Take it for what it's worth, but the results of my two "bulks"
172-202 waist from 33-37
175-190 waist from 33-35
I'm not including my newbie gains or going from my original 140lbs to 150, then to 160, then to 170, then to 180, then back down to 165, and back up to 175, etc.
Those were just my "ok, time to gain some fucking weight" attempts.
FWIW, I'm back down to 175 and have a 31 inch waist now. I've had injuries, setbacks, bullshit, etc in the time between all of these so its not like I went from 140 to 172 to 202 back down to 175 up to 190 back down to 175.
Edited: each time I bulked I didn't track progress with a tape measure or pics.. I was just focused on scale weight. I will never do that again.
