You can do it days apart. It works:
GGGOOOO or GOGOGOO or GOOGOOG and still at least have 3/7. For physical therapy, 1 day a week is bare minimum so the things you're concentrating on, repeat them at least once a week, they don't have to be contained on that one day.
The separate muscle group days prevent you having to work the same sore muscles again the next day but if you're not sore in two days, then you can repeat.
You're doing it right if you're still sore on the 4th day after the workout but not sore on the 5th so a GGGOO schedule repeating is the fastest cycle you want. Don't exercise sore muscles, they're still repairing.
I've had a few leg days that were still sore the 6th day, I hit them too hard, that's not good either. Worse even than only being sore one day. You don't have to be so strict.
