There was a rotation I followed for a long while that used Slow and Heavy and one body part per day with 30 min. cardios. It worked well and I saw great strength gains while doing it.
Monday: S&H chest and 30 minutes high intensity intervals (step: Blast Mania premix off of ImaxII) and core work
Tuesday: S&H back and 30 minutes high intensity cardio (kick boxing: KPC conditioning and CK conditioning)
Wednesday: S&H Legs and Shoulders and core work
Thursday: S&H Triceps and 30 minutes of high intensity intervals ( BC cardio only premix two times)
Friday: S&H Biceps and 30 minutes cardio (Hi Lo, running or elliptical machine)
Saturday: Any circuit workout or one with both cardio and weights (CM, any Terminator workout, BC, C&W, SJP...) and core work
Sunday: rest or yoga
Here is a copy of it if you are interested. I substituted when I didn't have a particular workout. I really like this rotation and if you want or get bored with S&H she said you could sub with PS or Pyrmaids. This rotation was made up by Becky U.
Hope that helps you some!:7
