I am thinking of trying F7 2x/week rather than a 4 day split. I am wondering what I can expect. Also, I have been wondering, independent of the switch, if there is a reason or requirement for keeping the exercises in the order they are printed. Specifically, I have been having a devil of a time getting anywhere with RC/PE6. I've really stalled, even on the 4 day split. I am wondering if it wouldn't be wise to move that to earlier in the workout when I'm a bit fresher. I really wonder, with the switch to all 7 exercises on one day, and RC/PE6 being dead last, if this might be an issue to my progress. Thoughts?
