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.

IMO it depends on your level of fitness. I know a lot of people who do a 3 on/1 off split and get great results. I do 4 and 1 myself right now simply because I just can't seem to fit shoulders in with anything else.

But yes, I think you can do back twice a week, especially when 'on'. I know you said you just hit PCT but you should still be able to go 2x a week. The best thing is to give it a shot, see how you feel, and adjust accordingly. If you went Mon/Fri and felt good on both days you could keep it up. If you feel over trained you may want to go every 5 days, so it would be Mon/Fri, then Tues/Sat the next week, etc.

When you train back, how many sets do you do? To me, that would have a part in how often you train back.

Myself, I train back once a week but do 17 to 18 sets over 5 different exercises. IMHO, at least for me, 17 to 18 sets of back twice a week would be too much.

Like biggin said, won't hurt to give it a try and see how it goes.

JMO....

I did back today took the advice and used the assisted pull up machine, incorporated pull down exercise (lat pulldown today) and did the close grip row as always. I definitely know I worked it not sure if it was the pull down or assisted pull ups. I am kicking myself in the ass for not keeping the assisted pull ups from day one as well as the lat pull down. I guess I did too much reading. Going to keep it to the basics.

One last question I am going to do back twice a week based on the input as well as increase the rep range. I just do not want to sacrifice weight for reps. I believe I should go heavy during the PCT. Can anyone suggest a 2 day back routine confirm and how would you break out the exercises over the 2 days knowing what my goal is. Thanks to all again love the input keep it coming.

me personally i wouldnt like to train back twice week but may work for you i done this for arms when thought wasnt growing and found training twice week hindered them but as said could work well for you
if i did would keep it simple
day 1
latt pull down
close grip cable row
barbell row
deadlift
day2
pull up (assisted if needed)
dumbell row
hyperextension
invereted body row
this doesnt include traps
