If you want to fully develop your back in terms of definition and detail, you have to go beyond just doing deadlifts, heavy rows and chin-ups for mass…you need to attack your lats with two distinct patterns of pulling movements…vertical and horizontal…done with strict form.
Vertical back movements consist of chin-ups, pull-ups and various forms of pulldowns. Horizontal movements are your rowing movements (in this case, horizontal means relative to the torso – a barbell row is in absolute terms a vertical path of movement as you row the bar up but the bar path itself is horizontal relative to where your upper body is positioned).
Now, most people instinctively realize this and train both patterns of movement in their back workouts…in separate exercises.
What if you could cover BOTH patterns of movement in ONE exercise…
