If you are doing DC with CBL I would suggest the hiit post workout or possibly before. Would be a good idea to check into an article he wrote before you decide to do before. But he does say that women can do hiit post workout because they can hang onto glycogen more than men. So the hiit can help deplete you if the volume isn't enough.
As far as specific you could do a row machine for upperbody days when you would be doing chest, shoulders, triceps, and back.
Personally I haven't tried DC with cbl because I have been having success with his routines.
Thanks, that helps out a lot.
Actually, doing HIIT after my workout would fit better my routine, just wanted to make sure that doing HIIT would indeed hit the gap for glycogen (as it would be useless if glycogen was muscle specific - that was the concern).
I was doing leangains before and fasted cardio in the morning, which made me wake up at 5am every day. Doing HIIT post workout would fit my goals better.
I would switch the routine but I truly enjoy DC, I love being in and out of the gym in 30 minutes or so doing a 4day/week split and I have never seen the amount of gains I have had with DC with any other program, besides, I travel a lot so DC is one of the very few routines I can pretty much do anywhere I go.
Will start with the HIIT post workout.
