeping the arms straight or slightly bent, just pull the weight by pulling shoulder blades back and together. I have been doing these recently. I go straight into them after my low row reps. Did i make a new variation or just something thats not well know, probably the latter but you should try it out and tell me what you think. Anyone else doing this or know what im talking about? Is there a name for it?
