At first I thought your post sounded a little condescending and judgmental ("I don't see why you would want to be that huge", like a *****y girl might claim, etc), but when I re-read it, I realized that it can be an open-minded question where you are seeking an honest question without making judgments. Darn internet doesn't always convey correct emotions, lol.
Maybe I'm used to some jealous guys trying to shoot down people's choices in life, girls shooting down skinny girls, or old people shooting down stuff like tattoos, etc, lol - no offense....unless you're old.
I'm roughly (or smoothly) 6' 200lbs ~10% bf. (Guessing at bf, haven't bothered to measure anymore. I only care what it looks like in the mirror/on camera, not the number. Wish I could say the same for weight, but hate seeing that number go down, lol). My endurance is great and my agility is quite good. Well, I say that until I see some of the high-flying wrestlers on tv, lol. I can't do a standing back flip.
I'd love to be 240lbs at 6% bf....and be 6'4".
Semi-realistically, I'd like to be 210lbs at 7-8% bf. (doubt I can obtain that without chemical help. Not saying it's not possible, just not likely for me without someone else modifying my diet and training style)
220lbs at 7-8% would be cool too.
Most likely is me being inbetween 180lbs (cringe) and 200lbs with a lower bodyfat.
My old agent wanted me to drop down to 180lbs...I said no, lol.
It took a while for it to sink in with me, but skinnier ripped guys look "bigger" on film than big beefy guys (see Brad Pitt in Fight Club, Troy, and how many guys want to look "big" like him, lol, etc. It's all in the lighting and shadows.), as well as it allows me to be more marketable in other roles. So my quest for size has been replaced with quest for leaness (without stims). I'm also currently on this big flexibility kick for some reason, lol.
Summation:
look like a Men's Health model, except 20lbs heavier.
