Sure! You could alternate these 2 workouts with cardio days....M: SS, T: cardio, W: PP, Th: cardio, F: SS, Sa: cardio, Su: rest, M: PP, T: cardio.....
Or you could split workouts and alternate upper and lower body days. Like:
Mon: PP upper body - 30 min cardio high intensity cardio
Tue: PP lower body - 30 min cardio low intensity cardio
Wed: SS upper body - 30 min cardio moderate intensity cardio
Thu: SS lower body - 30 min low intensity cardio
Fri: PP upper body - 30 min high intensity cardio
Sat: PP lower body...no cardio
Sun: Rest
Then the next week do SS twice and PP once.
Or:
M: PP upper body - 30 min cardio
T: PP lower body - no cardio
W: 60 min cardio
Th: SS upper body - 30 min cardio
F: SS lower body - no cardio
Sa: 60 min cardio
Su: Rest
Just some suggestions. HTH.
