Thanks for the input, I did back today and used the assisted machine 4x8. I also included the lat pulldown and close grip cable row. I can feel that worked the lat today.

I should have continued with assisted machine when I started I just might be doing them right now. Does anyone see an issue working the back twice a week? I believe it is a large enough muscle group that it should not be a problem. Look forward to the input everything everyone has supplied is a great help to me.
