Hello,
This strictly a heavy weights series. There is no cardio of any kind that they are filming for this series. All cardio is what you choose to do on your own and SNM has said that they will make recommendations as to what type of cardio you should do along with your weight workouts.
They created a whole STS forum that addresses all of these questions because when they first announced it there were so many questions. Check it out because they have frequently asked questions that they have answered.
The STS forum was meant to answer these types of questions because most of them have already been addressed.
