Interesting

Just for fun, and knowing that 3,500 calories = 1 lb of fat, and assuming that 50 calories (gove or take) = 1 point, I figure that I would have to burn 7,000 Activity Points in order to lose 100 lbs of fat from exercise. Assuming that I built up to the recommended 28 APs per week, it would take 250 weeks to earn 7,000 APs. That's almost 5 years.
