LA Fitness was at our school the other day and I did their body fat tester. Turns out I have %4.2 body fat and 22.9BMI. Since I'm 5'6", 142lbs, my BMI is in the 28th percentile. I found it interesting that I should have more fat on me because having so little is the unhealthy part. It's weird because i'll eat over 3,000 calories a day and barely gain anything.
