Greg Glassman's five-test fitness competition, first published in CrossFit Journal Issue 08 (April 2003).

Perform one test per day, in order, over five days.

The tests are designed to reward absolute strength, relative strength, and gymnastic foundations, and to be "hard as hell." Each test earns 4, 8, 12, 16, or 20 points, for a total of 20 to 100. A score of 20 is a reasonably good athlete; a score of 100 is a credible claim to being one of the fittest on Earth.
