well. i'll chime in i guess.
im 20yrs old, 6'2" , and 270lbs.
now, i know that sounds really bad, but you have to take into account that i go to the gym 4 times a week, and a lot of that is muscle, im no body builder, and im not ripped or anything, but since i started going to the gym i lost a lot of weight, then gained it back in muscle-mass. my trainer says that if i was my "ideal" weight of 185, that it would just be super unhealthy for me. however, i wouldn't mind if i could get down to say 220-240. I just have a ridiculously slow metabolism i guess which makes it exceedingly difficult.
