When I was in middle school and they had the Presidential Fitness Test, I was a chubby little prepubescent boy. I could barely do one pull-up, and I totally sucked in the 600 yard run. In the 6th grade, I could not run a mile at all. In the 7th grade, I could run one, but the time was 9:47. Yes, NINE 47, for ONE mile. I started jogging by myself a few times a week and then my best mile time was 6:30 in my 8th grade year.
