The average length of each routine is just under 60 minutes, with the exception of the yoga routine, which is 90 minutes. You start with routines 1-6 for the first three weeks (strength day one, three and five and cardi/stretching on two, four and six), do cardio and stretching in the fourth week, perform a different set of routines in weeks five-eight,  cardio/stretching week nine, and cycle through two weeks of the original routines, then two weeks of the same routine in weeks five-eight. Then the cycle starts over again with more weight and reps.
