I was thinking the same thing....
I don't know if I can explain this exercise well, but I do it at the end of a back workout and I love the feel it give me in my lats.
I use a cable crossover station . I attach the handle on the very top and grasp both of them while i stand in the middle of the apparatus. I then lower myself so I am resting on my knees(no dirty homo jokes guys!). I then pull my elbows into my lower ribs. Make sure you don't pull with your arms, rather pull with your lats. I hope I explained this alright. If not, you can always do chin-ups and pull-ups for your lats.
