Hi,
Over in the video/dvd roation forum someone answered this type of question.
Here is what they had to say:
Well, I can suggest this for good fat burning:
2 anaerobic workouts a week -- minimum
2 full body weight training workouts per week -- minimum
1 straight cardio workout per week -- minimum
1 plyometric workout per week (usually Cathe combines anaerobics with plyometrics -- the exception is LowMax) -- minimum
1 or 2 stretch workouts perweek -- can be done in combination with your cardio.
IMAX, IMAX2, IMAX3, LowMax are all anaerobic workouts, as well as plyometric workouts -- the exception is LowMax -- it does have some plyometrics, but not as much as the other IMAX's.
Muscle Endurance, Muscle Max, Power Hour, Maximum Intensity Strength are all full body weight training workouts.
Maximum Intensity Cardio is straight cardio, as are most of Cathe's step workouts. I particularly like Body Max, which is intense cardio and strength all in one.
Cardio & Weights, Bootcamp, etc are circuit workouts and give you both intensity (cardio) and strength -- and Bootcamp also gets you up into your anaerobic zone.
I hope this helps. She didn't include the Body Blast. Maybe someone else will know.
