The Cardio Power and Resistance workout pretty much does what it says it’s going to do. It alternates between high-energy cardio training and resistance strength training, all while utilizing Shaun T’s special method of max interval training.You won’t be surprised by the way this workout starts out.

Personally this one really gets me tired and searching for air like a fish on land. It is extremely hard and will push you to your limits.
