CrossFit Dog Fight represents the development of human performance using physical activity skills and drills essential to human energy system adaptation. Much like a Dog Fight, each person must use accuracy, balance, agility, speed, strength, and much more to beat their old, weaker, and less accurate self. It is the essence of human performance that allows us to live our lives with a much higher quality of life. Think of this dog fight as good versus evil, or new improved versus older models.
