Hi Candice,
Well, the rotation that I am currently following alternates barre/pilates/fusion type workouts every other day with an intense cardio workout. Maybe your rotation could look something like this:
Monday - Barre
Tuesday - Cathe Cardio w/intervals
Wednesday - Barre/Fusion/Ballet
Thursday - off
Friday - HC w/ Exhale Core Fusion
Saturday - Cathe Cardio or Exhale Cardio
Sunday - off (or maybe an HC workout and a walk)
I am not an HC expert, although I do have those workouts, and I know that the Getting series is short, so I would either do 2 of those at 20-25 minutes each, or I would do one and tack on another 30 minute workout. To see progress with those, you probably want to do them twice a week.
This is assuming you have 45-60 minutes per day to workout.
I think you want to do intervals at least once a week to have at least one good fatburning workout that increases your cardio capacity and endurance. You can combine HC and the Core workouts to get one good day of core and bodyweight workouts, and your barre/fusion workouts should add strength work that would also get your heart rate up a little bit.
Also, if the weekends tend to be times when you're not quite as clean with your diet, then you probably want to try to make at least one of those a workout day instead of a rest day. I always workout on my cheat day, and if I take a rest day, I eat super clean that day since I won't be burning any more calories. Also, if I was going to only workout 5 days a week, I would probably try to be more active and add a walk or something on the second day off, but that's coming from someone who usually does 6 days a week. However, since weight loss is your goal, you might find that adding a 6th day of walking would be a good addition to your plan.
I am sure you will get other ideas and feedback from other Cathletes as well.
