{edit} Well, there's just no way to make that look good. So the minimum standards for a 17-26 year old male are 3 pullups, 50 abdominal crunches and a 3-mile run in 28 minutes. Note that these minimums leave the Marine 30 points shy of a minimum total score so he'd better pick up some points somewhere. Max scores in each category are 20 pullups, 100 crunches and 3 miles in 18:00.
