I would try whichever rotation has the greatest amount of videos that you haven't done in awhile. This will 'shock' your system and allow to do bust any current plateaus. Also, I would also suggest doing each rotation for at least 4 weeks. This will allow you to see if it is working or not, and it will also give you time to progress and learn which part of the rotation you'd like to modify (adding more cardio, adding more ab work, making workouts shorter, etc.) I really hope this helps and have fun with your baby!
