There's like 10 challenges including running a mile, a half basketball court relay, touching your toes (pictured), etc. There was a "great job" level and a "you did well enough to not fail" level. At my school, the great job level required you to meet a higher level at only 2 challenges and meant you got a free shirt. Other than that, there were no consequences. It was the same kids who did a great job each year, so a small subset of the class would be wearing those shirts all week, then walk home with a new one.
