Definitely more beer gut than bodybuilder, but not a fatty. Sorta an even distribution, with a bit more girth in the thighs and legs. I've got muscular calves, and when I built my FX initially, I had to shim them to give me extra clearance.
I had tried on a fellow member's RT-mod a couple years back, and that fit very well. I guess I was just wondering if any of the current sets is better suited to a shorter individual, but it sounds like each is generally scalable.
