Ha, so I am at 230Lbs with 16BF. So it is about 36Lbs of FAT.
So if 1Lb of fat - 3500 calories that means that I would have to do 600cal/hr cardio in 65% HR Zone.
This beeing said, 36Lbs x 3500 cal = 126000Cal
126000cal / 600cal/hr = 210hr
210 hr with one hr of cardio per day = 210 days
So it would take about 6 maybe 7 months of cardio and dieting everyday to loose a good amount of that!
So easy to gain it, so hard to loose it. Wow...
BTW, I don't know if this is totally right, I just did some simple math based on what I know and understand, so don't quote me on this.
