When I first started lifting as a 15 year old 9th grader, I was 140 lbs @ 5'7. At 16, I was 190lbs.
17: 205.
18-19:215->170.
20: 185.
20-21: 185->230->200.
22: steady low 200s.
My weight has fluctuated a lot, so has my size. I don't have pictures of me at all of these ages and weights (might be able to dig some out of my parents' mounds of photos, but that's too much work). Here are some photos to show some of this.

My sister was killed in a car wreck december 15th 2001, and I lost all cares about everything, but I lifted like a mad man and got strong as hell (and FAT) over the next 3 months
