I started doing deadlifts as my main movement awhile ago, weighted chins after and my back looks better, I don't have those "ribs" showing when I spread my back or reach my toes etc, it's also harder I think. I don't even use the machines anymore, I may do the lower pulley machine or some set of t bar machine after my main basic training, but mainly because I have ectomorphs overtraining mind, other than that pulley machines are pointless. Oldschool chin ups have taken my heart.
