I dunno, but it seems like nobody actually commented on the routine.
I'm workin on putting my own together, so I was really looking at order of days. I think it looks good (can't say I'm any better than you at this), and I might adapt it for myself.
I'll likely make Fri a day for light cardio or off. Move chest to Saturday, and do shoulders and arms Tues. I believe that would give you maximum rest for the larger work load of chest vs. arms & shoulders while hitting complimentary exercises twice a week.
Some things seem a little redundant: Can likely get rid of the shrugs on shoulder day since you'll blast your traps on back day. Lat pull downs prob won't be necessary after chins. . . I probably wouldn't go after bent & upright rows in the same workout, but If you feel up to it then go for it! For my version, I'll replace push downs with weighted dips, and remove that last arm superset all together.
Anybody with some more experience care to weigh in? I've been a total body workout kinda guy for a long time, so I'm looking for guidance as much as the OP.
