Here are two possible rotations (that work from larger to smaller muscle groups during the week, avoid using the same muscles on back-to-back day: as targeted muscles or assisting muscles, avoid step two days in a row or core two days in a row):
A 4-5 day workout rotation:
Day 1: HIS/Chest and back
Day 2: KB/Legs and core
Day 3: BC/Biceps and triceps
Day 4: other cardio
Day 5: LIS/shoulders,core and calves
Take 1-2 days off, then start over
(another option: do workouts in this order, with a day of rest or cardio in between)
Day 1: KB/Legs and core
Day 2: HIS/Chest and back
Day 3: off
Day 4: LIS/Shoulders/core and calves
Day 5: off
Day 6: BC/Biceps and triceps
Day 7: off
