You know when you use to have pillow fights when you were a kid because you thought they were cool and your parents used to step in and break them up and tell you they weren't? Well, guess what? You were right and your parents were wrong. A good ol' fashioned pillow fight is the coolest way we know to get the blood flowing through your body, work some great muscle groups and, even, work up some sweat. This workout should be taken straight to your parents with an "I told you so" note. One small note of caution, should you get over-enthusiastic you may want to rethink the decor of the room you're exercising in. We are speaking from experience when we say that vases and small porcelain figurines do not enjoy a natural lifespan with this exercise routine in action around them.
Extra Credit: 30 seconds rest between sets.
