The human body is bi-pedal. We're just not meant to get around on all fours, which means that type of movement challenges us and it forces our muscles to work overtime. That is exactly what Power Crawl is designed to do. It's a full body workout that's designed to promote strength, agility and fascial fitness by pushing your body through some very specific ground moves. Add EC for the extra level of discomfort that you know you need.
Extra Credit: 1 minute rest between sets.
