Lyle Mcdonald's Generic Bulking Routine

[Justin]

I was wondering about this workout program, I understand big muscle group body lifts, or full body lifts, get the GH pumpin and shit,

But with this routine, am I looking at getting full legs and full upper body, but not much focus on the arms?

It barely hits the bi's and tri's.

Am I supposed to add more of them myself?

Does anyone have any recommendations?

Appreciate it.
