Through years of experience Greg Glassman and his wife Lauren Glassman began to develop what we now know as Crossfit. In reaction to their local "globo-gym's" strict rules and reliance on workout-machines the two eventually began training athletes their way. The goal was to forge well-rounded athletes who were superb in every physical endeavor. Their methods are simple in principle but extremely effective. Athletes are to perform constantly varied; functional movements done at high intensities.
