Fully engaging the body's front kinetic chain should, ideally, include some high-impact work, plus some closed kinetic chain ground work. Ice Age meets both of these requirements. It makes you move large muscle groups under load which means your lungs will work hard and your body's circulatory system will go into high gear. Add EC and you will find that the Ice Age workout is a challenge that cannot be taken lightly.
Extra Credit: 1 minute rest between sets.
